Differential Gear Inspection

1. Measure the differential side gear O.D. and the dif-

ferential case I.D. to determine the side gear to case

clearance(Fig.39).Replacecomponents asnecessary.

SIDE GEAR TO CASE CLEARANCE:

0.002 to 0.012 in. (0.05 to 0.30 mm)

SIDE GEAR O.D. (Factory Spec.):

1.335 to 1.337 in. (33.91 to 33.95 mm)

DIFFERENTIAL CASE I.D. ( Factory Spec.):

1.339 to 1.341 in. (34.00 to 34.06 mm)

2. Measure the differential pinion shaft O.D. and the

pinion gear I.D. to determine the pinion shaft to pinion

gear clearance (Fig. 40). Replace components as nec-

essary.

PINION SHAFT TO PINION GEAR CLEARANCE:

0.001 to 0.010 in. (0.03 to 0.25 mm)

PINION SHAFT O.D. (Factory Spec.):

0.550 to 0.551 in. (13.97 to 13.10 mm)

PINION GEAR I.D. (Factory Spec.):

0.551 to 0.552 in. (13.10 to 14.02 mm)

3. Inspectall gears,shafts, bearings, cases andcovers

for damage and wear. Replace components as neces-

sary.
