      *A for Front
      *B for Rear

      Press down on the vehicle several times to stabilize the suspension, and measure the vehicle height.

      If the camber and caster are not as specified, adjust them.

      If the steering axis inclination is not as specified after the camber and caster have been correctly adjusted, check the steering knuckle and front wheel for distortion or looseness.

  4. ADJUST CAMBER AND CASTER

    Note

    After the camber has been adjusted, inspect the toe-in.


    1. Loosen the camber adjusting cam nut and camber adjusting cam bolt.

    2. Turn the No. 1 camber adjusting cam and No. 2 camber adjusting cam in both directions, and adjust the camber and caster to the center value.

    3. The camber and caster should be as close as possible to the center value.

      *3 No. 2 Camber Adjusting Cam (LH) *4 No. 2 Camber Adjusting Cam (RH)
      *a Front of the Vehicle - -

      Tech Tips


      • Moving the No. 1 camber adjusting cam to (+) side by one notch changes the caster by approximately +0°07' and the camber by approximately +0°03'.

      • Moving the No. 2 camber adjusting cam to (+) side by one notch changes the caster by approximately +0°06' and the camber by approximately +0°04'.

      • Perform adjustments so that the value is as close as possible to the median of the specified range.

    4. Tighten the camber adjusting cam nut and camber adjusting cam bolt.
