    2. for rear differential:


      1. Stop the vehicle on a level surface.

      2. Remove the differential filler plug and gasket.

      3. Remove the drain plug and gasket, and drain the oil.

      4. Install a new gasket and the drain plug.

        Torque:

  2. ADD DIFFERENTIAL OIL

      *a 0 to 5 mm (0 to 0.196 in.)

      Add differential oil so that the oil level is within 5 mm (0 to 0.196 in.) from the bottom lip of the differential filler plug hole.

      Note


      • After changing the oil seal, drive the vehicle and then check the oil level again.

      • Too much or too little oil will lead to differential problems.

      Tech Tips

      If necessary, fill the differential carrier assembly with hypoid gear oil.

    2. Check for oil leakage when the oil level is low.

    3. for front differential:

        *1 10 mm Straight Hexagon Wrench
        *2 10 mm Union Nut Wrench
        *3 Socket Adaptor

        Using SST and the 10 mm straight hexagon wrench, 10 mm union nut wrench and socket adaptor, install a new gasket and the differential filler plug.

        SST

        Torque:
        39 N*m  { 400 kgf*cm, 29 ft.*lbf }

        Note


        • Make sure all the tools are connected in a straight line.

        • Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench.

          Formula
          T' = T x L3 / (L1 + L2 + L3)
          - T' = Spec. value of torque wrench
          - T = Value of specified tightening torque
          - L1 = Length of union nut wrench
          - L2 = Length of SST
          - L3 = Length of torque wrench

    4. for rear differential:


      1. Install a new gasket and the differential filler plug.

        Torque:
        49 N*m  { 500 kgf*cm, 36 ft.*lbf }
