Illustration 1 g00335318
Lower the temperature of bearing cup (11). Install bearing cup (11) in the pinion housing, as shown.Note: Reset the bearing cup with a suitable driver after the mating parts have reached a uniform temperature.
Install O-ring (12) on the pinion housing.
Illustration 2 g00335319
Lower the temperature of bearing cup (10). Install bearing cup (10) in the pinion housing, as shown.
Illustration 3 g00335320
Raise the temperature of bearing cone (9). Install bearing cone (9) on pinion shaft (4).Note: Reset the bearing cone with a suitable driver after the mating parts have reached a uniform temperature.
Illustration 4 g00335321
Use Tooling (B) and a suitable lifting device to position the pinion housing over the pinion shaft.
Use SAE 30 gear oil to lubricate the bearing.
Illustration 5 g00335322
Raise the temperature of bearing cone (8). Install bearing cone (8) on pinion shaft (4).Note: Do not reset the bearing cone at this time.
Use SAE 30 gear oil to lubricate the bearing.
Illustration 6 g00334767
Install washer (7) on the pinion shaft.
Illustration 7 g00335323
Illustration 8 g00334765
Install nut (6) on the pinion shaft. Use Tooling (A) to tighten nut (6) to load the bearings.
Illustration 9 g00335324
Install the yoke on the pinion shaft.
Use Tooling (C) to slowly turn the pinion shaft. Check the rolling torque.The rolling torque for the pinion shaft is 0.9 1.8 N m (8 16 lb in) for new bearings. If the existing bearings are used, limit the rolling torque to half of the specification.Note: If the rolling torque exceeds the specification, back off the shaft by a 1/8 turn. Reseat the bearings and repeat Steps 11 and 12.

Completed Stake
(E) The spherical radius of the tool for peening must be 7.5 to 8.0 mm (0.295 to 0.315 inch).
(F) The acceptable angle of the tool for peening is 20 10 degrees.
(G) The minimum length of the crimp is 4.7 mm (0.185 inch).
(H) The minimum depth of the crimp is 2.5 mm (0.098 inch).
(J) Top viewNote: Before you stake the nut, make sure that the pinion shaft has zero end play.
When the rolling torque is correct, stake nut (6) by peening the collar in slot (5) in the pinion shaft. See Illustration 11 and the caption for the correct dimensions.

Illustration 13 g00334761
Use Tooling (D) to install lip seal (3) in retainer (2). Make sure that the sealing lip is facing inward.
Illustration 14 g00334760
Put retainer (2) in position on the pinion housing. Install the washers and bolts (1).
Use SAE 30 gear oil to lubricate lip seal (3).End By:
Install the differential and the bevel gear. Refer to Disassembly and Assembly, "Differential and Bevel Gear - Install".
