Rear Axle Alignment - Peterbilt 579 Operator's Manual

Rear Axle Alignment

Continual road shock and load
stresses may force the rear axles
out of alignment. If you detect rapid
tire wear on the rear axles, you may
have misaligned axles. If you suspect
rapid tire wear, have your rear axle
alignment checked and adjusted by an
authorized dealer.
In addition to pre-delivery inspections,
suspension alignment should be
checked when any one of the following
conditions exist:
•
Discovery of loose suspension
fasteners. (Loose, defined as any
torque below the recommended
torque value.)
•
Discovery of elongated holes in a
suspension component.
•
Bushing replacement.
•
Excessive or abnormal tire wear.
