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

      4. Install a new gasket and the drain plug.

        Torque:
        64.7 N*m  { 660 kgf*cm, 48 ft.*lbf }

    2. for rear differential:


      1. Stop the vehicle on a level surface.

      2. Remove the rear axle housing filler plug and gasket.

      3. Remove the rear axle housing drain plug and gasket, and drain the oil.

      4. Install a new gasket and the rear axle housing drain plug.

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

  2. ADD DIFFERENTIAL OIL


    1. B003P75C22
      *a 0 to 5 mm

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

      Note


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

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

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

    3. B003S1KC03
      *1 10 mm Straight Hexagon Wrench
      *2 10 mm Union Nut Wrench
      *3 Socket Adaptor

      for front differential:


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

        SST
        09961-00950
        Torque:
        39.2 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 rear axle housing filler plug.

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