  2. INSPECT TIRES 

    Refer to PROCEDURE - Step 1

  3. MEASURE VEHICLE HEIGHT 
    NOTE:
    • Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
    • Be sure to perform measurement on a level surface.
    • If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.
    • Inspect while the vehicle is unloaded.
    • 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.
    1. Bounce the vehicle up and down at the corners to stabilize the suspension.
    2. Measure the vehicle height.

      1. If the measured value is not within the specification, calculate the required adjustment amount using the formula below.
        GTY765160Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

        Camber adjustment amount = center of the specified range - measured value

        Check the combination of the installed bolts. Select appropriate bolts from the tables below to adjust the camber to the specified values.

        HINT: 

        Try to adjust the camber to the center of the specified values.

        To move the axle hub toward (+) in step B To move the axle hub toward (-) in step B
        Refer to table (1) (To move the axle hub toward the positive side) in the following below Refer to table (2) (To move the axle hub toward the negative side) in the following below

        The vehicle body and suspension may be damaged if the camber cannot be correctly adjusted according to the table above.

        NOTE:

        Replace the nut with a new one when replacing the bolt.

      HINT: 

      Replace one bolt at a time when replacing both bolts.

  6. INSPECT TOE-IN 
    NOTE:

    Inspect while the vehicle is unloaded.
