Side Bearing Preload
SIDE BEARING PRELOADNOTE: A selection of carrier side bearing adjusting washers are required for successful completion of this procedure.
1. Make sure all parts are clean and that the bearings are well lubricated with light oil or "DEXRON TM " automatic transmission fluid or equivalent.
2. Place the differential carrier assembly, with side bearings and bearing races installed, into the final drive housing.
3. Put the side bearing spacer in place.
CAUTION: Side bearing spacer is placed on either the right or left depending upon final drive gear ratio. Be sure to replace it on the correct side.
4. Install original side bearing adjusting shims on the differential case assembly end, opposite the ring gear using Tool.
Tool number: KV38100600 (J25267)
5. Install the side bearing caps in their correct locations and tighten the bearing cap bolts.
Bearing cap: 88 - 98 Nm (9 - 10 kg-m, 65 - 72 ft. lbs.) bolts
6. Turn the differential case assembly several times to seat the bearings.
7. Measure the differential case assembly turning resistance at the ring gear bolts using Tool.
Differential case assembly turning resistance of pulling force at the ring gear bolt: 34.3 - 39.2 N (3.5 - 4.0 kg, 7.7 - 8.8 lbs.)
Tool number (J8129)
8. If the differential case assembly turning resistance is not within the specification range, increase or decrease the total thickness of the side bearing adjusting shims until the turning resistance is correct. If the turning resistance is less than the specified range, install side bearing adjusting shims of greater thickness; if the turning resistance is greater than the specification, install thinner side bearing adjusting shims. Refer to "Side Bearing Adjustment".
9. Record the total amount of side bearing adjusting shim thickness required for the correct side bearing preload.
10. Remove the differential case assembly from the final drive housing, saving the selected side bearing adjusting shims for later use during the assembly of the final drive unit.
