Rainier AWD L6-4.2L VIN S (2005)
2. Install the new oil seal by doing the following:
1. Position the oil seal in the bore.
2. Install the J33782 over the oil seal.
3. Strike the J33782 with a hammer until the seal flange seats on the axle housing surface.
Important: Drive the seal in straight, not at an angle, as this will damage the aluminum housing.
3. Apply sealant GM P/N 12346004 (Canadian P/N 10953480) or equivalent to the splines of the drive pinion yoke.
4. Install the pinion yoke. Align the reference marks made during removal.
5. 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.
6. Install the washer and a new pinion nut.
7. Install the J8614-01 onto the pinion yoke as shown.
8. 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.
Notice: Refer to Fastener in Service Precautions.
Important: If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.
9. Measure the rotating torque of the pinion using an inch-pound torque wrench.Compare the measurement of the rotating torque to the measurement
recorded earlier.
The rotating torque of the pinion nut should be 0.40 - 0.57 Nm (3 - 5 inch lbs.) greater than the torque recorded during removal.
10. If the rotating torque is not within specifications, 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 0.40 - 0.57 Nm (3 - 5 inch lbs.)
greater than the torque recorded during removal.
11. 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.
12. Install the rear steering gear crossmember.
13. Install the front propeller shaft.
14. Install the engine protection shield.
15. Inspect the axle lubricant level, and add, if necessary.
16. Lower the vehicle.
