Hang the car and remove the wheel. Disconnect the ground clearance sensor rod from the rocker arm. Loosen the pipelines to the distribution manifold, this will reduce the pressure in it.
Disconnect the shock absorber and stabilizer bar mounting strut from the rocker arm. Mark the position of the eccentric bolt in relation to the rear axle beam (arrows, Fig. 14.40), which will make it easier to adjust the wheel alignment later when installing the old rocker arm.
Unscrew the nut (20, see Fig. 14.3) and remove the eccentric bolt (18). Unscrew the bolt (16) with a flange and support the support (1) of the wheel bearing with a garage jack. Unscrew the nut (22) securing the swing arm (15), remove the bolt (21) and remove the swing arm.
The rocker arm should be installed in the reverse order, replacing the rocker arm self-locking nut (22) and tightening it by hand. Insert the lock nut (17) into the socket on the rear axle beam and tighten the bolt (16) by hand. Replace the self-locking nut (20), installing it with the eccentric disk (19) and tightening it by hand. Tighten the new anti-roll bar strut mounting nut to a torque of 100 N·m (10.0 kgf·m).
Next, with the vehicle loaded and standing on its wheels, tighten to the following torque:
- nut (22) 250 Nm (25.0 kgf·m);
- bolt (16) 100 Nm (10.0 kgf·m);
- bolt (18) 165 Nm (16.5 kgf·m).
Adjust the wheel alignment angles. On a car with a spring spring, the rocker arm should be replaced in a similar order, but it is necessary to remove the integral arm.
