Differential Assembly: Assembly

  1. Install new 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 side gears and side gear thrust washers into differential case.

  5. Measure side gear end play following the procedure below, and select the appropriate side gear thrust washers.
    1. Place differential case straight up so that side gear to be measured comes upward.

    2. Using thickness gauges, measure the clearance between side gear back and differential case at 3 different positions, while rotating side gear. Average the 3 readings, and then decide the clearance. (Measure the clearance of the other side as well.)

      Standard 

      Side gear back clearance : Refer to  "DIFFERENTIAL SIDE GEAR CLEARANCE ".

      CAUTION: To prevent side gear from tilting, insert thickness gauges with the same thickness from both sides.

    3. If the back clearance is outside the specification, use a thicker/thinner side gear thrust washer to adjust.

      When the back clearance is large: 

      Use a thicker thrust washer. 

      When the back clearance is small: 

      Use a thinner thrust washer. 

      CAUTION: Select a side gear thrust washer for right and left individually.
  6. Drive a lock pin into pinion mate shaft, using the pin punch.
    CAUTION: Never reuse lock pin.

  7. Press side bearing inner races to differential case, using the drift [SST: KV40105020 (-)].
    CAUTION: Never reuse side bearing inner races.

  8. Apply locking sealant into the thread hole of drive gear. Use Genuine Medium Strength Thread Locking Sealant or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".
    CAUTION: The drive gear back and threaded holes shall be cleaned and decreased sufficiently.

  9. Install drive gear to the differential case, and then tighten to the specified torque.
  10. Apply gear oil to side bearings, and install new side bearing adjusting shims (2 pieces for one side) with the same thickness as the ones installed prior to disassembly or re-install the old ones, with side bearing outer race to differential case.

    If side bearing adjusting shims have been already selected, use them.

    CAUTION: Never reuse side bearing outer race.

  11. Set the drifts [SST: KV40100610 (J-26089)] to the right and left side bearing adjusting shims individually. Compress differential case assembly and side bearing to install gear carrier assembly to differential case assembly.
    CAUTION:
    • The drift shall be placed on the center of the adjusting shims.
    • The pressure shall be as low as possible to install differential assembly into gear carrier assembly. The maximum pressure shall be 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).
    • If the adjusting shims are installed by tapping, the gear carrier may be damaged. Avoid tapping.

  12. Install dummy cover set, check and adjust drive gear runout, tooth contact, backlash, and total preload torque. Refer to "ADJUSTMENT ".
  13. Remove dummy cover set.
  14. Apply liquid gasket to mating surface of rear cover. Overlap both ends of the bead for at least 3 mm (0.12 in).

    Use Genuine Silicone RTV or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

    CAUTION: Remove old gasket adhering to the mounting surfaces. Also remove any moisture, oil, or foreign material adhering to the mounting surfaces.

  15. Set the drifts [SST: KV40100610 (J-26089)] to the right and left side bearing adjusting shims individually. Compress differential case assembly and side bearing to install rear cover.
    CAUTION:
    • The drift shall be placed on the center of the adjusting shims.
    • The pressure shall be as low as possible to install the rear cover. The maximum pressure shall be 10 kN (1 ton, 1.0 Imp ton).
    • If rear cover is forced in by tapping, rear cover may be damaged by adjusting shims. Avoid tapping.

  16. Tighten rear cover mounting bolts to the specified torque.
  17. Using the drift [SST: KV38100200 (J-26233)], drive side oil seals until it becomes flush with the carrier end.
    CAUTION:
    • Never reuse oil seals.
    • When installing, do not incline oil seals.
    • Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of oil seal.
