PINION FLANGE SEAL

REMOVAL
1. Raise and support the vehicle.
2. Drain the differential housing.
3. Remove the muffler.
4. Disconnect the propeller shaft from the rear pinion flange and position out of way.
5. Disconnect the halfshafts at the differential connecting flanges and position them aside.





6. Use the torque meter (1) to measure resistance to rotation at the pinion flange. Record the amount of friction torque.





7. Using the Special Tool C-3281 Flange Wrench (2) to hold the pinion flange (1).
8. Remove and discard the collared nut.
9. Remove the pinion flange (1).





10. Remove the pinion flange seal (1) with a suitable prying tool.

INSTALLATION
1. Remove any burrs or nicks from the seal bore.





2. Drive in a new pinion flange seal (1) using Special Tool 9231 Drift and a mallet.
3. Install the pinion flange.





4. Install a new pinion shaft collared nut. Hold the pinion flange (1) with Special Tool C-3281 Flange Wrench (2). Tighten the nut to 180 Nm (133 ft. lbs.).
5. Check the resistance to rotation torque. If the resistance is less than the previously recorded value, tighten the pinion in 5 Nm (44 inch lbs.) increments until the resistance amount is reached.
6. Connect the halfshafts to the differential connecting flanges.
7. Install the propeller shaft.
8. Install the muffler.
9. Fill the differential housing to specification.
10. Lower the vehicle.
