Rear Suspension

Rear Suspension

When installing waxed components, contact surfaces must be cleaned. Contact surfaces must be free of wax and grease.

Tightening specifications for unlubricated bolts and nuts are given.

Always replace self-locking nuts and bolts.

Always replace the bolts and nuts, which are tightened with an additional tightening angle.

Welding or straightening operations are not permitted on load-bearing or wheel-controlling components.

Always avoid the following actions with coil springs: Hammer stroke, welding beads, applying color identification later.

Do not perform any welding or grinding (separating work) in coil spring or suspension strut area! Cover coil spring or suspension struts if necessary.

When loosening, removing or installing hydraulic, pneumatic or electrical line, always make a sketch or take a picture. Doing so, record the original installation locations.

If the cable ties, brackets or mounting elements were removed during the repair procedure, they must be installed at their original location.

Do not let the drive axle hang down. The inner joint could be damaged if it is bent too far.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If the vehicle does have to be moved, always note the following points:

- Install an outer joint in place of the drive axle.

- Tighten the threaded connection between the drive axle and the wheel hub to 200 Nm.

Bonded rubber bushings can only be turned to a limited extent. Only tighten threaded connections at control arms if vehicle is in curb weight position or control position.

• Wheel bearing, lifting to curb weight position on vehicles with coil springs. Refer to => [ Wheel Bearing in Curb Weight, Lifting Vehicles with Coil Spring ] Description and Operation.

If the vehicle must still have an axle alignment, every bolt and nut that must be loosened for adjustment must be tightened to the tightening specification. Tighten the bolts and nuts to the specified additional tightening angle after the alignment/adjustment is complete.

All bolts and nuts must be tightened properly before driving the vehicle!

For a short period of time, subframes for AWD vehicles were installed on FWD vehicles, refer to the Parts Catalog

For a short period of time, wheel bearing housings for AWD vehicles were installed on FWD vehicles - item 24 - => [ (Item 24) Wheel Bearing Housing ] Wheel Bearing Housing, Wheel Bearing Unit and Coil Spring Shock Absorber Overview. Refer to the Parts Catalog. Do not install both types together.

For a short period, steel wheel bearing housings instead of aluminum wheel bearing housings were installed on FWD vehicles, refer to the Parts Catalog. Do not install both types together.
