Installation Procedure

  1. Install the new pinion oil seal using the J 33782  on the 7.6 inch axles, or the J 22388  on the 8.6 inch axle.
  2. Apply sealant, GM P/N 12346004 or equivalent, to the splines of the pinion yoke.

    Important:  Install the pinion gear flange/yoke to the pinion gear shaft in the same position as marked during removal in order to maintain correct driveline balance.

  3. Install the pinion yoke.

    Align the marks made during removal.

    NOTE: 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.
  4. Seat the pinion flange/yoke onto the pinion shaft by tapping it with a soft-faced hammer until a few pinion shaft threads show through the flange/yoke.
  5. Install the washer and a new pinion nut.
  6. Install the J 8614-01  onto the pinion flange/yoke as shown.
    NOTE: Refer to FASTENER NOTICE in Cautions and Notices.

    Important:  If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.

  7. Tighten the pinion nut while holding the J 8614-01  .

    Tighten 

    Tighten the nut until the pinion end play is removed. Rotate the pinion while tightening the nut to seat the bearings.

  8. Measure the rotating torque of the pinion. Compare this measurement with the rotating torque recorded during removal.

    Tighten 

    Tighten the nut in small increments, as needed, until the rotating torque is 0.40-0.57 N.m (3-5 lb in) greater than the rotating torque recorded during removal.

  9. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings have seated. Check the rotating torque and adjust if necessary.
  10. Install the propeller shaft. Refer to PROPELLER SHAFT REPLACEMENT - ONE PIECE or PROPELLER SHAFT REPLACEMENT - TWO PIECE in Propeller Shaft.
  11. Install the brake drums (if equipped).
  12. Install the brake rotors (if equipped). Refer to BRAKE ROTOR -- REAR in Disc Brakes.

  14. Install the tire and wheel assemblies. Refer to TIRE AND WHEEL REMOVAL AND INSTALLATION in Tires and Wheels.
  15. Inspect and add axle lubricant to the axle housing, if necessary. Refer to Lubricant Level Check (7.6 Axle)  or Lubricant Level Check (8.6 Axle) .
