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 O-ring.
5. Remove oil seal with a screwdriver.
Do not reuse oil seal once it is removed.
Always install new one.
6. Remove ABS sensor rotor. Ð Models with ABS Ð

Inspection
AXLE SHAFT
Check axle shaft for straightness, cracks, damage, wear or distor-
tion. Replace if necessary.
BEARING CAGE
Check bearing cage for deformation or cracks. Replace if neces-
sary.
REAR AXLE HOUSING
Check rear axle housing for yield, deformation or cracks. Replace
if necessary.
Installation
1. Press new wheel bearing until it bottoms end face of bearing
cage.
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 multi-
purpose grease.
3. Install bearing spacer with chamfer side facing axle shaft
¯ange.
4. Install caliper adapter and baffle plate to bearing cage.
5. Press axle shaft into inner race of wheel bearing.
Be careful not to damage or deform grease seal.

6. Install a new wheel bearing lock washer.
7. Tighten wheel bearing lock nut to speci®ed torque.
: 441 - 490 Nzm (45 - 50 kg-m, 325 - 362 ft-lb)
Be sure to bend bearing lock washer up.
8. 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 at left) and
pull it at a speed of 10 rpm to measure preload.
Spring gauge indication:
8.8 - 42.2 N (0.9 - 4.3 kg, 2.0 - 9.5 lb)
9. Install new oil seal to rear axle housing using a suitable tool.
After installing new oil seal, coat sealing lip with multi-purpose
grease.
10. Install new O-ring to rear axle housing.
11. Press ABS sensor rotor onto axle shaft until it contacts wheel
bearing lock nut.
12. Install axle shafts in rear axle housing.
Be careful not to damage oil seal.
