INFOID:0000000009478709

CAUTION:

Before removing the rear axle, disconnect the 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 replaced. The old assembly must not be re-used.

15. Remove the wheel studs using a suitable hammer or press.
16. Remove the grease catcher from the axle shaft.

INSPECTION AFTER REMOVAL

Axle Shaft

• Check axle shaft for straightness, cracks, damage, wear and distortion. Replace if necessary.

Axle Case

• Check axle case for yield, deformation and cracks. Replace if necessary. Refer to 

DLN-225, "Disassembly

and Assembly"

.

INSTALLATION

1. Install the grease catcher on the axle shaft.
2. Install the wheel studs through the grease catcher into the axle shaft using a suitable press.

NOTE:

All six wheel studs must be pressed on at the same time and are flush with the grease catcher when

installed.

3. Position the axle bearing on the back plate and torque member.
4. Install the axle bearing studs using a suitable press to attach the axle bearing to the back plate and torque

member.

CAUTION:

Do not reuse the axle bearing.

5. Install the back plate and torque member, new axle bearing and

new bearing ring retainer on the axle shaft using a suitable

press.

CAUTION:

• Press the new bearing ring retainer on the axle shaft with

the taper side positioned as shown. 

• Do not reuse the bearing ring retainer.

6. Select the correct size shim washer. Refer to 

RAX-14, "Shim Washers"

.

• Select the size of shim washer so that the installed snap ring to shim washer clearance is within specifi-

cation.

7. Install a new snap ring on the axle shaft.

• Do not over spread the snap ring when installing, measure the outer diameter of the snap ring after

installation and replace if the snap ring outer diameter exceeds specification.

CAUTION:

Maximum press load “P1”

: 98 kN (10 ton, 11.0 US 
ton, 9.8 Imp ton)

Do not reuse the snap ring.

8. Check the snap ring to shim washer clearance, repeat steps 7 and 8 as necessary until the installed snap

ring to shim washer clearance is within specification.

9. Perform break-in rotation of the wheel bearing.
a. Rotate the wheel bearing in the forward direction for a minimum of 10 revolutions at 50-70 RPM.
b. Rotate the wheel bearing in the reverse direction for a minimum of 10 revolutions at 50-70 RPM.
10. Measure the rotational torque of the wheel bearing.

11. Inspect that the wheel bearing is free from axial play relative to the axle shaft.
12. Install a new wheel sensor rotor on the axle shaft using a suit-

able press.

CAUTION:

• Press the new wheel sensor rotor on the axle shaft with

the notch side positioned as shown.

• Do not reuse the wheel sensor rotor.
