Rear Suspension Overview, With Stabilizer Bar

CAUTION:

Threaded connections on the rear suspension, used to mount the bonded rubber bushings, must only be tightened with the vehicle resting on its wheels.

WARNING:

Before moving a car from which the driveshaft has been removed, first install an outer joint in place of the driveshaft-otherwise the wheel bearing will be damaged.

NOTE:

Do not attempt to weld or straighten rear wheel suspension components.
