Maintenance
•
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 should be used for optimal grease distribution
within each component joint.
Refer
to
the
LUBRICATION
AND
MAINTENANCE
INTERVAL CHART and the LUBRICANT AND SEALER
SPECIFICATIONS CHART at the end of this section for
additional information.
•
Inspect,

at regular intervals.
Refer to LUBRICATION AND

Front Axle – Normal Maintenance
During operation the air and oil inside the hub / wheel cavity
expands. It is normal for a mist of oil to be present on the outside
of the hubcap around the vent slit or hole. Over time, if not wiped
off, this film may collect dust and appear unsightly. If the entire
face and end of the hubcap become wet with oil, investigate the
cause. Refer to the Service Manual for repair procedure.
Routinely clean the hubcap to ensure that the lube level can
be easily observed through the clear window as intended.
In situations where the window is clean on the outside but
discolored on the inside, check the lube level by removing the
rubber fill / vent plug and insert a finger into the hole.
The specified lube level for clear window type hubcaps is from
the minimum line to 8 mm (5/16 in) above the minimum line.
If the lube level suddenly drops dramatically below the minimum
level, see the Service Manual for diagnostic procedure.
Front Axle – Alignment
Maintaining front axle alignment is very important to achieve
maximum tire life and vehicle control. Inspecting steer axle tires
in the first 3,000 to 10,000 service miles will generally show if
tires are wearing normally.
•
Rapid outside shoulder wear on both tires indicates too
much toe-in.
•
Rapid inside shoulder wear on both tires indicates too much
toe-out.
•
Excessive wear on the inside or outside of one steer tire
but not the other can indicate a toe-in or toe-out condition
coupled with a misaligned front or rear axle.
•
Pulling to the right or left can indicate misalignment of the
front or rear axle, unequal tire pressures, or a defective /
mismatched tire.
Refer to the TIRES subsection for additional related information.
Rear Axle – Inspection and Lubrication
Make sure the axle mounting U-bolt nuts, and attaching or
mounting bolts and nuts are securely tightened.
Loose or
misaligned rear axles will affect vehicle alignment, front tire
