Kingpin Lubrication
Lubricate with approved lubricant.
Lubricate knuckle thrust bearings, knuckle
pins, and tie rod ends. Lack of lubrication
causes premature wear and hard steering.
Lubrication schedule may be shortened if
necessary.
Suspension Lubrication
Each standard spring anchor pin has a
grease fitting. Pressure lubricate spring
pins as specified. At regular intervals, the
spring leaves may be lubricated with a
rust-inhibiting oil applied with a spray gun
or brush. Depending on your suspension,
lubricate all spring pins until grease flows
out of both ends of the bushing. Look for
signs of rust or water in the flushed grease.
If a pin will not accept grease, it should be
removed, cleaned, and inspected.
CAUTION
DO NOT spray the suspension with
chemical products or mineral oil; it can
cause damage to the bushings.
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.
