Inner Universal Joint Driver W/Differential Bearing Housings

TO REMOVE
Remove the bolts for the differential bearing housing and use puller 87 90 776 and slide hammer 83 90 270 to remove the housing together with the universal joint driver. Save the shims.





TO DISMANTLE
1. Remove the circlip from the universal joint driver.
2. Press the universal joint driver out of the differential bearing housing.
3. Use a screwdriver to remove the seal, but take care not the damage the bearing housing.
4. Remove the speedometer drive from the left-hand bearing housing.





5. Use sleeve 78 41 067 to press out the ball bearing.





6. Use a suitable drift to remove the differential bearing races. The right-hand differential bearing housing (without speedometer drive) includes a washer on the inside of the bearing race, the function of which is to improve the lubrication of the ball bearing.
7. Remove the 0-ring from the bearing housing groove.

TO ASSEMBLE
1. Use sleeve 78 41 141 to press the ball bearing into the bearing housing.





2. Guide the oil catcher washer into its grove in the right-hand bearing housing and use sleeve 83 90 114 to press in the bearing race.





3. Use drift 87 90 800 to press in the seals so that they will be about 2 mm above the face of the bearing housing.
4. Adjust the bearing preload and the backlash. Refer to "Differential, Manual Transaxle/Adjustments/To Adjust the Differential Bearings". Adjustments This applies only to the right-hand side.

6. Use circlip pliers to fit the circlip.
7. Fit the speedometer drive.
8. Fit the 0-ring into the groove in the bearing housing.

TO FIT
For particulars of adjustment of the differential bearing preload and adjustment of the backlash, refer to "Differential, Manual Transaxle/Adjustments/To Adjust the Differential Bearings". Adjustments

1. Ensure that the 0-ring is fitted to the bearing housing and fit the spring with plunger into the hole in the driver shaft end.





2. Fit the measured combination of shims to the two bearing housings and fit the housings, together with the inner universal joint drivers, to the gearcase.
Apply thread sealing compound to the threads of the 12 bolts.
3. While tightening the bearing housings, check that there is backlash in the gear teeth. Tighten the bolts to the specified torque
Tightening torque for the differential bearing housings:
^ 23 - 28 Nm (17 - 21 lb ft)
4. Check the backlash by measuring at four places.
