Removal & Installation
- Before servicing the vehicle, refer to the Precautions section.
Remove rear axle assembly from vehicle.
Measure axle assembly rotating torque and record measurement for reuse on assembly.
Using flange holder C-3281(1) and 41mm socket, remove pinion flange nut and discard.
NOTEDue to axle imbalance concerns, it is necessary to make sure pinion flange-to-shaft orientation is maintained. If alignment marks are not visible, apply appropriate marks before removing pinion flange.
- Using puller 1026 (1), remove pinion flange (2) from pinion shaft.
- Using suitable tool, remove pinion seal and discard.
- Apply light coating of gear lubricant to the lip of the pinion seal.
- Using a seal driver, install pinion seal until tool bottoms on carrier.
- Install pinion flange into position. Align index marks to maintain assembly balance.
- Lightly tap on pinion flange until adequate pinion shaft threads are exposed.
- Install new pinion flange nut. Using flange holder tool C-3281and 41mm socket, torque nut to 100 ft. lbs. (136 Nm).
- Measure assembly turning torque. Axle assembly rotating torque must be should be equal to the reading recorded upon seal/flange removal.
- If rotating torque is low, increase pinion flange nut torque in 60 inch lbs. (7 Nm) increments. Repeat until proper rotating torque is received.
Stake pinion flange nut (1) as shown.
- Install rear axle assembly.
