Removing
Attention! Specific operations that apply only to models A 190 and A 210 are set out at the end of this chapter.
1. Remove the flange from the rear axle cross member (see illustration 7.9 in section «Brake system»).
2. Remove the rear shock absorber spring, see relevant chapter.
3. Remove the lower underbody protection, see relevant chapter.
4. Loosen the parking brake cable, see relevant chapter.
5. Disconnect the parking brake cable and wheel speed sensor wire from the trailing arm pinch bolt. Before disconnecting, mark the position of the cable clamps and cut them.
6. Disconnect the shock absorber from the trailing arm, see relevant chapter.
7. Unscrew a bolt of fastening of the stabilizer to the rear side of the trailing arm and remove the stabilizer.
Attention! Do not damage the limit shield.
8. Unscrew bolts of fastening of a basic board of the brake mechanism together with a protective cover to the longitudinal lever.
Attention! Do not change the bend of the brake pipe, and do not kink it. The brake line does not need to be removed.
9. Remove the fender liner near the attachment point of the trailing arm. To do this, remove the two clips from the bottom of the fender liner on the rear fender.
10. Remove the bolts that secure the trailing arm to the axle cross member.
Attention! High tightening torque. Risk of injury.
Installation
11. Fix the trailing arm to the rear axle beam by tightening the mounting bolts with a force of 140 Nm. After that, tighten them with a wrench another 90°.
12. Reinstall the fender liner, securing it with two clips.
Attention! If the protective cover has been detached from the brake support plate after removal, the sealing surfaces must be cleaned and the seal replaced before installation.
13. Fix the brake support plate together with the protective cover, if they were removed, on the trailing arm with a new bolt with a tightening torque of 35 Nm.
Attention! Do not change the bend of the brake pipe, and do not kink it.
14. Install the stabilizer with the limiter plate on the trailing arm and screw the stabilizer so that it stands without tension. Tighten the fastening bolt with a force of 70 Nm.
Attention! The stabilizer guards have different thicknesses.
15. Install the shock absorber on the trailing arm, see relevant chapter.
16. Attach the parking brake cable and wheel speed sensor wire to the trailing arm pinch bolt. Secure the parking brake cable with new clamps, installing them in the same places from which they were removed.
17. Install the lower underbody protection, see relevant chapter.
18. Install the damping spring, see relevant chapter.
19. Install the flange on the cross beam shank.
20. Adjust the parking brake, see relevant chapter.
Models A 190 and A 210
21. Remove the parking brake pads, see relevant chapter.
22. Disconnect the wheel speed sensor from the brake pad support shield. Sensor tightening torque 8 Nm.
23. Disconnect the bracket from the brake shoe support shield.
Tightening torques for additional threaded connections:
- support shield of the brake mechanism to the trailing arm - 35 Nm
- protective cover to the support plate of the brake mechanism - 10 Nm
