DIFFERENTIAL SYSTEM GENERAL


  1. OUTLINE


    1. Front Differential (AWD Models)


      1. SD18B type front differential is used.

    2. Rear Differential


      1. FD21C type rear differential is used on the models with 2GR-FSE engine.

      2. FD20A type rear differential is used on the models with 4GR-FSE engine.

      3. A pre-torque mechanism is used to improve the initial acceleration performance of the vehicle on slippery road surfaces.

      4. A lightweight carrier with optimized thickness and a streamlined rib is used on the FD21C type rear differential.

      5. Low viscosity oil is used, thus improving fuel consumption.
