clearance (Fig. 42). Replace components 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 t o 1.337 in. (33.91 to 33.95 mm)
DIFFERENTIAL CASE I.D. (Factory Spec.):
1.339 t o 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. 43). 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 t o 0.551 in. (13.97 to 13.10 mm)
PINION GEAR I.D. (Factory Spec.):
0.551 t o 0.552 in. (13.10 to 14.02 mm)
