Oil seal replacement: 1, 4 - oil deflector, 2 - connecting flange, 3 - oil seal, 5 - filler plug, 6, 7 - gasket, 8 - drain plug, 9 - bearing spacer, 10 - front bearing.
1. Drain the oil from the differential case.
2. Disconnect the cardan shaft from the differential.
Note: Fix the cardan shaft.
3. Remove the connecting flange
- A) Using a chisel and hammer, loosen the nut.
- b) While holding the flange, unscrew the nut.
- V) Using the special tool, remove the connecting flange.
4. Remove the front oil seal and oil deflector.
- A) Using the special tool, remove the seal.
- b) Remove the oil deflector.
5. Remove front bearing and spacer
- A) Using the special tool, remove the front bearing.
- b) Remove the spacer sleeve.
6. Install a new spacer and front bearing.
- A) Install a new spacer onto the shaft.
- b) Install the front bearing onto the shaft.
7. Install the oil deflector and a new oil seal.
- A) Install the oil deflector.
- b) Using the special tool, install a new oil seal. Installation depth 2.0 mm.
- V) Apply grease to the seal lip.
8. Install the connecting flange,
- A) Using the special tool, install the connecting flange onto the shaft.
- b) Apply grease to the threads of the new nut.
- V) While holding the flange, tighten the nut. Tightening torque 108 Nm.
- G) Adjust the pinion bearing preload. Using a torque wrench, measure the final drive pinion bearing preload. Bearing preload:
- New: 1.0-1.6 Nm.
- Used: 0.5-0.8 N.m
If the preload is greater than the maximum allowable, replace the spacer.
If the preload is less than the maximum allowable, tighten the nut at small angles (increasing the tightening torque by 13 Nm) until the preload matches the specified one. If the preload exceeds the maximum allowable when re-tightening the nut, replace the spacer and repeat the adjustment procedure. Do not adjust preload by loosening the nut.
9. Lock the nut.
10. Connect the cardan shaft.
11. Fill the gear oil into the differential.
