General Information
CAUTION:
Risk of damaging the threads in the vehicle body.
- The bolts and nuts at all suspension parts must not be loosened or tightened with an impact wrench.
- Always install the bolts and nuts by hand for the first few turns.
- When installing waxed components, contact surfaces must be cleaned. Contact surfaces must be free of wax and grease.
- Tightening specifications for non-lubricated 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 strokes, 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 Information.
- 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 a vehicle must be moved, be sure to note the following:
- Install an outer joint in place of the drive axle.
- Tighten the outer joint to 200 Nm.
- Bonded rubber bushings have a limited range of motion. For this reason only tighten threaded connections at control arms if vehicle is in curb weight position. Refer to WHEEL BEARING IN CONTROL POSITION, LIFTING VEHICLES WITH AIR SUSPENSION .
- Always replace bonded rubber bushings on both sides of vehicle.
- If the vehicle must still have an axle alignment, only tighten the bolts and nuts that were loosened when making adjustments to the tightening specification. Tighten the bolts and nuts to the specified additional tightening angle after the alignment/adjustment is complete.
WARNING:
Risk of Accident.
- If vehicle will be driving on the streets, all screws and nuts must be tightened properly!
