WHEN REMOVING,INSTALLING OR REPLACING PARTS WHEEL ALIGNMENT STANDARD

Note

If the 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:


  • Perform zero point calibration of the yaw rate and acceleration sensor and the test mode inspection.


  1. MEASURE VEHICLE HEIGHT

    Note

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

      *b Rear Side

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


      • (*1) Light duty

      • (*2) Heavy duty

      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.

    2. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

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

  • Inspect the camber, caster and steering axis inclination.




  • INSPECT TOE-IN
