Shock absorber leaking: consequences, is it possible to drive a car, what to do

Shock absorbers in a car dampen spring vibrations that occur when the vehicle overcomes bumps on the road. In the absence of shock absorbers, suspension springs would oscillate uncontrollably, which would lead to shaking of the car body, as well as loss of controllability and, as a result, an increased risk of accidents.

Most often, problems with the functioning of shock absorbers are associated with the appearance of drips. If drips are detected on one of the shock absorbers, operation of the machine is allowed, but you should plan to visit the workshop in the near future, since the problem still needs to be fixed.

Why did the new shock absorber leak?

There are times when you buy new shock absorbers for your car, come to a service station, they remove the old shock absorbers on your car and install new ones.
Together with them they install a new service kit (boots and shock absorber bumpers), and you drive away in your car with new shock absorbers installed. With the old shock absorbers, you felt that the car was somehow “sluggish” and “shaky.” I didn’t keep the road on a “washboard”, the extraneous knock on a not entirely smooth road (which in our city, and not only in our city, is about 99%) was just “sick”... You stopped at a service station. This service station was recommended to you by your good friends - they get their car repaired here. True, your car is a different brand than your friends. But, according to most car owners, the cars are the same. They (cars) all have four wheels, the wheels are round, and all cars are controlled by a steering wheel.

So, after installing new shock absorbers,

– we immediately felt the difference in driving. Everything became different. And immediately your car became somehow “knocked down”. Something in it has stopped annoyingly knocking, as they explained to you - this knocking was caused by wear of the shock absorber rod in the “working comfort zone”. This doesn't tell you much. You are happy with the result: although the shock absorbers are not cheap, the result is obvious.

But... After some 20-30 kilometers, it began to seem to you that the car began to “knock” again and stopped holding the road, returning to its condition, which was before replacing the shock absorbers and bumper guards. You begin to think that the reason is that you bought non-original shock absorbers. “Maybe I should have put on the original?” – you begin to think.

The next day, you come to the service station where your shock absorbers were changed. Tell us your thoughts about original and non-original shock absorbers. They listen to you carefully, say: “Perhaps,” and drive the car onto a lift for diagnostics.

When you lift the car, the defect immediately becomes obvious! Both shock absorbers leaked... There was some kind of smile on the faces of the mechanics. But this smile gives way to an incomprehensible grimace of bashful horror when they remove the shock absorber from the car and expose the shock absorber rod, removing the bumper boot from it... The shock absorber rod has traces of scuffing. Moreover, these scuffs on the rod are not longitudinal (in the direction of shock absorber operation), but transverse. It’s as if someone specially took and “pulled” the rod with some kind of tool, but it’s not clear why?!

Later it turns out that the careless mechanic who changed the shock absorbers had no idea how shock absorbers are changed correctly, as described in the technical literature. Later, of course, the owner of the service station will be forced to apologize to you and eliminate the defects in the work performed by his employee - at the expense of the service station. You no longer care about the fate of that careless mechanic; you want to leave the service station faster with a repaired car.

What can we advise to avoid getting into such situations? Defects at work and careless employees are found in many areas of human activity. “He who does nothing makes no mistakes,” the proverb tells us.

But, still: trust the repair of your car only to professionals. Buy spare parts only in a car store that you have verified and where you liked both the level at which you were served and the professionalism of the employees.

The shock absorber is leaking, what should I do?

Greetings, dear motorists! And again, we continue to study individual systems, components and parts of your car.

Quite a lot of motorists, in particular beginners, believe that the purpose of batteries is only to provide comfort while driving. This is true, but it is just one of the functions. How amazed novice motorists are when they don’t pay attention to leaking shock absorbers, and as a result they end up in a ditch. You wouldn't wish this on anyone!

What to do if the shock absorber starts to creak

One day during a trip, you heard that the rear or front shock absorbers began to creak. This means that it’s time to carry out not only diagnostics of the car’s suspension, but also diagnostics of the shock absorbers. If the shock absorber squeaks, this is a warning for you. When diagnosing the suspension, visually inspect the shock absorbers. If, upon inspection, you find that the shock absorber is leaking, then you should immediately repair or replace it.

