REMOVAL
Refer to the illustration when servicing.
- Remove wheel bearing lock nut.





- Separate drive shaft from axle housing by lightly tapping it. If it is hard to remove use puller. When removing drive shaft, cover boots with shop towel to prevent them from being damaged.





- Remove brake caliper assembly and rotor Brake line need not be disconnected from brake caliper. careful not to depress brake pedal, or piston will pop out. Do not pull or twist brake hose.

Fig. 6 Rear Axle Removal.:





- Remove axle housing.





DISASSEMBLY

Wheel Bearing
1. Remove wheel hub from axle housing using a suitable tool.





2. Remove inner race from hub using a bearing replacer/puller.





3. Remove grease seals from axle housing.





4. Remove snap rings.





5. Press out bearing outer race.

CAUTION: Do not reuse old inner race although it is of the same brand as the bearing assembly.





Axle Housing
1. Attach a drift on outer shell of bushing as shown, remove bushing using arm bushing remover.

NOTE: When placing axle housing in a vise, use wooden blocks or copper plates as pads.





2. Ensure axle housing bore is free from scratches or deformities before pressing bushing into it.
3. Attach bushing to chamfered bore end of axle housing and press it until it is flush with end face of axle housing.





4. When installing shock absorber bushing, make sure that it is positioned as shown.

INSPECTION
- Check wheel hub and axle housing for cracks by using a magnetic exploration or dyeing test.
- Check wheel bearing for damage, seizure, rust or rough operation.
- Check rubber bushing for wear or other damage.
- Check snap ring for wear or cracks.
- Replace as necessary.

ASSEMBLY





1. Install snap ring into groove of axle housing.





2. Press new wheel bearing assembly into axle housing. Press only on outer race of wheel bearing assembly. Maximum load P is 29 kN (3 ton, 3.3 US ton).

CAUTION:
- Do not press inner race of wheel bearing assembly.
- Do not apply oil or grease to mating surfaces of wheel bearing outer race and axle housing.
- Before pressing, check for correct bearing grease seal orientation, as inner and outer seals are different.





3. Install snap ring.





4. Pack grease seal lip with multi-purpose grease.





5. Install outer grease seal.





6. Press wheel hub into axle housing with suitable tool. Maximum load P is 29 kN (3 ton, 3.3 US ton).

CAUTION: Be careful not to damage grease seal.





7. With wheel hub pressed into axle housing, apply 49,000 N (11,000 lbs.) to wheel hub and rotate both clockwise and counterclockwise 10 times to minimize resistance. Attach spring scale in the position shown and pull at a rate of 10 RPM to measure rotating torque.
Load: 49,000 N (11,000 lbs.)
Rotating torque: 0.2 - 2.4 Nm (2.0 - 21.1 inch lbs.)
Spring scale reading: 2.0 - 20.6 N (0.4 - 4.6 lbs.)
8. If measured value is outside specifications, replace wheel bearing. Also make sure axial play does not exist in wheel hub when a 49,000 N (11,000 lb) load is applied.





9. Install inner grease seal.

INSTALLATION

NOTE: When installing rubber parts, final tightening must be carried out under unladen condition with Urea on ground. Fuel, radiator coolant and engine all full. Spare tire, jack, hand tools and mats in designated positions.

- Install axle housing with wheel hub.





- Before tightening bearing lock nut, apply oil to threaded portion of rear spindle and both sides of plain washer and torque to 206 - 275 Nm (152 - 203 ft. lbs.).





- Check wheel bearing axial end play. Axial end play is 0.05 mm (0.0020 inch) or less.
- Make sure that wheel bearings operate smoothly
- Check toe in.
