Specification: The rotating torque of the drive pinion should be 1.7-3.4 N.m (15-30 lb in) 3. If the rotating torque for the drive pinion bearings is not within specifications, adjust as necessary. Refer to Drive Pinion and Ring Gear Replacement. 4. Install the differential assembly with the differential side bearings and differential side bearing cups into the axle housing. 5. Insert one 4.318 mm (0.170 in) thick service spacer into the left side of the axle housing. 6. Side the differential assembly towards the service spacer in order to hold the spacer in place. 7. Install the J 22779 into the right side of the axle housing. The J 22779 must be installed between the service spacer and the differential side bearing 8. Tighten the knob on the J 22779 until there is moderate drag when the J 22779 is moved. 9. Remove the J 22779 . 10. Remove the service spacer. 11. Using a micrometer, measure the thickness of the service spacer. Record the measurement. 12. Using a micrometer, measure the thickness of the J 22779 in 3 locations. Calculate the average of the 3 measurements. Record the measurement. 13. Add the thickness of the service spacer, measured in Step 11 to the average thickness of the J 22779 , measured in Step 12. The resulting value is the total service shim thickness 14. Insert one BENT 1.016 mm (0.040 in) service shim between the right side differential side bearing cup and the axle housing. The service shim must be installed between the service IMPORTANT: Before installation of the differential assembly, ensure that the differential side bearing surfaces in the axle housing are IMPORTANT: Over-tightening of the J 22779 may spread the housing and result in incorrect shim selection.
