Front Wheel Alignment -- Adjustment



1. INSPECT TIRE

  1. Inspect the tires (Toyota Fortuner RM0000010MW00GX.html).



2. INSPECT VEHICLE HEIGHT

NOTICE:
Before inspecting the wheel alignment, adjust the vehicle height to the specification.

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

  1. If the toe-in is not as specified, adjust it at the rack ends.


4. ADJUST TOE-IN

  1. Detach the rack boot set clips.

  1. Loosen the tie rod end lock nuts.

  1. Turn the right and left rack ends by an equal amount to adjust the toe-in to the center value.

    1. If the camber and caster are not as specified, adjust them.
    1. 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.


7. ADJUST CAMBER AND CASTER
NOTICE:
After the camber has been adjusted, inspect the toe-in.

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



  1. 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.

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

  1. How to read the adjustment chart (using examples).

    1. Find the wheel alignment standard value applicable for the particular model.

    2. Mark the selected standard value on the adjustment chart.

      Standard value (reference):
      Camber
      		Caster
      0°00' (0.00°)
      		4°20' (4.30°)

      		Caster
      0°10' (0.00°)
      		3°50' (3.83°)


    4. As shown in the chart, read the distance from the marked point to 0, and adjust the front and/or rear adjusting cams accordingly.

      Amount to turn adjusting cams (by gradation):
      No. 1 camber adjusting cam
      		No. 2 camber adjusting cam
      +3.0 mm
