975 Inch, 105 Inch Axles - Pinion Bearing Service and Repair
16. Install the J18614-01 onto the pinion yoke as shown.
Notice: Refer to Fastener Notice in Service Precautions.
Important: If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.
17. Tighten the pinion nut while holding the J8614-01.
Tighten the pinion nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings.
18. 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.
19. 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.
20. 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.
21. Install the differential assembly.
22. Fill the axle with the proper axle lubricant.
23. Lower the vehicle.
