  7. Using flange holder C-3281(1) 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.

  9. Using puller 1026 (1), remove pinion flange (2) from pinion shaft.
  10.  
  11. Using suitable tool, remove pinion seal and discard.
  12.  

To install:

  1. Apply light coating of gear lubricant to the lip of the pinion seal.
  2.  
  3. Using a seal driver, install pinion seal until tool bottoms on carrier.
  4.  
  5. Install pinion flange into position. Align index marks to maintain assembly balance.
  6.  
  7. Lightly tap on pinion flange until adequate pinion shaft threads are exposed.
  8.  
  9. Install new pinion flange nut. Using flange holder tool C-3281and 41mm socket, torque nut to 100 ft. lbs. (136 Nm).
  10.  
  11. Measure assembly turning torque. Axle assembly rotating torque must be should be equal to the reading recorded upon seal/flange removal.
  12.  
  13. If rotating torque is low, increase pinion flange nut torque in 60 inch lbs. (7 Nm) increments. Repeat until proper rotating torque is received.
  14.  
  15. Stake pinion flange nut (1) as shown.
