16. Tighten the pinion nut while holding the J 8614-01 .
Tighten the pinion nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings.
17. Measure the rotating torque of the pinion using an inch-pound torque wrench.
The rotating torque of the pinion should be 1.0-2.3 Nm (10-20 lb in) for used bearings, or 1.7-3.4 Nm (15-30 lb in) for new bearings.
18. If the rotating torque measurement is below 1.0 Nm (10 lb in) for used bearings, or 1.7 Nm (15 lb in) for new bearings, continue to tighten the
pinion nut.
Tighten the pinion nut, in small increments, as needed, until the torque required in order to rotate the pinion is 1.0-2.3 Nm (10-20 lb
in) for used bearings, or 1.7-3.4 Nm (15-30 lb in) for new bearings.
19. 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.
20. Install the differential. Refer to Differential Replacement (See: Service and Repair/Removal and Replacement/Rear Drive Axle/Differential
Replacement).
21. Fill the axle with axle lubricant lubricant. Use the proper fluid. Refer to Front Axle Lubricant Replacement (See: Fluid - Differential/Service and
Repair/Removal and Replacement/Front Drive Axle).
22. Lower the vehicle.
