Seal - Pinion Flange

SEAL-PINION FLANGE
REMOVAL





1. Remove rear axle assembly from vehicle. Refer to Rear Axle Removal.
2. Measure axle assembly rotating torque and record measurement for reuse on assembly.





3. Using flange holder C-3281(l) and 41mm socket, remove pinion flange nut and discard.

NOTE: Due 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.





4. Using puller 1026 (1), remove pinion flange (2) from pinion shaft.





5. Using suitable tool (1), remove pinion seal (2) and discard.

INSTALLATION
1. Apply light coating of gear lubricant to the lip of the pinion seal.





2. Using Tool 9231A (1), install pinion seal until tool bottoms on carrier.





3. Install pinion flange into position. Align index marks to maintain assembly balance.
4. Using Installer 6448A (1), lightly tap on pinion flange (2) until adequate pinion shaft threads are exposed.





5. Install new pinion flange nut. Using flange holder tool C-3281 (1) and 41 mm socket, torque nut to 136 Nm (100 ft. lbs.).





6. Measure assembly turning torque. Axle assembly rotating torque must be should be equal to the reading recorded upon seal/flange removal.





7. If rotating torque is low, increase pinion flange nut torque in 7 Nm (5 ft. lbs.) increments. Repeat until proper rotating torque is received.





8. Stake pinion flange nut (1) as shown.
9. Install rear axle assembly. Refer to Rear Axle Installation.