Can you guess why? Yes, it’s simple, in the “best” case, only the suspension will suffer, in the worst case, you can become involved in an accident at any moment. How do you like this prospect? If you close your eyes to this, you will spend even more money, not only repairing the shock absorber, but also repairing the suspension. We advise you not to be lazy and visually inspect the shock absorbers systematically. Moreover, there is nothing complicated about it - you turn the wheels and make sure that the shock absorber is not leaking, that everything is normal. Most novice motorists, when diagnosing the condition of shock absorbers, make hasty conclusions about the malfunction of the shock absorbers when they see oil deposits on them. However, there is nothing wrong with this, this is a completely normal condition. But if you notice oil leaks, then replacement or repair certainly cannot be avoided.

What comes out of shock absorbers

To understand the question of why shock absorbers leak, you need to understand their design and operating principle. The shock absorbers themselves look like cylinders filled with liquid or gas. A piston with a rod is installed in them, and the element is sealed using rubber seals and gaskets.

During operation of the shock absorber, the piston and rod move through the mass inside the shock absorber. Since the travel is small due to the filling of the shock absorber and the tightness of the element, suspension vibrations can be damped, and only a small part of them is felt by drivers and passengers inside the car.

At the moment, oil, gas or mixed (in which there are separate chambers with oil and gas) shock absorbers are installed on cars. Only oil or mixed versions of the part can leak, and when gas escapes, the problem will be noticeable only by the “behavior” of the car.

Replacing or repairing a shock absorber - the choice is yours

The most common reason that the shock absorber began to leak is the loss of tightness. And all this because the operation of our vehicles takes place practically in combat conditions. However, this does not make it any easier. We need to act immediately. You make the decision whether to repair or replace shock absorbers yourself, relying on the following factors: – it is better to buy a new shock absorber if the cost of repairing and buying a new one is not very different; – provided that you have some skills, you can try to repair the shock absorber yourself using a repair kit.

Video - replacing the shock absorber

Pay attention to this point - most shock absorbers are currently non-separable parts. So, keep in mind that if a car repair shop offers you to restore a shock absorber, then this is a dubious idea, and it is unlikely to be profitable. You are not changing a light bulb, but a part that is responsible for your safety.

Based on practice, we can conclude that a restored shock absorber does not last that long, and then will require repair again. Therefore, if a problem has already emerged - the shock absorber is leaking, it is optimal to replace the shock absorbers. If the shock absorber is restored, it means it will last 5 thousand km, no more, but a new one, taking into account its quality and normal use of the car, will last 5 years, exactly.

Read the Repair and Operation Manual for your car; it should indicate what type of shock absorbers are installed on your car by the manufacturer. If shock absorbers with pumping are installed, then you only need to plug the hydraulic fluid pipes, and that’s all the repairs are. You can repair hydraulic or gas shock absorbers yourself. However, for this you will need special equipment, which you may not have in your garage. In this case, you have a direct route to specialists at a car service center, and this is again a minus in the budget. Practice shows that a leaking shock absorber is best replaced with a new one - this is the only correct solution.

I wish you success! Let such a problem as creaking shock absorbers be familiar to you only in theory!

Signs of faulty shock absorbers

There are two types of signs that a shock absorber has completely or partially failed. The first type is visual. In particular, they can be identified by visual inspection of the shock absorber. The second type of signs includes changes in the behavior of the car in motion. Let us first list the signs related to the second type, since first of all it is necessary to pay attention to how the behavior of the machine has changed, in particular:

Rocking when braking and accelerating . If the shock absorbers are working properly, then even with sharp braking the car should swing back no more than once, after which the shock absorber should dampen the oscillatory movements. If there are two or more swings, this is a symptom of partial or complete failure.
Roll when maneuvering . Here the situation is similar; after exiting a sharp roll when entering a turn, the body should not sway in the transverse plane. If so, the shock absorber has similarly failed.
Increased braking distance . This factor is due to the same swing during braking. That is, during prolonged braking, the shock absorber does not dampen vibration, and the car periodically lowers and raises the front part of the body. Because of this, the load on the front wheels is reduced, which reduces braking efficiency. The braking distance is especially longer for vehicles equipped with an anti-lock brake system. This is because the rear end rises and the ABS reduces the brake line pressure. Also, the braking distance increases when braking on uneven roads.
The car does not “hold” the road . In particular, when the steering wheel is installed in a straight position, the car constantly pulls to the side. Accordingly, the driver must constantly steer in order to align the trajectory of movement.
Discomfort when driving . It can manifest itself in different ways. In particular, some drivers and/or passengers feel discomfort from the rocking of the car when driving long distances; people suffering from “sea sickness” (the official name is kinetosis or motion sickness) can feel motion sick. This effect is a typical symptom of faulty rear shock absorbers.

What is the effect of a faulty shock absorber?

