FRONT WHEEL ALIGNMENT ADJUSTMENT

CAUTION / NOTICE / HINT

Note

For vehicles equipped with VSC, if wheel alignment has been adjusted, and if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:


  1. Check that the steering wheel is in the centered position.

  2. Disconnect the negative battery terminal for more than 2 seconds.

  3. Reconnect the negative battery terminal.

  4. Perform zero point calibration of the yaw rate and deceleration sensor and test mode inspection Click here.

PROCEDURE


  1. INSPECT TIRE


    1. Inspect the tires Click here.

  2. INSPECT VEHICLE HEIGHT

    Note

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

      If the vehicle height is not as specified, adjust the height by pressing down on the vehicle several times to stabilize the suspension.

      Note

      The standard value shown here is a value that is used for adjusting the wheel alignment and does not indicate the height of an actual vehicle.

  3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

    *1 Gauge
    *2 Alignment Tester

    1. Install the camber-caster-kingpin gauge or place the front wheels on the center of the wheel alignment tester.

    2. Inspect the camber, caster and steering axis inclination.

  4. ADJUST CAMBER AND CASTER

    Tech Tips

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


    1. Loosen the front adjusting cam bolt and rear adjusting cam nut.

    2. Turn the front adjusting cam and rear adjusting cam in both directions, and adjust the camber and caster to the center value.

      B001AF0E10

      Tech Tips


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

      • Make sure the difference between the left and right camber and caster is within +/-30' (0.5°).

    3. B0018BTE05

      Read the adjustment chart (example).


      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°00' (4.00°)

      3. Mark the alignment value measured when the vehicle is unloaded on the adjustment chart.

        Measured Value (Reference)
        Camber Caster
        0°11' (0.18°) 4°38' (4.63°)

      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.
