(3) Torque for ten bolts that fasten carrier (4) to the axle housing ... 270 25 N m (200 18 lb ft)(6) Torque for eight bolts that fasten pinion housing (7) to carrier (4) ... 135 15 N m (100 11 lb ft)(13) Apply 9S3263 Thread Lock to the internal threads in bevel gear (12). Torque 24 bolts that fasten bevel gear (12) to the differential group ... 135 15 N m (100 11 lb ft)(16) Torque for four bolts that fasten the caps to carrier (4) after the preload and backlash adjustments have been made ... 270 25 N m (200 18 lb ft)Adjustment Procedure:
Pinion Preload Adjustment
1. Install bearing cups in housing (7). Bearing cups must be seated against the shoulders in housing (7).2. Install the bearing cone next to the pinion teeth on pinion (8). Bearing cone must be seated against the shoulder on pinion (8).3. Lubricate bearing and install pinion (8) in housing (7). Lubricate and install bearing cone, washer (9) and nut (10).4. Position the assembly in a soft jawed vise. Tighten the vise against the teeth on pinion (8). While turning housing (7) tighten nut (10) until the torque needed to turn the pinion is: New bearings ... 0.7 to 1.1 N m (6 to 10 lb in)Used bearings ... 0.35 to 0.55 N m (3 to 5 lb in)Check to be sure pinion shaft (8) has zero end play. 5. When the torque needed to turn the pinion is correct, stake nut (10) by peening the collar on the nut into the key slot in pinion shaft (8). See illustration A for the correct tooling and dimensions. The nut may be reused if the collar is not cracked during removal or staking.Differential Backlash And Bearing Adjustment
The following procedure controls backlash and bearing preload. This procedure gives the same results for used and new bearings.1. Fasten pinion housing (7) to carrier (4). If original gears, carrier assembly and housing are used again, use the original thickness of shims (5). If any of these parts are replaced, install a shim pack thickness of 80% of a new full shim pack. Shim pack (5) thickness may have to be changed when adjusting the tooth contact pattern.2. Torque for eight bolts (6) ... 135 15 N m (100 11 lb ft)3. With housing (7) fastened to carrier (4), position pinion (8) in the vertical position, downward.4. Lubricate bearings and install bearing cups on the differential bearings to protect them.5. Install differential in carrier (4) with bevel gear (12) on side opposite the pin hole in carrier (4).6. Install caps (1) and (14) and adjustment rings (2) and (15). Adjustment rings (2) and (15) must turn freely.7. Tighten one bolt (16) on caps (1) and (14) to a torque of 70 N m (50 lb ft) and the other bolt on caps (1) and (14) to a torque of 70 N m (50
