DIFFERENTIAL SIDE BEARING PRELOAD ADJUSTMENT
1. Set the differential assembly to the clutch housing assembly.
2. Push and fit the tapered roller bearing outer race by hand.
3. To fit the tapered roller bearing outer race, rotate the differential assembly by hand about 10 times.
4. Put the clutch housing assembly on the flat table and use a height gauge to measure the dimension "A" between the mating surface of the clutch housing assembly and the end surface of the tapered roller bearing outer race.
5. Put a straight edge on the mating surface of the transaxle case assembly and measure the dimension "B" with a vernier caliper.
6. Select the shim whose dimension is the difference between "B" and "A."
7. Insert a wedge between the side gear and the pinion shaft to lock the side gear.
8. Install the differential assembly to the clutch housing assembly. Tighten the transaxle case bolts to the specified torque.Tightening torque: 30 ± 5 N·m (22 ± 3 ft-lb)
9. Using special tool Side gear holding tool (MB991144), measure the rotational starting torque of differential case. When it is not within the standard range, reselect the shim.Standard value:
- Used part: 0.5 - 1.0 N·m (4 - 9 in-lb)
- New part: 0.8 - 1.6 N·m (7 - 14 in-lb)
