10. Using an inch-pound torque wrench, measure the rotating torque of the drive pinion should be between 1.0-2.3 Nm (10-20 lb in) for used bearings
and 1.7-3.4 Nm (15-30 lb in) for new bearings.
11. 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 in small increments, as needed, until the desired rotating torque specifications are reached as indicated in steps 10 and 11.
12. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings have seated.
13. Recheck the rotating torque and adjust if necessary.
14. Install the differential assembly. Refer to Differential Replacement .
15. Fill the axle with lubricant. Use the proper fluid. Refer to Differential Oil Replacement .
