PREVENTIVE MAINTENANCE
FRONT AXLE AND SUSPENSION
AXLE LUBRICATION
• Change bearing lubrication when seats are replaced, or brakes
are relined. See Recommended Maintenance Schedules, pages
315-342.
• 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.
KINGPIN LUBRICATION
• Lubricate with approved lubricant. Lubricate knuckle thrust bearings,
knuckle pins and tie rod ends. See Recommended Maintenance
Schedules, page 315-342. Lack of lubrication causes premature
wear and hard steering. Lubrication schedule may be shortened
if necessary.
The grease fitting for the front drive pins faces inboard to prevent
interference with the drag link.
SUSPENSION LUBRICATION
Each standard spring anchor pin has a grease fitting. Pressure lubricate
spring pins as specified. See Recommended Maintenance Schedules,
page 315-342:
• At regular service intervals, the spring leaves may be lubricated
with 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.
Do not spray the suspension with chemical products or mineral oil.
It can cause damage to the bushings.
