Pinion Seal - Installation






INSTALLATION

Special Tools:










1. Apply light coating of gear lubricant to the outer diameter of the flange on the sealing surface.
2. Using Driver Handle (1) and Installer (2), install pinion seal until tool bottoms on carrier.





3. Install pinion flange into position. Align index marks between pinion flange and pinion stem to maintain assembly balance and so that bearing preload is not exceeded.
4. Using Installer , lightly tap on pinion flange until adequate pinion shaft threads are exposed.





5. Clean any thread locker from pinion flange nut and the pinion shaft and apply Mopar(R) Lock & Seal Adhesive to the nut.
6. Install pinion flange nut. Apply axle grease to pinion nut washer face prior to assembly. Using Flange Wrench (1) and 32mm socket tighten pinion flange nut in small increments until the pinion nut index mark aligns with the index marking on the pinion stem.






NOTE: If pinion nut index mark exceeds the pinion stem index mark the unit must be discarded. If the pinion nut index mark falls short of the pinion stem index mark the unit will possibly generate a Noise, Vibration, or Harshness (NVH) concern.







NOTE: Torque reading must be taken with a constant rotational speed. Do not measure break away torque.

7. Using a torque wrench, measure and record the pinion rotational torque.
8. After torque reading has been obtained, compare reading to the recorded reading when removing the pinion flange. Difference in reading should be within 0 ± 0.2 N.m (0 ± 1.7 in. lbs.). Value after repair should be higher due to tighter fit of new seal.
9. Install axle assembly. Installation.
