Rear Axle Components, Layout

General notes:

Load-bearing components or parts of the suspension must not be welded or straightened.

Do not attempt to move a vehicle on which the drive axle has been removed as this will result in wheel bearing damage. If the vehicle does have to be moved, always note the points:

^ Install an outer joint in place of the drive axle .
^ Tighten the outer joint to 50 Nm (37 ft. lbs.).

Bonded rubber bushings can only be turned to a limited extent. The bolted connections on the suspension links should therefore only be tightened when the vehicle is standing on the ground.

The procedure for retrofitting sports suspension is described in the installing instructions for sports suspension.

Vehicles with headlight vertical aim control, Refer to Lighting and Horns.
