9-7X V8-5.3L (2005)
1. Install the new deflector onto the pinion yoke using a soft-faced hammer.
Important: Drive the seal in straight, not at an angle, as this will damage the aluminum housing.
2. Install the new oil seal by doing the following:
1. Position the oil seal in the bore.
2. Install the J 33782 over the oil seal.
3. Strike the J 33782 with a hammer until the seal flange seats on the axle housing surface.
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.
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.
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.
6. Install the washer and a new pinion nut.
7. Install the J 8614-01 onto the pinion yoke as shown.
Notice: Refer to Fastener Notice.
Important: If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.
8. Tighten the pinion nut while holding the J 8614-01.
Tighten the pinion nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings.
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 in. 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 in.
lbs.) greater than the torque recorded during removal.
