FRONT WHEEL ALIGNMENT ADJUSTMENT

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.


  1. INSPECT TIRES

  2. MEASURE VEHICLE HEIGHT

    A01J98LE01

    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.


    1. Bounce the vehicle up and down at the corners to stabilize the suspension.

    2. Measure the vehicle height.


        Measurement points:

      • A: Ground clearance of front No. 1 lower suspension arm bushing set bolt center


      • B: Ground clearance of rear axle beam bushing set bolt center


      • C: Ground clearance of front wheel center


      • D: Ground clearance of rear wheel center

  4. ADJUST CAMBER

    Note

    Inspect toe-in after the camber has been adjusted.


    1. Remove the front wheel.

    2. A01JAZQ

      Loosen the 2 nuts.

      Note

      Keep the bolts inserted.

    3. Clean the installation surfaces of the front shock absorber and the steering knuckle.

    4. Temporarily install the 2 nuts. (Step A)

    5. A01J8XJ

      Fully push or pull the front axle hub in the direction of the required adjustment. (Step B)

    6. A01JAZQ

      Tighten the nuts.

      Torque:
      240 N*m  { 2447 kgf*cm, 177 ft.*lbf }

      Note

      Keep the bolts from rotating when tightening the nuts.

    7. Install the front wheel.

      Torque:
      103 N*m  { 1050 kgf*cm, 76 ft.*lbf }
    8. A01JB6RE01

      Check the camber.

      If the measured value is not within the specification, calculate the required adjustment amount using the formula below.

      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.

      Tech Tips

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

      Move the axle hub toward (+) in step B Move the axle hub toward (-) in step B
      Refer to table (1) (Move the axle hub toward the positive side) Refer to table (2) (Move the axle hub toward the negative side)

      A01JAA5E56

      Note

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

      The body and suspension may be damaged if the camber is not correctly adjusted according to the tables above.

    9. Repeat the steps mentioned above. In Step A, replace 1 or 2 selected bolts.

      Tech Tips

      Replace one bolt at a time when replacing both bolts.

  5. INSPECT TOE-IN

    Note

    Inspect while the vehicle is unloaded.


    1. Bounce the vehicle up and down at the corners to stabilize the suspension.

    2. Release the parking brake and move the shift lever to N.

    3. Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)

      *1 Tread Center Mark
      *2 Dimension B

      Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

    5. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180° using the front tire valve as a reference point.

      Tech Tips

      Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from Step C again.

      Loosen the tie rod end lock nuts.

    4. Adjust the rack ends if the difference in thread length between the right and left rack ends is not within the specified range.


      1. Extend the shorter rack end if the measured toe-in deviates toward the outer-side.

      2. Shorten the longer rack end if the measured toe-in deviates toward the inner-side.

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

    6. Make sure that the thread lengths of the right and left rack ends are the same.

    7. Tighten the tie rod end lock nuts.
