Section 10: FRONT AXLE
PA1593

NOTE
To avoid inaccurate measurements, be careful
not to let the knuckle turn while moving
assembly in and out. Applying brakes will help
lock wheel assembly.
Locate indicator on a smooth, flat surface for
best reading.
5.1.2 Checking Vertical Slackness
1. This is measured by a dial indicator
anchored to axle beam and having its
pointer placed vertical against swivel top.
2. Place a jack against underside of swivel
and, while applying a lifting force, observe
any movement on indicator dial.
3.
If vertical movement is evident and it
exceeds 0.040” (1.02mm)
then readjust-
ment of swivel is required by adjusting
thickness of bearing adjusting washers.
6. FRONT WHEEL ALIGNMENT
Correct front wheel alignment must be maintained
for steering comfort and satisfactory tire life. Road
shocks and vibrations, as well as normal stress
and strains on the front-end system can, under
normal operating conditions, result in loss of front
wheel alignment.
Check the front wheel alignment when the
following occurs:
1. Every 200,000 miles (320 000 km) or 24
months (normal maintenance);
2. When the vehicle does not steer correctly; or
3. To correct a tire wear condition.
There are two types of front wheel alignment:
minor alignment
and
major alignment
.
6.1
INSPECTION BEFORE ALIGNMENT
Check the following before doing a front wheel
alignment:
1. Ensure that the vehicle is at normal riding
height. See Section 16,
‘’Suspension’’
under heading 7:
‘’Suspension Height
Adjustment’’
.
2. Ensure that front wheels are not the cause
of the problem. See Section 13,
‘’Wheels,
Hubs and Tires’’
. Inspect the tires for wear
patterns indicating suspension damage or
misalignment.
a. Make sure the tires are inflated to the
specified pressure.
b. Make sure the front tires are the same
size and type.
c. Make sure the wheels are balanced.
d.
Check wheel installation and
straightness.
3. Check the wheel bearing adjustment.
4. Check steering linkage for bending and
pivot points for looseness.
5. Check knuckle pins for evidence of
excessive wear.
6. Check radius rods for bending and rubber
bushings for evidence of excessive wear.
7. Make sure all fasteners are tightened to the
specified torque. Use a torque wrench for
verification. As soon as the fastener starts
to move, record the torque. Correct if
necessary. Replace any worn or damaged
fasteners.
6.2
MINOR FRONT WHEEL ALIGNMENT
Perform a minor front wheel alignment for all
normal maintenance conditions.
Perform the minor front wheel alignment in the
following sequence :
