General Repair Information

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

Torque specifications for un-lubricated bolts and nuts are given.

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.

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

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

- Tighten outer joint 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, with Coil Spring, Lifting to Curb Weight Position ] Wheel Bearing, with Coil Spring, Lifting to Curb Weight Position.

• Wheel bearing, lifting to control position on vehicles with air suspension, refer to => [ Wheel Bearing, with Air Suspension, Lifting to Curb Weight Position ] Wheel Bearing, with Air Suspension, Lifting to Curb Weight Position.

• If the vehicle must still have an axle alignment, every screw 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.


If vehicle will be driving on the streets, all screws and nuts must be tightened properly!
