Inspection; Wheel Alignment - Peterbilt 348 2017 Operator's Manual

Inspection

For all vehicles, mandatory
maintenance procedures include
retightening all U-bolts and inspecting
the suspension for loose fasteners,
abnormal wear, or damage. However,
even with proper maintenance, the
service life of leaf springs is affected
by many factors, such as: fatigue,
vehicle gross weight, type of load, road
conditions, and vehicle speed.
Check for cracks, wear marks, splits,
or other defects on the surface of
the spring. Defective parts must be
replaced. Because repaired springs
cannot be fully restored to their original
service life, replace the complete
assembly if cracks or other defects are
detected.
Visually inspect shock absorbers and
rubber bushings.

Wheel Alignment

For driving safety and comfort, and
to prolong the life of your vehicle, it
is important to have wheels correctly
aligned. Check tire wear frequently.
Uneven tire wear is a sign that the
wheels may be misaligned.
If you see uneven wear, take your
vehicle to an authorized dealer familiar
with aligning wheels on your vehicle.
