Removal

1. Raise the vehicle.

2. Remove the rear wheel.

3. Remove the brake caliper.

4. Remove the gearbox housing cover and cover gasket.

5. Loosen the differential drive gear axle fixing bolt.



6. On models without a locking differential, remove the pinion shaft.



7. On models with a locking differential, partially extend the pinion shaft from the differential cup. Rotate the differential cup until the pinion shaft stops in the gear housing.



8. On models with a locking differential, use a screwdriver to rotate the locking ring (1) until it aligns with the thrust block (2).





9. Push the axle shaft flange (1) towards the differential until the retaining ring comes out of the thrust block.



10. Remove the retaining rings (4) from the end of the axle shaft (1).

11. Remove the axle shaft (1) from the rear axle beam (5).

Caution: When removing the axle shaft, do not rotate the axle shaft. Rotating the axle shaft will cause the differential gears to become misaligned, making subsequent assembly difficult.
