side of the fifth wheel plate. Use a water
resistant lithium-base grease.
NOTE
The plate must be lifted up slightly to relieve
the weight of the bracket while applying
grease.
Front Axle and
Suspension
Lubrication and inspection of front axle
assemblies.
Axle Lubrication
Refer to the axle manufacturer's operator's
manual for lubrication specifications and
service intervals.
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.