The use of worn shock absorbers can not only cause discomfort while driving, but also cause a real danger when driving the car. So, possible problems associated with a faulty shock absorber:

Reduced wheel grip. In particular, when the car rocks, the clutch will have a variable value.
Increased braking distance, especially on vehicles with an anti-lock braking system (ABS).
Some electronic systems of the car, such as ABS, ESP (exchange stability system) and others, may not operate correctly.
Deterioration in vehicle handling, especially when driving at high speed.
The appearance of “hydroplaning” when driving on a wet road at low speeds.
When driving at night, constant rocking of the front of the car can cause the headlights to blind oncoming drivers.
Discomfort when driving. This is especially true when driving long distances. For the driver, this threatens increased fatigue, and for people prone to seasickness, this is dangerous due to motion sickness.
Increased wear of tires, rubber bushings, silent blocks, bump stops and springs. and other elements of the car suspension.

Why do shock absorbers leak?

Gas or oil can escape from the cylinder if the seals are damaged. Rarely is the problem global in nature, and in most cases the oil leaks out of the shock absorbers slowly, leaving smudges that the driver can pay attention to, for example, when changing tires.

The reasons for damage to shock absorber seals are commonplace: the service life has reached the end, poor performance of the part or physical damage due to driving on bad roads.

Causes of shock absorber malfunction

The causes of failure are usually natural factors, including:

Aging of shock-absorbing fluid (oil). Like other technological fluids in a car, the oil in the shock absorber gradually gains moisture and loses its performance properties. Naturally, this leads to the fact that the shock absorber begins to work harder than it worked before. However, it must be understood that fluid aging does not happen overnight, with the exception of a rupture of the seal on the shock absorber body.
Torn seal. In particular, the sealing of the piston and the inner walls of the working cylinder. The oil seal can rupture due to external factors or simply due to the aging process. It, like any rubber seal, becomes tanned over time and begins to leak liquid. Because of this, oil leaks from the shock absorber, as well as moisture from the outside entering the oil, which leads to a deterioration in its performance.
Deformation of the valve mechanism plates. This process is also natural and occurs on an ongoing basis, albeit at different speeds. Thus, the rate of deformation depends on two main factors - the quality of the shock absorber (the quality of the metal of the plates) and the operating conditions of the machine (naturally, a significant impact load leads to premature deformation).
Gas leak. This is true for gas-filled shock absorbers. The idea here is the same as for oil-filled devices. Gas here performs a damping function, and if it is not there, then the shock absorber will not work.
Failure of silent blocks. They wear out due to natural reasons, losing their elasticity and performance. These components are practically not subject to repair, so if they fail, they simply need to be replaced (if possible, or the shock absorbers must be completely changed).

Consequences if not changed

Well, my dear, you are frugal - if you don’t change 1 leaking rack on time, then the rest will follow it in a circle. Why? Yes, everything is simple - the car is designed to hold 4 sides, that is, all 4 shock absorbers must work. If one fails, the entire load is transferred to 3 sides, but they are not designed for it - and they begin to break. And with each failure, the load is redistributed into two, etc.

In simple words - if you don’t replace 1 strut in time (as you noticed right away, you can drive for up to a week while you wait for the part), then in a month the second one will come out, then the third one and then the last one. That is, there is a big chance that if you don’t replace one, you can replace them all at once!

If this doesn’t scare you, well, I’ll ride in a rocking car, so what, let’s read other consequences:

The suspension will break through faster, and accordingly, all the parts involved in it will begin to fail, but first of all, all kinds of rubber bands will begin to “die” - silent blocks, bushings, even ball and steering ends. Those vibrations that the shock absorber should absorb will begin to be absorbed by the entire suspension.
There is a high probability that you will tear off something from the bottom of the car, for example, on the bottom, a muffler, for example. How? Yes, it’s simple - you won’t be tossed around like a child, but what if there’s a rut? Goodbye "glushak".
Controllability will drop significantly. Such a car is practically uncontrollable at high speeds. As I already wrote, skidding, swaying, can simply throw you into oncoming traffic when maneuvering.

I repeat again guys, you need to change it as soon as you notice “snot” (smudges). After all, if the rack is “snotty” and has just started to leak, it still holds for some time until all the oil comes out of the housing, but then it becomes empty and simply does not work.

So you have a week - well, two at most. Order and change, you will save others from damage.

That's all, I think it was useful.

