DIFFERENTIAL OIL REPLACEMENT

PROCEDURE


  1. DRAIN DIFFERENTIAL OIL


    1. for front differential:


      1. Stop the vehicle on a level surface.

      2. B003MC0C04
        *1 10 mm Straight Hexagon Wrench
        *2 10 mm Union Nut Wrench
        *3 Socket Adaptor

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

        SST
        09961-00950

      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.

      Recommended Viscosity
      Front Differential
      SAE 75W-85
      Rear Differential
      SAE 75W-85
      Differential Oil Type
      Front Differential
      Toyota Genuine Differential gear oil LT 75W-85 GL-5 or equivalent
      Rear Differential
      Toyota Genuine Differential gear oil LT 75W-85 GL-5 or equivalent
      Standard Front Differential Oil Capacity
      1.55 to 1.65 liters (1.64 to 1.74 US qts., 1.37 to 1.45 Imp. qts.)
      Standard Rear Differential Oil Capacity
      3.55 to 3.65 liters (3.76 to 3.85 US qts., 3.13 to 3.21 Imp. qts.)

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

    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 }
