17. Measure the rotating torque of the pinion using an inch-pound torque wrench.
The rotating torque of the pinion should be between 1.0-2.3 Nm (10-20 inch lbs.) for used bearings, or 1.7-3.4 Nm (15-30 inch lbs.) for new
bearings.
18. If the rotating torque measurement is below 1.0 Nm (10 inch lbs.) for used bearings, or 1.7 Nm (15 inch lbs.) 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 between 1.0-2.3 Nm (10-20
inch lbs.) for used bearings, or 1.7-3.4 Nm (15-30 inch lbs.) for new bearings.
19. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings have seated. Inspect the rotating torque and adjust if
necessary.
20. Install the differential assembly.
21. Fill the axle with lubricant. Use the proper fluid.
22. Lower the vehicle.
