Tahoe 4WD V8-6.0L Hybrid (2008)
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.
11. 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.
12. Install the washer and a new pinion nut.
13. Install the J 8614-01 onto the pinion yoke as shown.
Notice: Refer to Fastener Notice .
Important: If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.
14. 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.
15. Measure the rotating torque of the pinion. Compare this measurement with the rotating torque recorded during removal.
Tighten the nut in small increments, as needed, until the rotating torque is 0.40-0.57 N.m (3-5 lb in) greater than the rotating torque
recorded during removal.
16. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings have seated. Recheck the rotating torque and adjust if
necessary.
17. Determine the selective shim thickness for the pinion gear bearing retainer. Refer to Pinion Depth Adjustment (10.5 Inch Axle) (See: Service and
Repair/Removal and Replacement/Rear Drive Axle/Pinion Depth Adjustment (10.5 Inch Axle))Pinion Depth Adjustment (8.6, 9.5LD Axle) (See:
Service and Repair/Removal and Replacement/Rear Drive Axle/Pinion Depth Adjustment (8.6, 9.5LD Axle)) .
