Warning: If your vehicle has air suspension, relieve the pressure before beginning this procedure (see paragraph 4 of subsection 14).
Trailing arms
Warning: it is permissible to remove and install only one trailing arm at a time. This will prevent the rear axle housing from moving off the jack.
1. Loosen the wheel nuts. Raise the rear of the car and install vertical supports under the frame side members. To prevent the vehicle from rolling, place chocks under the front wheels. Remove the wheel.
2. Support the rear axle with a floor jack. It is necessary to disconnect the ride height sensor rod from the upper control arm that is removed on a vehicle with air suspension. Unscrew the nuts and remove the washers and bolts located at each end of the trailing arm (see illustrations).

15.2b. Upper trailing arm mounting bolts/nuts
3. Remove the lever. Inspect the bushings inside for cracks, hardened areas, or other signs of damage. If you need to replace them, check with the manufacturer's representative about the availability of such spare parts. If spare parts are available, purchase them and provide the lever to the auto repair shop for pressing out old bushings and pressing in new bushings.
4. Installation is carried out in the reverse order of removal. Before tightening the bolts/nuts, it is necessary to jack up the rear axle so that the normal ground clearance of the car is simulated, then tighten the fasteners to the required torques.
Lateral thrust
5. Raise the rear of the vehicle and install vertical supports under the frame side members. To prevent the vehicle from rolling, place chocks under the front wheels.
6. Remove the nuts/bolts located at each end of the rod (see illustration).
15.6. Tie rod bolts/nuts
7. Remove traction. Inspect the bushings inside for cracks, hardened areas, or other signs of damage. If you need to replace them, check with the manufacturer's representative about the availability of such spare parts. If spare parts are available, purchase them and provide the rod to the auto repair shop to press out old bushings and press in new bushings.
