15. Measure the rotating torque of the pinion using an inch-pound torque wrench.
Specification: The rotating torque of the pinion should be 1.0-2.3 N.m (10-20 lb in) for
used bearings, or 1.7-3.4 N.m (15-30 lb in) for new bearings.
16. If the rotating torque measurement is below 1.0 N.m (10 lb in) for used bearings, or 1.7 N.m
(15 lb in) for new bearings, reinstall the J 8614-01 and continue to tighten the pinion nut.
See Special Tools.
Specification: The rotating torque of the pinion should be 1.0-2.3 N.m (10-20 lb in) for
used bearings, or 1.7-3.4 N.m (15-30 lb in) for new bearings.
17. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings
have seated.
Recheck the rotating torque and adjust if necessary.
18. Remove the J 8614-01 . See Special Tools.
19. Assemble the right side differential adjuster nut into the differential nut sleeve until fully
