1. Pinion shaft
2. Measure the differential pinion shaft O.D. and the pinion gear I.D. to
determine the pinion shaft to pinion gear clearance
components as necessary.
PINION SHAFT TO PINION GEAR CLEARANCE: 0.03 to 0.25 mm (0.001
to 0.010 in)
PINION SHAFT O.D. (Factory Spec.): 13.97 to 13.10 mm (0.550 to 0.551 in)
PINION GEAR I.D. (Factory Spec.): 13.10 to 14.02 mm (0.551 to 0.552 in)
3. Inspect all gears, shafts, bearings, cases and covers for damage and wear.
Replace components as necessary.
1. If the ring gear was removed from the differential case, use medium strength
Loctite thread locker and tighten the mounting screws from 30 to 34 N·m
(22 to 25 ft-lb).
2. Apply molybdenum di-sulfide lubricant (Three Bond 1901 or equivalent)
to the splines and bearing surfaces of the differential pinion gears, pinion
washers and side gears.
3. Install the side gear shims and side gears in their original location in the
differential case.
4. Place the differential pinion gears and pinion washers in their original location
in the differential case. Temporarily install the differential pinion shaft.
