Changing front stabilizer bushings on Lada Vesta

The main stages of replacing stabilizer bushings:

1. We place the car within the perimeter of the repair area and raise it with a hydraulic lift.
2. Remove the front wheels.
3. Unscrew the upper and lower fastenings of the stabilizer strut (bone).
4. Unscrew the bolts and remove the left seal.
5. We unscrew the five bolts (at “10”), slide the protective cover of the steering rack, and remove the right one.
6. We install new rubber (polyurethane) bushings.
7. We assemble the structure in reverse order.

Resource for replacing rubber seals of the front stabilizer

It is difficult to answer unequivocally how much seals cost in each specific case.

The manufacturer indicates an average replacement interval of 60 - 80 thousand km.

The interval varies depending on a number of factors:

• quality of the road surface;
• speed limits;
• driving style;
• quality of spare parts;
• temperature conditions.

How to dismantle the stabilizer

We carry out the dismantling operation in strict adherence to the following algorithm of actions:

1. We lift the Lada Vesta car so that the front wheels are hanging at the same level. This is required to prevent the occurrence of obliquely directed stresses in the stabilizer.
2. We dismantle the lower protective casing to ensure easy access to the unit scheduled for repair.
3. We unscrew the bolts that hold the stabilizer links to the suspension components. Now we release the racks from their seats.
4. Correct installation of new bushings will require complete disassembly of the unit. We unscrew the bolts that secure the fixing brackets.
5. We dismantle the stabilizer.

Removing old and installing new products

1. We carefully pull the worn elements off the rod (you can cut them off).
2. We clean the stabilizer itself from dirt and carefully inspect it to ensure there are no deformations. If any are present, it is recommended to replace the product.

Installing a stabilizer on Vesta

1. Lubricate the surface of the stabilizer with the indicated product.
2. We put on the elements. We achieve a tight fit. The presence of backlash is excluded.

If such requirements are achieved, then we assemble the unit using the reverse algorithm.

1. We mount the stabilizer in its place. To do this, we install brackets that hold the bushings. We “bait” the fasteners.
2. We attach the rack to the edges of the stabilizer. Here you can tighten the fasteners to the required torque.
3. After this, you can tighten the fasteners of the brackets. The torque should be in the range from 18 to 24 N*m. This restriction is intended to “protect” the owner from the risk of stripping the threads in the fastener holes.
4. We return the protective casing to its original place.

Replacing stabilizer bushings on Lada Vesta

Necessary tools, materials:

• Torx wrench with set of sockets;
• ring, ring wrenches;
• knob, heads;
• Silicone based lubricant.

Sequencing:

1. We hang the car with a lifting mechanism.
2. We turn on the first gear to lock the front wheel drive.
3. Unscrew the bolts and remove the wheels and tires one by one.
4. We unscrew the nuts of the upper and lower fastening of the stabilizer (bones), use the head at “17”.
5. Using a key set to “17”, release the two bolts securing the metal bracket on the torsion bar on the left side. Access to the rubber bushing is unobstructed.

6. To replace the bushing, first remove the steering rack protection on the right side. Fixation of the structure with five bolts, size “10”.
7. Unscrew the right bushing.
8. We unscrew the two rear bolts securing the metal bracket.
9. We clean the surface of the torsion bar from dirt and deposits, and lubricate it with silicone grease.
10. We put on new rubber seals.

11. We assemble the structure in the reverse order with a tightening torque of 1.8-2.4 kgf.m.

Self-replacement of bushings on Lada Vesta is completed.

Note to the driver! It is not necessary to make a longitudinal cut when installing seals. The presence of an incision contributes to:

• penetration of sand, dirt, moisture into the gum;
• backlash formation;
• deformation of the seal.

Recommendations for selection

Service center technicians recommend purchasing spare parts and components from certified points of sale and official representative offices in order to reduce the likelihood of purchasing counterfeits.

Carefully check the catalog numbers with the dimensions specified in the operating instructions. If you have any doubts about the quality or origin, refuse to purchase.

Conclusion

Replacing the front stabilizer bushings and rods requires careful attention on the part of the repairman. Violation of the technological process will lead to deformation of the structure.

What type of sealing sleeve to purchase is up to the owner to decide on his own, but motorists recommend polyurethane ones. Their service life is 4 times longer than rubber ones. Polyurethane bushings retain their shape better and remain elastic regardless of the ambient temperature, which ensures a high level of controllability of the technical device.

Which bushings should I choose for replacement?

As we found out, the original products are not of decent quality, so you will need to look for analogues. And the main thing is to decide which bushings are suitable.

Here we look at some options for resolving the issue:

• many small manufacturers already produce stabilizer bushings, the material of which is polyurethane (it is less prone to mechanical and chemical stress compared to rubber);
• purchase stabilizer bushings for Kia; the parts fit perfectly in size and have a sufficient level of quality, and it doesn’t matter whether these are original stabilizer bushings or analogues.

Important! When purchasing bushings, pay attention to the identical geometric parameters, otherwise it will be impossible to install them.

Checking bushings for wear

The main cause of wear on these parts is dust and dirt getting between the bushing and the rod. The main indicator of bushing wear is a characteristic squeak that occurs when a car drives over road irregularities.

The sound can be heard well even inside the car, when driving at low speeds. Extraneous sounds that occur during such driving in the front of the car should be a reason for diagnosing the stabilizer. To do this you need to do the following:

• drive into a viewing hole or lift the car on a lift;
• remove both front wheels;
• visually check each bushing for wear, cracks and rubber squeezing out from under the mounting clamp;
• install the mounting blade and press it several times on the rod from above or below so as to simulate the operation of the stabilizer when moving.

If the bushings have wear, it will manifest itself as an unpleasant squeak when the barbell swings.

Briefly about the purpose and operating principle of the SPU

The VAZ team partially borrowed the design solution for the front suspension from their colleagues from Renault. In order for the replacement of stabilizer bushings on a Lada Vesta to be carried out purposefully and effectively, the cause of the breakdown must be correctly determined. For this, knowledge about the role of the SPU unit, as well as signs indicating the need for its repair, will not hurt.

A maneuver performed at speed definitely causes a side roll of the body, which can cause the car to roll over. It is to eliminate such consequences that a torsion-type anti-roll bar (STS) has been introduced into the front suspension. On Vesta, the part is installed only on the front axle of the car; its design features include the following facts:

• The main element is made of spring steel grades in the form of a round rod of a certain configuration.
• The rod is attached to the subframe using steel clamps and rubber bushings.
• Along the edges, the rod is attached to the front suspension struts using levers.

Principle of operation

Knowledge of the operating principles of this unit will help you understand the need to replace stabilizer bushings on a Lada Vesta car. They are based on the uniform redistribution of loads between the suspension elements. During lateral rolls, the stabilizer rods move in different directions. As a result, one end of the rod rises and the other goes down.

Rubber cushions that fix the middle part of the SPU allow it to twist around its axis with increasing body roll, due to which the position of the car on the track is adjusted. When making turns, the stabilizer struts additionally provide a high level of tire adhesion to the road surface.
