Remove the thrust block (9) from the inside of the carrier (15) housing. Remove oil fill plug (16).

Disassemble Differential Case and Gear Assembly.

If original identification (matching) marks are not clear, mark the differential case halves (4 and 10) with a

(2)

Remove the capscrews (2 and 24) and washers (3) and separate the case halves (4 and 10).

(3)

Remove the spider (7), pinions (23), side gears (6), and thrust washers (5 and 22).

If the ring gear (8) is to be replaced for any reason, remove the rivets (11) and separate ring gear from the

case (10).

(a) Carefully center-punch rivets (11) in the center of the head on the gear side of the assembly.

(b) Use a drill l/32-inch smaller than the body of the rivet (11) to drill through the head.

(5)

If necessary to replace the differential bearings (1), remove with a suitable puller.

Remove Pinion and Cage Assembly.

(1)

Hold the yoke (29) with a suitable tool and remove the pinion shaft nut (30) and washer (31).

CAUTION

Driving the yoke will cause run-out.

Remove the pinion cage capscrews (37) and washers (38), then remove the pinion cage (26) from the car-

rier (15).

(4)

Wire the shim pack (12) together to facilitate adjustment at reassembly.

Disassemble Pinion and Cage Assembly.

Tap the pinion shaft (25) out of the cage (26) with a soft mallet or press the shaft from the cage.

(2)

Remove the oil seal (33) and retainer (34) from the cage (26).

(3)

Remove the washers (35) and outer bearing (27) from the cage (26).

(4)

Remove the spacer (36) or spacer combination from the pinion shaft (25).
