  6. Insert Tool into differential side gear from transaxle case side.
  7. Move Tool up and down and measure dial indicator deflection.
  8. Select proper thickness of differential side bearing adjusting shim(s).

    Suitable shim thickness = Dial indicator deflection + Specified bearing preload 

    Differential side bearing preload adjusting shim: Refer to " DIFFERENTIAL SIDE BEARING PRELOAD ADJUSTING SHIMS  "  .

    Bearing preload: 0.05 - 0.09 mm (0.0020 - 0.0035 in) 

  9. Remove converter housing from transaxle case.
  10. Remove final drive assembly from transaxle case.

    • Turn final drive assembly in both directions several times to seat bearing rollers correctly. 

      Turning torque of final drive assembly (New bearing): 0.8 - 1.5 N-m (8.0 - 15.7 kg-cm, 7 - 13 in-lb) 

    • When old bearing is used again, turning torque will be slightly less than the above. 
    • Make sure torque is close to the specified range. 

      Preload adapter: - (J39713)