How to determine if shock absorbers are faulty

Car owners are not without reason concerned about the question of how to check an oil or gas-oil shock absorber. This is due to the fact that modern shock-absorbing devices often have a more complex design than older models, which makes diagnostic measures more complicated. Therefore, ideally, they should be checked in a car service center on a special stand. However, there are a number of “garage” verification methods.

Body rocking

The simplest, “old-fashioned” method is to rock the car body. In particular, they rock its front or rear part, or the shock absorbers separately. You need to swing it strongly, but do not bend the body elements (in practice, such cases occur!). In theory, you need to achieve the maximum possible swing amplitude, then release the body and look at its further vibrations.

If the shock absorber is working properly, the body will make one swing (or one and a half), after which it will calm down and remain in its original position. If the shock absorber has a malfunction, the body will make two or more oscillations. In this case, it must be replaced.

It is worth noting, however, that the rocking method is suitable for cars with a simple suspension system, for example, the VAZ “classic” (models from VAZ-2101 to VAZ-2107). Modern cars often use complex (often multi-link) suspension, so it will dampen the resulting vibrations even with faulty shock absorbers. Therefore, with the help of body rocking, by and large, it is possible to determine two borderline states - the damper is completely out of order, or it jams during operation. It is not easy to identify the “average” states of the shock absorber using swinging.

Visual inspection

When diagnosing a problem shock absorber, be sure to perform a visual inspection. To do this, you need to drive the car into a viewing hole or lift it on a lift. You can, of course, dismantle the shock absorber, but this can take a lot of time and effort. During the inspection, be sure to check for oil smudges on the shock absorber body. You can wipe off traces of oil with a rag and leave it like that for several days. After this period, the test should be repeated.

If the car is raised on a lift, it is advisable to check the condition of the shock absorber rods. They should not show any signs of rust or damage. If they are present, then the device is at least partially faulty and additional diagnostics need to be performed.

When inspecting, be sure to pay attention to the wear pattern of the tires. Often, when shock absorbers are broken, they wear unevenly; as a rule, the main wear occurs on the inside of the tire. There may also be isolated bald spots of wear on the rubber. However, tread wear may also indicate other failures in the suspension elements, so additional diagnostics are also needed here.

If faults in the front shock absorber (strut) are checked, a mandatory inspection of the springs and upper supports must be performed. Shock-absorbing springs must be intact and free of cracks and mechanical damage.

Machine control check

If the shock absorber/shock absorbers are faulty, then while driving the driver will feel that the car is “scouring” along the road, that is, it will be necessary to constantly steer in order to keep it in the rut. When accelerating and braking, the car will sway. The situation is similar with lateral body tilts. In this case, it is not necessary to accelerate to a significant speed; the city speed limit is quite suitable for testing. In particular, at a speed of 50...60 km/h you can do sharp acceleration, braking, and snake.

Change or... repair: how and why shock absorbers are repaired

Of course, a sharp-tongued reader will say: someone who buys a car for several million can easily spend a hundred or two on racks. This is, of course, true, but only at first glance. Firstly, consider the quality of the road surface, which is far from desired, and imagine how quickly new shock absorbers installed on a car weighing more than 2.5 tons will die. Secondly, one should not discount the fact that people driving a GL500 have the ability to calculate expenses. And at the end of the virtual tour, imagine that you, the owner of the X5, are told: “Repairing one shock absorber will cost you 350 euros.” Almost 5 times cheaper! And what will be your decision after this?

We won’t talk about the design of shock absorbers: enough was said in the article about replacing struts . Today we will focus exclusively on breakdowns and their elimination.

Breakdowns

One of the most common shock absorber malfunctions is leakage of working fluid through a damaged oil seal. There are several reasons why it comes to an end, and the main one is friction. The simplest option is when the service life has expired and the sealing part has worn out. But it happens that the shock absorber begins to “sweat” or leak before reaching half of its service life.

Articles / History Softness and hardness of the suspension - what is more important for comfort? Almost every car owner is sure that a soft suspension provides comfort, while a hard one makes the car sportier and allows better grip on the road. But as in many other cases,... 87454 1 37 03/05/2015

The reason for this may be winter - or rather, frost . For example, you drove out of a warm garage somewhere, stopped to drink hot chocolate and sat for a while in a coffee shop. Due to heating and subsequent sharp cooling in the cold, grains of ice formed on the shock absorber rod. They will tear the seal on a relatively new shock absorber. In addition, death of the seal can also occur after dust and dirt get on the rod due to damage to the boot.

