FRONT WHEEL ALIGNMENT ADJUSTMENT

Note

For vehicles equipped with VSC, 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:


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


  1. INSPECT TIRES

      Note


      • Perform the inspection while the vehicle is empty (with the tire puncture repair kit in the vehicle and the tools removed from the vehicle).

      • The tolerance for the difference between the left and right wheels is 30' (0.5°) or less for both the camber and caster.

    5. Remove the camber-caster-steering axis inclination gauge and attachment.

    6. Install the wheel cap.

      If the caster and steering axis inclination are not within the specified values after the camber has been correctly adjusted, recheck the suspension parts for damage and wear.

  5. ADJUST CAMBER

    Note

    Inspect the toe-in after the camber has been adjusted.

      Check the camber.

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

      (Camber adjustment amount) = Center of specified range - Measured value

      Check the combination of installed bolts. Select appropriate bolts from the table below to adjust the camber to within the specified range.

      Tech Tips

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

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

    11. Table (1) (Move the axle toward the positive side)

    12. Table (2) (Move the axle toward the negative side).

      A0117ULE08

      The body and suspension may be damaged if the camber is not correctly adjusted in accordance with the above table.

      Note

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

    13. Repeat the steps mentioned above. At step (A), replace 1 or 2 selected bolts.

      Tech Tips

      Replace one bolt at a time when replacing 2 bolts.

  6. INSPECT TOE-IN


    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 the neutral position.

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

      *a Center marks

      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 the beginning again.

    1. Measure the thread lengths of the right and left tie rod ends.

      Standard
      Difference in thread length of 1.5 mm (0.0591 in.) or less

    2. Loosen the tie rod lock nuts.

    3. Adjust the tie rods if the difference in thread length between the right and left tie rod ends is not within the specified range.


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

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

    4. Turn the right and left tie rods by an equal amount to adjust the toe-in.

      Tech Tips

      Try to adjust the toe-in to the center of the specified range.
