    A: Drift bar [SST: ST30611000 (J-25742-1)]
    B: Drift [SST: ST30313000 (J-25742-3)]
    C: Drift [SST: KV38100200 (J-26233)]
    CAUTION:
    • First tap the drive pinion bearing outer race until it becomes flush with the gear carrier.
    • Never reuse drive pinion front and rear bearing outer race.
  2. Select pinion height adjusting washer. Refer to ADJUSTMENT .
  3. Install selected drive pinion height adjusting washer (2) to drive pinion. Press pinion rear bearing inner race (1) to it, using drift (A) [SST: ST30901000 (J-26010-01)].

    CAUTION:

    Never reuse collapsible spacer.

  5. Assemble drive pinion into gear carrier.
    CAUTION:

    Apply gear oil to pinion rear bearing.

  6. Assemble pinion front bearing inner race to drive pinion assembly.
    CAUTION:
    • Never reuse pinion front bearing inner race.
    • Apply gear oil to pinion front bearing.
  7. Using drift [SST: ST33200000 (J-26082)], press the pinion front bearing inner race to drive pinion as far as drive pinion nut can be tightened.

    A: Flange wrench (commercial service tool)
    B: Preload gauge [SST: ST3127S000 (J-25765-A)]
    CAUTION:
    • Apply anti-corrosion oil to the thread and seat of the drive pinion lock nut
    • Never reuse drive pinion lock nut.
  11. Tighten to drive pinion lock nut using flange wrench (commercial service tool), while adjusting pinion bearing preload torque using preload gauge [SST: ST3127S000 (J-25765-A)].
    Pinion bearing preload : Refer to PRELOAD TORQUE .
    CAUTION:
    • Adjust to the lower limit of the drive pinion lock nut tightening torque first.
    • After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rotation malfunction, and other malfunctions.
  12. Install differential case assembly. Refer to ASSEMBLY .
    CAUTION:

    Never install carrier cover yet.

  13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash. Refer to ADJUSTMENT .
  14. Install side shaft. Refer to ASSEMBLY .
  15. Check and adjust companion flange runout. Refer to ADJUSTMENT .
  16. Check total preload torque. Refer to ADJUSTMENT .
