Side Bearing Preload

SIDE BEARING PRELOAD
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.
2. Place the differential carrier, 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. Using Tool, install original carrier side bearing preload shims on the carrier end, opposite the ring gear.

Tool number: KV38100600 (J25267)






5. Install the side bearing caps in their correct locations and torque the bearing cap retaining bolts.

Specification:...................88 - 98 Nm (9 - 10 kg.m, 65 - 72 ft. lbs.)

6. Turn the carrier several times to seat the bearings.






7. Measure the turning torque of the carrier at the ring gear retaining bolts with a spring gauge, J8129.

Specification:......................34.3 - 39.2 N (3.5 - 4.0 kg, 7.7 - 8.8 lbs.) of pulling force at the ring gear bolt






8. If the carrier turning torque is not within the specification range, increase or decrease the total thickness of the side bearing adjusting washers until the turning torque is correct.

Side Bearing Adjustment / R200A - Front Final Drive:

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.

9. Record the total amount of washer thickness required for the correct carrier side bearing preload.






10. Remove the carrier from the final drive housing, saving the selected preload washers for later use during the assembly of the final drive unit.
