WHEEL BEARING PLAY CHECK

M1261001100094

1. Remove caliper assembly and suspend it with wire to

prevent it from falling.

2. Remove brake disc from hub.
3. Set dial gauge as shown in the diagram and move hub in the

axis to measure backlash.

Limit: 0 mm (0 inch)

4. If the play exceeds the limit value, disassemble hub knuckle

to check each component. If the front hub assembly bearing
is faulty, replace the front hub assembly.

FRONT AXLE TOTAL BACKLASH CHECK

M1261001300087

When the ignition switch is in "LOCK" (OFF) position, the front
wheel comes to a stop after turning the propeller shaft by hand
due to the force applied to front wheel actuator. Inspect the
vehicle as follows:
1. Turn the ignition switch to "LOCK" (OFF) position, and then

put the transfer shift lever to the "2H" position.

2. Turn the propeller shaft until a click is heard.
3. Turn the companion flange clockwise until all play is

eliminated, and then align the mating mark on the dust cover
with the mating mark on the differential carrier.

4. Turn the companion flange counterclockwise until all play is

eliminated and measure the distance through which the
mating marks moved.

Limit: 11 mm (0.4 inch)

5. If the amount of movement exceeds the limit value, check

the following.

• Final drive gear backlash

• Differential gear backlash

• Play in the serrations and splines of the side gears, drive

shaft, and drive flange

FRONT AXLE GEAR OIL LEVEL CHECK
