1. Front Wheel Bearing
Inspection
Inspect the wheel hub bearings for excessive
play as follows:
1. Raise the vehicle and support the front
axle on jack stands.
2. Ensure the brakes are released and the
wheels can rotate freely.
1.1. Disc Brakes (VOK-07-F)
1. Attach the base of a magnetic dial gauge
to any part of the steering knuckle. See
“Fig. 1: Wheel Bearing Inspection” on
page 2.
2. Align the dial gauge pin perpendicular to
the face of the brake rotor and as close as
possible to the outer edge of the brake
disc. Also ensure that the dial gauge pin is
located at either the 6 o’clock or 12 o’clock
position.
☞NOTE:
It is important that the dial gauge pin be
positioned at the correct distance from the
center of the brake disc in order to obtain
an accurate reading. The tip of the gauge
should be resting approximately 8.25 to
8.5″ (210 to 215 mm) from the center of the
disc.
3. Zero the dial gauge.
4. Grasp the wheel at the top and bottom and
rock back and forth while observing the
dial indicator reading.
☞NOTE:
If clearance issues resulted in the dial
gauge being positioned somewhere other
than the 12 o’clock or 6 o’clock position,
then ensure the wheel is grasped at a location
that corresponds to the dial gauge. As
an example, if the dial gauge was located
at the 2 o’clock position, then grasp the
wheel at the 2 o’clock and 8 o’clock positions
and rock back and forth.
If total movement exceeds 0.010″ (0.25
mm). Replace the wheel hub as an assembly.
☞NOTE:
The wheel hub is a unitized assembly and
has no replaceable components.

1.2. Drum Brakes (V8-65L)
1. Attach the base of a magnetic dial gauge
to any part of the steering knuckle. See
“Fig. 2: Wheel Bearing Inspection” on
page 3.
2. Align the dial gauge pin perpendicular to
the face of the brake drum with the dial
gauge pin resting on the rim of the brake
drum. Also ensure that the dial gauge pin
is located at either the 6 o’clock or 12
o’clock position.
3. Zero the dial gauge.
4. Grasp the wheel at the top and bottom and
rock back and forth while observing the
dial indicator reading.
☞NOTE:
If clearance issues resulted in the dial
gauge being positioned somewhere other
than the 12 o’clock or 6 o’clock position,
then ensure the wheel is grasped at a location
that corresponds to the dial gauge. As
an example, if the dial gauge was located
at the 2 o’clock position, then grasp the
wheel at the 2 o’clock and 8 o’clock positions
and rock back and forth.
If total movement exceeds 0.010″ (0.25
mm). Replace the wheel hub as an assembly.
☞NOTE:
The wheel hub is a unitized assembly and
has no replaceable components.

2. Rear Wheel Bearing
Inspection
Inspect the wheel hub bearings for excessive
play as follows:
1. Raise the vehicle and support the rear axle
on jack stands.
2. Ensure the brakes are released and the
wheels can rotate freely.
2.1. Disc Brakes
(HY-1336-F, HY-1350-F))
1. Attach the base of a magnetic dial gauge
to any rigid part of the vehicle structure or
axle housing. See “Fig. 3: Wheel Bearing
Inspection” on page 4.
2. Align the dial gauge pin perpendicular to
the face of the brake rotor and as close as
possible to the outer edge of the brake
disc. Also ensure that the dial gauge pin is
located at either the 6 o’clock or 12 o’clock
position.
☞NOTE:
It is important that the dial gauge pin be
positioned at the correct distance from the
center of the brake disc in order to obtain
an accurate reading. The tip of the gauge
should be resting approximately 8.25 to
8.5″ (210 to 215 mm) from the center of the
disc.
3. Zero the dial gauge.
4. Grasp the wheel at the top and bottom and
rock back and forth while observing the
dial indicator reading.
☞NOTE:

gauge being positioned somewhere other
than the 12 o’clock or 6 o’clock position,

that corresponds to the dial gauge. As
an example, if the dial gauge was located
at the 2 o’clock position, then grasp the
wheel at the 2 o’clock and 8 o’clock positions
and rock back and forth.
If total movement exceeds 0.010″ (0.25
mm). Replace the wheel hub as an assembly.
☞NOTE:
The wheel hub is a unitized assembly and
has no replaceable components.
