Repair Information

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

Torque 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: Striking with a hammer, 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 records 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.

Lightly coat the splines on the outer joint with assembly paste before installing the outer joint into the wheel hub. Refer to the Parts Catalog.

Never allow the drive axle just to hang loose under the vehicle or to bend them at the joints.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If vehicle must be moved, observe the following:

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

- Tighten the outer joint to 120 Nm (twelve-point bolt) or 200 Nm (hex bolt).

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 => [ Wheel Bearing, Lifting To Curb Weight Position ] Front Suspension

• 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!

Note the following when working on a vehicle with the Start/Stop System:

Danger of personal injury caused by the engine starting automatically on vehicles with the Start/Stop System.

• When the Start/Stop System is on (recognizable by a message in the instrument cluster), the engine may start automatically.

• Make sure the Start/Stop System is off whenever working on the vehicle. Turn off the ignition and turn it back on only when necessary.
