4. MAINTENANCE
A periodic inspection of the front axle assembly
should be made to check that no damage and
distortion have taken place. All the bolts and and
stop screws should be checked and tightened,
as required, to the torque specifications given at
the beginning of this section. Also check the
condition of the steering knuckle kingpins and
bushings. In case of excessive looseness, the
bushings and kingpins should be replaced.
Any looseness in the steering linkage, under
normal steering loads, is sufficient cause to
immediately check all pivot points for wear,
regardless of accumulated mileage. Steering
linkage pivot points should be checked each time
the front axle assembly is lubricated. Any
looseness can be visually detected while rotating
the steering wheel in both directions.
Steering knuckles, knuckle pins and bushings can
be overhauled or replaced without removing the
axle from the vehicle. However, if extensive
overhaul work is necessary, the axle assembly
should be removed.
CAUTION
Should removal of a locking device be required
when undergoing repairs, disas
sembly or
adjustments, always replace with a new one.
