Differential Assembly

WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install side gear thrust washers with the same thickness as the ones installed prior to disassembly, or reinstall the old ones on the side gears.

  2. Install the side gears and side gear thrust washers into the differential case.
  3. Install the pinion mate thrust washers to the two pinion mate gears. Then install the pinion mate gears with the pinion mate thrust washers by aligning them in diagonally opposite positions and rotating them into the differential case.

  4. Install the pinion mate shaft and align the lock pin hole on the pinion mate shaft with the lock pin hole on the differential case.
  5. Measure the side gear end play. If necessary, select the appropriate side gear thrust washers. Refer to "SIDE GEAR BACK CLEARANCE ".

  6. Drive a new lock pin into the pinion mate shaft until it is flush with the differential case using suitable tool.
    CAUTION: Do not reuse lock pin.

  8. Install and tighten the new drive gear bolts to the specified torque. Refer to "COMPONENTS ".
    CAUTION:
    • Make sure the drive gear back and threaded holes are clean.
    • Do not reuse drive gear bolts.
    • Tighten new drive gear bolts in a crisscross pattern.

  9. Press the new side bearing inner races to the differential case using Tools.

    Tool number A: KV38100300 (J-25523) 

    B: ST33081000 

    CAUTION: Do not reuse side bearing inner races.

  10. Install side bearing adjusters into gear carrier.
  11. Apply differential gear oil to the side bearings, and install the differential case assembly with the side bearing outer races into the gear carrier.
    CAUTION: Do not reuse side bearing outer race when replacing side bearing inner race (replace as a set).

    G04756706
  12. Install the side bearing caps with the matching marks aligned.
    NOTE: Do not tighten at this step. This allows further tightening of side bearing adjusters.

  14. Check and adjust tooth contact, backlash, drive gear runout and total preload torque. Refer to "TOOTH CONTACT ", "BACKLASH ", "DRIVE GEAR RUNOUT " and "TOTAL PRELOAD TORQUE ".

    Recheck above items.

    • After adjusting tooth contact and backlash secure side bearing adjuster with screws and tighten side bearing cap bolt to the specified torque. Refer to "COMPONENTS ".

  15. Apply multi-purpose grease to the lips of the new side oil seal. Then drive the new side oil seal in evenly to the gear carrier using suitable tool.
    CAUTION:
    • Do not reuse side oil seal.
    • Do not incline the new side oil seal when installing.
    • Apply multi-purpose grease to the lips of the new side oil seal.
  16. Install the extension tube with a new O-ring.
    CAUTION:
    • Do not reuse O-ring.
    • If the extension tube is being replaced, install a new axle shaft bearing.

  17. Apply 3 mm (0.12 in) bead of sealant to the mating surface of the carrier cover as shown.
    CAUTION: Remove any old sealant adhering to the mating surfaces. Also remove any moisture, oil, or foreign material adhering to the application and mating surfaces.
  18. Install the carrier cover to the gear carrier. Tighten the bolts to the specified torque. Refer to "COMPONENTS ".
  19. Install side shaft and side flange.
