Removal
1. Mark the position of the front wheels in relation to the hub with paint. This will allow the removed wheel to be put back in the same position it was in before. Loosen the wheel bolts with the car on the ground, then place it on stands, unscrew the bolts completely and remove the front wheels.
2. Unscrew the steering shock absorber (46) from the steering rod (11). Unscrew the fastening nuts of the pendulum arm joints (26) from the steering knuckle (23) and on the steering knuckles. In doing so, hold the joint journals with a size 5 Allen key.

3. Remove the steering linkage joints using puller 050 or HAZET 779.
Caution! Do not damage the rubber cuffs.
Examination
1. Move the joints by the trunnions. If the movement is too easy or there is play, replace the steering linkage arm tip.
Attention! The left trapezoid joint is intended for turning only (does not bend).
2. Check the anthers for damage and leaks (the lubricant contained within them protrudes out). If the dust boots are damaged, replace the rod end and, accordingly, the rod, since dirt that gets inside will disable the joint in a short time.
Attention! If the cuff is damaged only during removal, it is sufficient to replace the cuff.
Installation
1. Clean the grease from the pivot pins of the trapezoid joints, as well as the seats in the control levers.
2. Insert the pivot pins tightly into the cones of the corresponding levers.
3. Fit new self-locking nuts, holding the trunnion with an Allen key, and tighten the nuts to 50 Nm.
4. Screw the steering shock absorber using a new self-locking nut, tightening it to a torque of 35 Nm to the steering rod.
5. Position the front wheels so that the markings match when removed. Screw the wheels on. Remove the vehicle from the stands and tighten the wheel mounting bolts to 110 N·m in a cross pattern.
6. Check the alignment.
Caution: For safety, before starting your ride, double check that all tie rod pivots have new self-locking nuts and are tightened to the correct torque.
