1.1 General Information
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.
Vehicles without a drive axle must not be moved, otherwise the
wheel bearing will be damaged. If vehicle must be moved, ob‐
serve the following:
– Install an outer joint in place of the drive axle.
– Tighten outer joint to 150 Nm.
Never allow the drive axle just to hang loose under the vehicle or
to bend them at the joints.
Always replace self-locking nuts and bolts.
Always replace the bolts and nuts, which are tightened with an
additional tightening angle.
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
⇒ “1.4 Wheel Bearing in Curb Weight, Lifting Vehicles with Coil
Spring”, page 118 .
♦ Wheel bearing, lifting to control position on vehicles with air
suspension, refer to
⇒ “1.5 Wheel Bearing in Control Position, Lifting Vehicles with
Air Suspension”, page 120 .
Note
If the vehicle must still be aligned, every screw and nut that must
be loosened for adjustment is only tightened to torque specifica‐
tion. Tighten the bolts and nuts to the specified additional tight‐
ening angle after the alignment/adjustment is complete.
