  8. Install new  pinion seal with Installer (special tool #8882, Installer, Pinion Seal) (2) and Handle (special tool #C-4171, Driver Handle, Universal) (1).
  9. Apply a light coat of teflon sealant to the pinion flange splines.
  10. Hold pinion and lightly tap the pinion flange onto the pinion shaft, until a few threads are showing.
  11. Install pinion flange washer and new  pinion nut.
  12. Hold pinion flange with Flange Wrench (special tool #8979, Wrench, Pinion Flange) and tighten pinion nut until end play is eliminated.

  13. Rotate pinion several times to seat pinion bearings.
  14. Measure Pinion Torque To Rotate (1) with an inch pound torque wrench (2). Tighten pinion nut in 6.8 N.m (5 ft. lbs.) increments until pinion torque to rotate is reached.

    Pinion Torque To Rotate is:

    • New Pinion Bearings:  1.7 - 2.8 N.m (15 - 25 in. lbs.)
    • Original Pinion Bearings:  1.1 - 2.2 N.m (10 - 20 in. lbs.)
  15. Rotate pinion several times then verify pinion torque to rotate again.
  16. Position ring gear on differential case and start two new  ring gear bolts.
  17. Install remaining new  ring gear bolts and tighten them alternately to seat the ring gear. Torque ring gear bolts to 140 N.m (103 ft. lbs.).
  18. Install differential in housing.
  19. Measure Total Torque to Rotate (TTTR) with an inch pound torque wrench.

    Total Torque to Rotate is:

    • New Bearings:  3.4 - 5.6 N.m (30 - 50 in. lbs.)
    • Original Bearings:  2.8 - 5.1 N.m (25 - 45 in. lbs.)
      NOTE:

      If TTTR is to high, back off adjusters evenly on both sides slightly and check TTTR again. If TTTR is to low, tighten adjusters evenly on both sides slightly and check TTTR again.

  20. Verify ring gear backlash and gear contact pattern.
