Removal
Attention! Specific operations, which only apply to models A 190 and A 210, are described 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 suspension shock spring, see the relevant chapter.
3. Remove the lower underbody protection, see the relevant chapter.
4. Loosen the parking brake cable tension, see the relevant chapter.
5. Disconnect the parking brake cable and wheel speed sensor wire from the trailing arm clamp bolt. Before disconnecting, mark the position of the cable clamps and cut them.
6. Disconnect the shock absorber from the trailing arm, see the relevant chapter.
7. Unscrew the bolt securing the stabilizer to the rear side of the trailing arm and remove the stabilizer.
Caution! Do not damage the limit shield.
8. Unscrew the bolts securing the brake mechanism support shield together with the protective cover to the trailing arm.
Caution! Do not change the bend of the brake pipe, and do not bend it. There is no need to remove the brake pipe.
9. Remove the mudguard liner near the trailing arm mounting point. To do this, remove the two clips from the bottom of the mudguard liner on the rear wing.
10. Unscrew the bolts that secure the trailing arm to the axle cross member.
Warning! High tightening torque. Risk of injury.
Installation
11. Secure the trailing arm to the rear axle beam by tightening the mounting bolts to 140 Nm. Then tighten them another 90° with a wrench.
12. Install the mudguard liner in place, securing it with two fasteners.
Caution! If the protective cover has been disconnected from the brake mechanism support shield after removal, the sealing surfaces should be cleaned and the seal should be replaced before installation.
13. Secure the brake support shield together with the protective cover, if they were removed, to the trailing arm with a new bolt and tightening torque of 35 Nm.
Caution: Do not change the bend of the brake pipe or bend it too much.
14. Install the stabilizer with the limiting shield on the longitudinal arm and screw the stabilizer so that it stands without tension. Tighten the mounting bolt with a force of 70 Nm.
Please note! The stabilizer limiting shields have different thicknesses.
15. Install the shock absorber on the trailing arm, see the relevant chapter.
16. Secure the parking brake cable and the wheel speed sensor wire to the trailing arm clamp 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 the relevant chapter.
18. Install the shock absorber spring, see the relevant chapter.
19. Install the flange onto the cross beam tail.
20. Adjust the parking brake, see the relevant chapter.
Models A 190 and A 210
21. Remove the parking brake shoes, see the relevant chapter.
22. Disconnect the wheel speed sensor from the brake shoe support shield. The sensor tightening torque is 8 Nm.
23. Disconnect the bracket from the brake shoe support shield.
Tightening torques for additional threaded connections:
- brake mechanism support shield to the trailing arm - 35 Nm
- protective cover to the brake mechanism support shield - 10 Nm
