Silverado 1500 4WD V8-5.3L VIN T (2004)
8. Install a new pinion oil seal using the J 44414.
9. Apply sealant, GM P/N 12346004 (Canadian P/N 10953480) or equivalent, to the splines of the pinion yoke.
10. Install the pinion yoke. Align the marks made during removal.
11. Seat the pinion yoke onto the pinion shaft by tapping it with a soft-faced hammer until a few pinion shaft threads show through the yoke.
Notice:
Do not hammer the pinion flange/yoke onto the pinion shaft. Pinion components may be damaged if the pinion flange/yoke is hammered onto the
pinion shaft.
12. Install the washer and a new pinion nut.
13. Install the J 8614-01 onto the pinion yoke as shown.
14. Tighten the pinion nut while holding the J 8614-01.
^
Tighten the nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings.
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.
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.
