  16. Install the pinion in the pinion gear bearing retainer.
  17. Install the drive pinion flange/yoke. Refer to Drive Pinion Flange/Yoke and/or Oil Seal Replacement 
  18. NOTE:

    Do not apply sealant to the pinion gear bearing retainer at this time.

  19. Install the original shim to the pinion bearing retainer. If the original shim is not available, install a 0.41 mm (0.016 in) shim to build pinion depth.
  20. Install the pinion gear bearing retainer to the axle housing. Refer to Drive Pinion Housing and/or Seal Replacement 
  21. Fig 8: Measuring Pinion Rotating Torque

  22. Using an inch-pound torque wrench, measure the rotating torque of the pinion should be between 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.
  23. 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, use the J 8614-01  holding tool and continue to tighten the pinion nut, in small increments, as needed, until the rotating torque is between 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.
  24. 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.

  25. Install the differential assembly. Refer to Differential Replacement (10.5 Inch Axle) , Differential Replacement (8.6, 9.5/9.5 LD Inch Axles) .
  26. Adjust the differential side bearing preload. Refer to Differential Carrier Bearing Preload Adjustment (8.6 Inch Axle) , Differential Carrier Bearing Preload Adjustment (9.5LD Inch Axle) , Differential Carrier Bearing Preload Adjustment (10.5 Inch Axle) .
  27. Adjust the drive pinion gear pinion depth, if needed. Refer to Pinion Depth Adjustment (9.5LD Inch Axle) , Pinion Depth Adjustment (10.5 Inch Axle) , Pinion Depth Adjustment (8.6 Inch Axle) .
  28. Adjust the backlash. Refer to Backlash Adjustment (10.5 Inch Axle) , Backlash Adjustment (9.5 LD Axle) , Backlash Adjustment (8.6 Inch Axle) .
  29. Fill the axle with lubricant. Refer to Differential Oil Replacement (8.6 Inch Axle) , Differential Oil Replacement (10.5 Inch Axle) , Differential Oil Replacement (9.5LD Inch Axle) .
  30. Remove the support and lower the vehicle.
