2. Install the new left-hand ring gear bolts.
Hand start each bolt in ensure the ring gear is properly installed to the differential case.
Notice: Refer to Fastener Notice (See: Service Precautions/Vehicle Damage Warnings/Fastener Notice) .
3. Tighten the ring gear bolts alternately and in stages, gradually pulling the ring gear onto the differential case.
Tighten the ring gear bolts in sequence to 140 N.m (103 lb ft).
4. Install the pinion bearing cups. Refer to Drive Pinion Bearings Replacement (See: Pinion Bearing/Service and Repair) .
5. Determine the selective shim thickness for the pinion gear. Refer to Pinion Depth Adjustment (See: Service and Repair/Removal and
Replacement/Rear Drive Axle/Pinion Depth Adjustment) .
6. Install the selective shim onto the drive pinion.
7. Install the inner pinion bearing to the pinion. Refer to Drive Pinion Bearings Replacement (See: Pinion Bearing/Service and Repair) .
8. Install a new collapsible spacer.
9. Lubricate the pinion bearings with axle lubricant. Use the proper fluid. Refer to Fluid and Lubricant Recommendations (See: Maintenance) .
10. Install the drive pinion into the axle housing.
11. Install the outer pinion bearing onto the drive pinion.
12. Install a new pinion oil seal using the J 22388 .
13. Apply sealant, GM P/N 12346004 (Canadian P/N 10953480) or equivalent, to the splines of the pinion yoke.
14. Install the pinion yoke.
Notice: Do not hammer the pinion flange/yoke onto the pinion shaft. Pinion components may be damaged if the pinion flange/yoke is hammered
onto the pinion shaft.
15. Seat the pinion yoke onto the pinion shaft by tapping it with a soft-faced hammer until a few pinion shaft threads show through the yoke.
16. Install the washer and a new pinion nut.
17. Install the J 8614-01 onto the pinion yoke.
Important: If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.
18. Tighten the pinion nut while holding the J 8614-01 .
Tighten the nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings.