The rod itself is difficult to “kill,” but it moves in the guide sleeve, into which Teflon rings are, in turn, pressed. These rings, of course, wear out, and then the rod begins to experience shock loads in the contact surface. If you do not pay attention to this in time, you can break the entire guide sleeve - and this is already a disaster from the point of view of driving safety. Well, there’s nothing to say about the shock absorber bushings; they can break first. Replacing them is not a big problem, but it happens that this is simply not provided for structurally.

Diagnostics

Every car enthusiast knows: if you rock the car and it oscillates, as if on waves, it is clear that not everything is in order with the shock absorbers. Leaks of working fluid also quickly reveal at least wear of the oil seal. But if suddenly the rocking of the car does not provide any understanding of the problem, and the behavior of the car in motion is noticeably different from normal, a special diagnostic stand can come to the rescue. There are many of them on the market - for example, we used Emmetec.

The shock absorber is fixed in the stand: the body - in the moving part, the rod - to the plate with a strain gauge. The stand simulates the operation of a shock absorber, moving it either slowly or quickly. Thanks to the sensor, a graph of shock absorber stiffness is drawn during rebound and compression strokes in different operating modes. The master knows what the graph should look like, and if, instead of smooth curves, he suddenly sees any jumps or sharp transitions, he will give an approximate, but more specific conclusion about the technical condition of the “shock.”

Repair

In any case, if the shock absorber ends up in a repair shop, it is disassembled - although this is not so simple. The fact is that in the old days, shock absorbers were initially collapsible. Repair kits for them could be purchased at any store... or almost any. Nowadays, it is not profitable for manufacturers to have a part that can be repaired, so they are either welded or rolled from the factory.

Rolling also varies, and the difficulty of disassembly depends on this. If the shock absorber is single-tube gas-filled, then the gas is first bleed from it. After cutting off the retaining part and pulling out the insides, all parts are thoroughly washed in kerosene.

In any case, after disassembly, whatever the initial reason, the piston o-ring, the oil seal and the Teflon ring of the guide sleeve, as well as the shock absorber fluid are replaced.

If corrosion is found on the rod, it will undoubtedly be replaced. It will not be possible to sharpen and polish it - this is not a cylinder block with repair dimensions , this is not included structurally, and in addition there is a need for chrome plating.

The latter is a rather expensive pleasure, and therefore impractical. But in case of very minor “grinding”, the rod can still be polished with GOI paste.

Particles getting under the valves can be “treated” by regular washing and checking the surface so that the valve fit is normal.

The problem of the bottom valve in two-pipe systems was discussed above: so, in the event of a malfunction, this valve is replaced as an assembly.

For monotube shock absorbers, the sealing ring of the separating piston is replaced. The inner surface of the piston cylinder is also polished. Sometimes it happens that turning a rod yourself is easier and cheaper than ordering a new one - this applies to various types of tuning shock absorbers. And in our case, not only the rod was machined, but also the external gas-filled cylinder of the shock absorber, since the original one had lost its seal.

By the way, one of the problems on the way to repairing shock absorbers may be their “Americanness” - the inch calculation system, which can get in the way of selecting seals. In general, there is no shortage of components and repair kits, which is why repairs are overall cheaper than new ones.

The liquid used to fill shock absorbers is different and from different manufacturers, but the search for the ideal one never ends.

Our master said that a long search for the ideal working fluid in terms of price/quality ratio led to AMG-10 aviation oil. It turns out cheap and of very high quality, and at the same time you don’t overpay for a sensational brand.

The desire to speed up the course of history... 15149 0 3 09/05/2016

Well, another – perhaps the most pleasant – feature of the repair is that the master has the opportunity, albeit within a small range, to reconfigure the characteristics of the shock absorber. This will be clearer with an example, fortunately there was one: a Kia Sportage was brought from a Middle Eastern country. In general, the car is like a car - but driving on the domestic road surface was comparable to jumping on a jackhammer. The owner got tired of it, and he turned to the workshop. For the master, this was the first experience of “opening” a completely new shock absorber, which had traveled 300 kilometers. The owner was very pleased with the result of the reconfiguration - due to the fact that he received a normal suspension for relatively little money.

In addition, if you wish, the shock absorber can be made adjustable by installing a cover with a spool. By increasing or decreasing gas pressure, you can slightly interfere with the characteristics of compression and rebound stiffness.

After renovation

After completing all repair operations, the shock absorber is assembled together. Having already disassembled a non-separable part, there is no point in making it non-separable again. What do you do with “opened” shock absorbers? They cut off part of the body and weld on a new one, the same size, but with a thicker wall so that threading can be made.

