Disassembly and Assembly

DISASSEMBLY
Wheel Bearing

CAUTION: Do not disassemble if wheel bearing has no trouble.
1. Remove wheel bearing fixing bolts and anchor block fixing nuts inside axle vehicle, and remove wheel hub and bearing assembly, back plate and anchor block from axle.

2. Using a drift (special service tool) and a puller (suitable tool), press wheel hub out to remove from wheel bearing.

3. Using a drift (special service tool) and a puller (suitable tool), press wheel bearing outer side inner race out to remove from wheel hub.

Bushing

^ Using a suitable drift, remove each bushing from axle.

INSPECTION AFTER DISASSEMBLY
Wheel Hub
^ Inspect wheel hub for deformation, cracks, and other damage. If any irregular conditions are found, replace wheel hub.

Axle
^ Inspect axle for deformation, cracks, and other damage. If any irregular conditions are found, replace axle.

Back Plate
^ Inspect back plate for deformation, cracks, and other damage. If any irregular conditions are found, replace back plate.

ASSEMBLY
Bushing

^ Using a suitable drift to install each bushing onto axle.

Wheel Bearing

1. Press fit a wheel hub into wheel bearing with a drift (special service tool).

CAUTION:
^ Press fit a drift (special service tool) while holding it against wheel bearing inner side inner race.
^ Wheel bearing cannot be reused. Do not attempt to reuse it.

NOTE: Final press load guideline 49,033 N (5,000 kg, 11,000 lbs.)

2. Install back plate and wheel hub and bearing assembly.
3. Install anchor block onto axle.

INSPECTION AFTER ASSEMBLY
1. With wheel bearing pressed into axle housing, apply 49,033 N (5,000 kg, 11,000 lbs.) to wheel hub and rotate both clockwise and counterclockwise 10 times to minimize resistance.

2. Attach spring scale in the position shown in illustration and pull at a rate of 10 ± 2 rpm to measure rotating torque.
Standard value Rotating torque: Less than 1.88 Nm (0.19 kg-m, 17 inch lbs.)
Spring scale reading: Less than 18.5 N (1.89 kg, 4.16 lbs.)
