Dismantling
1. Remove the rear axle drive shaft housing.

TRANSFER BOX, REPAIRS, Rear Axle Drive Shaft Seal: vehicles with KV6 engine except North American market.
TRANSFER BOX, REPAIRS, Rear axle drive shaft oil seal: cars with KV6 engine, for North American market countries.
ATTENTION: Before removing the rear axle drive shaft housing, measure the resistance to its rotation in the bearings.
2. Attach the rear axle drive shaft housing to the rig and secure the rig in a vise.
3. Compare the resistance to rotation with that obtained earlier.
4. To facilitate reassembly, mark the mounting marks on the rear axle drive shaft and on the shaft flange.
5. Fix the rear axle drive shaft flange with tool LRT-51-003.
6. Loosen and discard the nut.
7. Install the rear axle drive shaft housing on the press, place a mandrel on the end of the shaft and press the shaft out of the flange and out of the housing.
8. Remove and discard deformable spacer.
9. Using a lever, remove the rear axle drive shaft seal.
CAUTION: Be careful not to damage the gland seat.
10. Remove the bearing from the rear axle drive shaft.
Installation
1. Clean the rear axle drive shaft, shaft flange and shaft housing.
2. Wash the stuffing box seat.
3. Lubricate the bearing and install it in the shaft housing.
4. Lubricate the new oil seal.
5. Using a mandrel, press the stuffing box into the shaft housing seat.
CAUTION: The oil seal must be installed flush with the lip of the rear axle drive shaft housing.
6. Insert the shaft into the shaft housing using a new deformable spacer.
7. Apply a thin coat of molybdenum disulphide grease to the shaft flange splines.
8. Align the marks on the shaft with the marks on the flange and press the flange onto the shaft so that there is a gap of 2 mm between the bearings.
9. Attach the assembled assembly to the rig and secure the rig in a vise.
10. Fit a new nut, holding the flange with tool LRT-51-003 and tighten the nut to 150 Nm.
11. Compare the resistance to rotation with that obtained earlier.
NOTE: Rotational resistance on new bearings is 180 to 200 Ncm.
If the resistance on the old bearings was higher than 20-30 N-cm and lower than on the new ones, then the resistance must be adjusted to the previously recorded value.
If the resistance to rotation on the old bearings was below 20 N cm, then the resistance must be adjusted to 20-30 N cm.
12. If the resistance to rotation is too low, then carefully tighten the nut and measure the resistance again. If the resistance to rotation is too great, the assembly must be disassembled and reassembled with a new deformable spacer. Reassembly is done with a new nut. Re-measure the resistance to rotation.
13. Check flange runout using a dial gauge.
ATTENTION: The runout of the flange must not exceed 0.05 mm.
14. Remove the tool from the vise and remove the assembled assembly from the tool.
15. Install the rear axle drive shaft housing.
