FRONT AXLE AND
SUSPENSION

Axle Lubrication

Change bearing lubrication when seals
are replaced, or brakes are relined.
See Preventive Maintenance Schedule
on page 5-12.
Thoroughly clean hubs and bearings
with solvent and a stiff bristle brush,
then dry and inspect components for
wear or damage. Re-lubricate with
approved axle lubricant.
(04/13)
Kingpin Lubrication
Lubricate with approved lubricant.
Lubricate knuckle thrust bearings,
knuckle pins, and tie rod ends. See
Preventive Maintenance Schedule
on page 5-12. Lack of lubrication
causes premature wear and hard
steering. Lubrication schedule may be
shortened if necessary.

FRONT AXLE AND SUSPENSION

Suspension Lubrication
Each standard spring anchor pin
has a grease fitting. Pressure
lubricate spring pins as specified. See
Preventive Maintenance Schedule on
page 5-12.
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.
