9 3/4 Inch Ring Gear

1. Remove differential bearing cups and tag for assembly reference.
2. Secure differential in a suitable vise and drive out pinion shaft lockpin.
3. Remove differential bearing cone and roller using a suitable puller and plug tool No. J-8107-3 or equivalent. Tag cone and rollers for assembly reference.
4. Remove spacer, pinion shaft, pinions, side gears and thrust washers from differential case.
5. Remove ring gear attaching bolts and the ring gear.
6. Position differential side gears and new thrust washers in differential case.
7. Position differential pinions and new thrust washers in differential case.
8. Install pinion shaft in case, then align hole in shaft with hole in case and drive lockpin into position. Peen hole to prevent pin from falling from case.
9. Install ring gear and torque bolts alternately and evenly to 110 ft. lbs.
10. Position side bearings onto case and seat bearings using a suitable driver.
11. Determine total amount of shims needed to set backlash as follows:
a. Place differential case in carrier and install bearing caps in original position. Tighten caps just enough to retain in place.
b. Install dial indicator on carrier with indicator button contacting back surface of ring gear.
c. Rotate differential case and note runout. If runout exceeds 0.002 inch, remove differential case and the ring gear from case.
d. Reinstall case and check runout at case flange. If runout exceeds 0.002 inch, the bearing or differential case is defective and corrections should be made before proceeding.
e. Position two screwdrivers between bearing cup and ring gear on opposite side of ring gear. Apply force to screwdrivers to move differential case as far as possible toward dial indicator. Rock the ring gear to seat bearings and, with force still applied, set dial indicator to "0".
f. Reposition screwdrivers between bearing cup and carrier on ring gear side. Apply force to screwdrivers to move differential case as far as possible toward center of carrier and note indicator readings.
g. Remove differential case from carrier.
