Overhaul

Removal

CAUTION:
- Before removing the rear axle, disconnect the ABS wheel sensor from the assembly. Then move it away from the axle. Failure to do so may result in damage to the sensor wires and the sensor becoming inoperative. Wheel bearing does not require maintenance.
- If growling noise is emitted from wheel bearing during operation, replace wheel bearing assembly.
- If the wheel bearing assembly is removed, it must be renewed. The old assembly must not be re-used.





1. Disconnect parking brake cable and brake tube.
2. Remove nuts securing wheel bearing cage with baffle plate.





3. Draw out axle shaft with Tool.
When drawing out axle shaft, be careful not to damage oil seal.





4. Remove oil seal with a screwdriver. Do not reuse oil seal once it is removed. Always install new one.
5. Remove ABS sensor rotor.





6. Unbend lock washer with a screwdriver. Do not reuse lock washer once removed. Always install new one.





7. Remove bearing lock nut with Tool.





8. Remove wheel bearing together with bearing cage and baffle plate from axle shaft.
9. Remove grease seal with a screwdriver.





10. Remove wheel bearing assembly with a brass drift.

Inspection
AXLE SHAFT
Check axle shaft for straightness, cracks, damage, wear and distortion. Replace if necessary.

BEARING CAGE
Check bearing cage for deformation and cracks. Replace if necessary.

REAR AXLE HOUSING
Check rear axle housing for yield, deformation and cracks. Replace if necessary.

Installation





1. Press new wheel bearing until it bottoms end face of bearing cage.
Maximum load P: 39 kN (4 ton, 4.4 US ton, 3.9 Imp ton)
Always press outer race of wheel bearing during installation.





2. Press new grease seal until it bottoms end face of bearing cage.
After installing new grease seal, coat sealing lip with multipurpose grease.





3. Press axle shaft into inner race of wheel bearing.
Maximum load P: 47.1 kN (4.8 ton, 5.3 US ton, 4.72 Imp ton)
Be careful not to damage and deform grease seal.





4. Install plain washer and a new wheel bearing lock washer.
5. Tighten wheel bearing lock nut to specified torque.
245 - 314 Nm (25 - 32 kg-m, 181 - 231 ft. lbs.)
Fit wheel bearing lock washer lip in wheel bearing lock nut groove correctly by tightening lock nut. Be sure to bend it up.





6. Check wheel bearing preload.
a. Turn bearing cage (with respect to axle shaft) two or three times. It must turn smoothly.
b. Attach spring gauge to bearing cage bolt (as shown) and pull it at a speed of 10 rpm to measure preload. Spring gauge indication:
6.9 - 48.1 N (0.7 - 4.9 kg, 1.5 - 10.8 lb)





7. Install new oil seal to rear axle housing using a suitable tool.
After installing new oil seal, coat sealing lip with multipurpose grease.





8. Press ABS sensor rotor onto axle shaft until it contacts wheel bearing lock nut.
9. Position axle shafts in rear axle housing with Tool as a guide.
Be careful not to damage oil seal.





10. Check axial end play.
a. Check that wheel bearings operate smoothly.
b. Check axial end play.
Axial end play: 0 mm (0 inch)