To ensure the reliability of the seam, use a special cutting and welding stand. Assembly is completed by installing and tightening the fastening nut.

Now the shock absorber with working fluid must be filled with gas to create a gas boost. If the shock absorber is double-tube, then a special adapter is used for this, installed above the rod and slightly expanding the lip of the oil seal.

If the design is single-pipe, then a cover with a spool is made, which is installed in the housing.

It is worth mentioning that there were designs that made it possible to fill a single-pipe without interfering with the structure or compromising its integrity. We are talking, for example, about the shock absorbers of the old Audi A8. Single-pipe, collapsible - happiness for a repairman... But they too have sunk into oblivion.

Having assembled the shock absorber completely and filled it with gas, it is again sent to the stand to calm the conscience of the master who repaired it. If everything is in order with the schedule, the shock absorber goes to the warehouse and then to the owner. If desired, the body can be painted in the “original” black color.

Resource

The most exciting question that bothered us at the beginning of the conversation concerned the service life of the shock absorber after its repair. From smart books, for example, we know that after a “overhaul” the life of an internal combustion engine is restored to no more than 70–80% of the new one. In the case of shock absorbers, the master assured that the service life is restored by almost 100%. Some manufacturers provide a one-year guarantee on new shock absorbers without mileage limitation - well, not all, but a certain part of the workshops can confidently give the same guarantee after repair. But it’s up to you to decide whether to repair them or change them.

Afterword

It’s an interesting thing: they say that if a car has been driven on good roads, like European ones, it means that its shock absorbers are initially in good order and can last for more than one thousand kilometers – not like over our potholes. But in practice, it turns out that they are replaced at approximately the same frequency, regardless of geography - just the nature of wear is different. Due to large strokes and extreme points, bushings and oil seals break. They have small strokes, but this only means that the rod will be subject to increased load in a very small range, which will “wipe” it. So a good road is not always the key to “immortal” shock absorbers.

When to change a shock absorber

It is necessary to understand that regardless of the quality of the shock absorber, as well as the operating conditions of the machine, wear of this unit occurs constantly. With more or less speed, but constantly! Accordingly, their condition also needs to be checked constantly. Most shock absorber manufacturers in the mid-price category recommend checking every 20...30 thousand kilometers . As for replacement, usually the shock absorber wears out significantly after approximately 80...100 thousand kilometers . At this stage, you need to check it more thoroughly and, if necessary, replace it.

To ensure that shock absorbers last as long as possible, follow these recommendations:

Do not overload the machine . The manual for any vehicle directly states its maximum load capacity. You should not overload the car, because this is harmful to its various components - including the engine and suspension components, in particular shock absorbers.
Let it get into working mode . When driving a car in the cold season (especially during significant frosts), try to drive the first 500...1000 meters at low speed and avoiding bumps. This will allow the oil to warm up and spread.

Thus, if problems arise with the shock absorbers, it is better not to tighten it and replace the problem units with new ones. As for the purchase, it is better to buy licensed shock absorbers from the “officials”. Or choose products in trusted stores based on reviews from car enthusiasts.

Is it possible to drive and possible consequences

Now let’s answer the most common question: is it possible to drive if the shock absorber is leaking? As was said at the very beginning of the article - you can’t. This is a practice-tested rule, to which there is only one exception. We’ll get back to it a little later, but for now let’s look at the possible consequences of driving on racks that have leaked.

Firstly , if the shock absorber is leaking even just a little, this means that it is already less able to handle the load than initially. Accordingly, its resource will rapidly decrease, and there is a high probability of missing the moment when the machine will be left without this important element.

Secondly , if the rear shock absorbers are leaking, the braking distance may increase significantly. There is information on the Internet that at a speed of 80 km/h it becomes 15% longer in this situation. In addition, if the car is equipped with an ABS system, due to inoperative rear struts, it does not work properly.

Thirdly , when shock loads are ineffectively absorbed by the suspension, all its parts are subject to accelerated wear. Including ball joints, steering tips, and rubber dampers. Even rubber wears out faster.

Hence such a categorical answer to the question. Yes. Certainly. When a shock absorber leaks, you can drive more carefully, slowly, and so on. But anyway, the process has already begun. Unfortunately, the pendant cannot heal itself. Therefore, if at least one shock absorber is leaking, you should not drive the car.

The shock absorbers (struts) are leaking. What to do and is it possible to drive? What will be the consequences
