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:

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

PROCEDURE


  1. INSPECT TIRES

  2. MEASURE VEHICLE HEIGHT

    Note


    • Before inspecting the wheel alignment, check the vehicle height.

    • 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.

      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.

      Note


      • Inspect while the vehicle is unloaded.

      • 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-kingpin gauge.

    6. Install the wheel cap.

  4. ADJUST CAMBER

    Note

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

    9. Install the front wheel.

      Torque:
      103 N*m  { 1050 kgf*cm, 76 ft.*lbf }
    10. A0046QHE01

      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)

      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.

      Note

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

      Tech Tips

      Measure "B - A" only when "C + D" cannot be measured.

      If the toe-in is not within the specified value, adjust it at the rack ends.

  6. ADJUST TOE-IN

    A004AK1

    1. Measure the thread lengths of the right and left rack ends.

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

    2. Remove the rack boot set clips.

    3. 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.

      Tech Tips

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

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

    7. Tighten the tie rod end lock nuts to the specified torque.

      Torque:
      75 N*m  { 760 kgf*cm, 55 ft.*lbf }

      Note

      Provisionally tighten the lock nut while holding the hexagonal part of the steering rack end so that the lock nut and the steering rack end do not turn together. Hold the flat of the tie rod end and tighten the lock nut.

    8. Place the boots on the seats.
