Side Bearing Preload

A selection of carrier side bearing adjusting washers is required for successful completion of this procedure.

1. Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2. Place the differential case assembly, with side bearing outer races installed, into the gear carrier.
3. Insert left and right side bearing adjusting washers in place between side bearings and gear carrier.

4. Install the bearing caps in their correct locations and torque the bearing cap retaining bolts. Refer to COMPONENTS .
5. Turn the carrier several times to seat the bearings.

6. Measure the turning torque of the carrier at the drive gear retaining bolts with a spring gauge, J-8129.
   1. Specification :34.2 - 39.2 N (3.5 - 4 kg, 7.7 - 8.8 lb) of pulling force at the drive gear bolt

7. If the turning torque is not within the specifications, correct the torque as follows:
   • If the turning torque is less than the specified range, install washers of greater thickness.
   • If the turning torque is greater than the specification, install thinner washers.
   • See the SERVICE DATA AND SPECIFICATIONS (SDS)  section for washer dimensions and part numbers.
8. Record the total amount of washer thickness required for the correct carrier side bearing preload.
