  6. Insert Tool into differential side gear from transmission 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 : Refer to preload adjusting shim  "DIFFERENTIAL SIDE BEARING PRELOAD ADJUSTING SHIMS ".

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

  9. Remove converter housing from transmission case.
  10. Remove final drive assembly from transmission case.
  11. Remove differential side bearing outer race from transmission case.

  12. Reinstall differential side bearing outer race and shim(s) selected from SDS table on transmission case.
  13. Reinstall converter housing on transmission case and tighten transmission case fixing bolts to the specified torque. Refer to "OVERHAUL ".
  14. Insert Tool and measure turning torque of final drive assembly.
    • Turn final drive assembly in both directions several times to seat bearing rollers correctly. 

      Turning torque of final drive assembly (New bearing): 0.78 - 1.37 N-m (8.0 - 14.0 kg-cm, (6.9 - 12.2 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 : RE4F04B-(J39713)
