Installation Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 GMC Savana Special, 2003 GMC Savana Camper Special, 2003 GMC Savana, 2003 Chevrolet RV Cutaway, and 2003 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the 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.
  2. Apply sealant GM P/N 12346004 (Canadian P/N 10953480) or equivalent to the splines of the drive pinion yoke.

  3. Install the pinion yoke.

    Align the reference marks made during removal.

    CAUTION: 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 onto the pinion shaft by tapping it with a soft-faced hammer until a few pinion shaft threads show through the flange.
  5. Install the washer.
  6. Install a new pinion nut.

  7. Install the J-8614-01  onto the pinion flange as shown.
    CAUTION: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    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 

    Tighten the pinion nut until the pinon 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. Compare the measurement with the rotating torque recorded earlier.

    Tighten 

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

  10. 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.
  11. Install the propeller shaft to the pinion yoke. Align the reference marks made during removal.
  12. Install the pinion yoke retainers and the bolts.

    Tighten 

    Tighten the pinion yoke retainer bolts to 25 N.m (18 lb ft).

  13. Inspect the axle lubricant level, and add, if necessary. Refer to Lubricant Level Inspection - Front Drive Axle .
  14. Install the brake calipers. Refer to BRAKE CALIPERS .
  15. Install the tire and wheel assemblies. Refer to TIRE AND WHEEL REMOVAL AND INSTALLATION .
  16. Lower the vehicle.
