Suburban 1/2 Ton 2WD V8-5.3L VIN T (2004)
15. Measure the rotating torque of the pinion. Compare this measurement with the rotating torque recorded during removal.
^
Tighten the nut in small increments, as needed, until the rotating torque is 0.40 - 0.57 Nm (3 - 5 inch lbs.) greater than the rotating torque
recorded during removal.
16. 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.
17. Determine the selective shim thickness for the pinion gear bearing retainer.
18. Apply sealant, GM P/N 1052942 (Canadian P/N 10953466) or equivalent. to the sealing surface of the pinion gear bearing retainer.
19. Install the selective shim. Align the tab on the shim with the unmachined surface of the pinion gear bearing retainer-.
20. Apply sealant, GM P/N 1052942 (Canadian P/N 10953466) or equivalent, to the surface of the selective shim.
21. Install the pinion gear bearing retainer.
22. Install the pinion gear bearing retainer bolts.
^
Tighten the pinion gear bearing retainer bolts to 88 Nm (65 ft. lbs.).
23. Measure the rotating torque of the pinion and the ring gear. Compare this measurement with the rotating torque recorded during removal.
Specification
^
The rotating torque of the pinion and the ring gear should be between 3.9 - 6.2 Nm (30 - 55 inch lbs.) for new bearings or 2.8-5.6 Nm (25-50
inch lbs.) for used bearings.
24. If the rotating torque of the pinion and the ring gear is not within specifications. adjust the preload of the pinion or the differential side bearings as
necessary.
