Operation CHARM: Car repair manuals for everyone.

Rear Suspension

^ If rear tire wear indicates that the axle housing may be bent, or rear springs mislocated, the alignment can be checked as follows:

a. Back the vehicle squarely onto an alignment machine.
b. Compensate for wheel runout the same as for checking front wheel toe-in.
c. Check camber reading which should be 0.03° negative to 0.05° positive.
d. Check the amount of toe-out which should be 0 to 0.05° or 0 to 1.58 mm (0 to 1/16 inch).

^ The rear wheels cannot be aligned by conventional means. The axle housing and springs, if bent or damaged, must be replaced. The frame under most circumstances could be straightened. The necessary straightening operations may be performed using frame straightening equipment or by relocating the spring to the axle without removing the axle housing from the vehicle. This procedure will allow checks during straightening operation to determine when the axle-spring assembly is within the correct limits.

^ If it is found that the frame and springs are within specification, the rear axle assembly itself is not straight and it must be replaced.

CAUTION: Under no circumstances should the axle housing be straightened to correct any alignment problems. If it is determined the axle assembly itself is not straight it must be replaced.
