Caution! Use a wrench to prevent the nut on the upper support mounting bolt from turning by removing the plastic cap (see illustration 10.6).
7. Check the operation of the shock absorber, see the relevant chapter.
The shock absorber is installed in the reverse order of removal.
Tightening torques for threaded connections:
- upper support mounting bolt - 40 Nm + 45° turn
- lower support mounting bolt - 80 Nm + 90° turn
Caution: Secure the nut to the upper shock absorber support bolt with tape so that it does not fall off when you hold it from turning.

Before doing this, lubricate the centering seat of the wheel disc on the hub with a thin layer of grease.
Do not lubricate the wheel mounting bolts. Replace rusty bolts with new ones.
