Axles
Front Axle
Inspection and Lubrication
Check to make sure that the front axle mounting U-bolts,
attaching or mounting bolts, and nuts are securely tightened.
Loose or misaligned front axles will affect vehicle alignment,
front tire wear, and handling.
Re-torque the U-bolt nuts after the first 1,000 miles (1,600 km)
and every 36,000 miles (58,000 km) thereafter.
Observe the following when checking the front axle for damaged,
binding, or worn parts, and adequate lubrication:
• Kingpin wear inspection requires that no weight is on the
tires.
• Kingpin and kingpin bushing lubrication requires that the
vehicle weight is off tires and the front wheels be turned
fully to the left or right prior to installing grease distribution.
• Kingpin thrust bushing lubrication requires that the vehicle
weight is resting on the tires.
• Power grease guns may be used; however, a
hand-pumped grease gun is recommended for optimal
grease distribution within each component joint.
• Inspect, lubricate and adjust the wheel bearings at regular
intervals.
Refer to SECTION 8 — MAINTENANCE
INTERVALS AND SPECIFICATIONS for the correct
intervals, lubricants, and torques.
