The anti-roll bar is needed to reduce the roll of the car body when cornering - this improves handling and increases the average speed of the car. The anti-roll bar is essentially a torsion bar that connects the suspension elements of the right and left wheels. When turning, they twist, reducing roll. At the same time, the tendency for the car to rock is reduced.
During vehicle operation, the stabilizer bar and its mounting pads wear out slowly and do not require frequent replacement. The operation of replacing the cushions and removing the stabilizer bar is associated with a number of difficulties and is performed on a removed front subframe, therefore, if a malfunction occurs, it is advisable to contact a specialized service station. The main load is taken by the joints of the stabilizer struts, so they fail much more often. If the technical condition check of the front suspension reveals a malfunction of the stabilizer struts, they must be replaced.
Replacing the anti-roll bar struts
Warning: To avoid injury, replace the struts only when the stabilizer is in a relaxed state (both front wheels are suspended or evenly loaded with the weight of the vehicle).
1. Preparing the car for maintenance and repair
2. Place stops under the rear wheels and lift the front part of the car.
3. Remove the front wheels
4. Using a metal brush, clean the stabilizer bar pin nuts from dirt and rust...
...and treat them with penetrating lubricant.
5. Using an 18 mm open-end wrench, unscrew the nut of the upper mount of the stabilizer bar to the shock absorber bar bracket, holding the ball joint pin from turning with a TORX T40 wrench.
6. Remove the ball joint pin from the bracket.
7. Similarly, unscrew the nut, disconnect the lower hinge of the strut from the rod and remove the stabilizer strut.
Note: The rack mounting nuts are self-locking and cannot be reused, so they must be replaced with new ones during assembly.
8. Install the stabilizer bar in the reverse order. Tighten the fastening nuts to the prescribed torque of 65 Nm.
9. Similarly, replace the second anti-roll bar.
