Sierra Classic 2500 4WD V8-6.0L (2007)
Important:
If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed.
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.
8. 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 Nm (3 - 5 inch lbs.) greater than the rotating torque
recorded during removal.
9. 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.
10. Install the propeller shaft (3) to the pinion yoke (4). Align the reference marks made during removal.
11. Install the propeller shaft yoke retaining clamps and the bolts.
Tighten the bolts to 25 Nm (18 ft. lbs.).
12. Install the rear brake drum. Refer to Brake Drum Replacement.
13. Install the wheels and tires.
14. Inspect and add axle lubricant to the axle housing, if necessary. Refer to Rear Axle Lubricant Level Inspection.
