    NOTICE:
    1. Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
    2. Be sure to perform measurement on a level surface.
    3. 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.


3. INSPECT TOE-IN
  1. Bounce the vehicle up and down at the corners to stabilize the suspension.

  1. Release the parking brake and move the shift lever to the neutral position.

  1. Push the vehicle straight ahead approximately 5 m (16.4 ft). (*1)



    C125225E02
  1. Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

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

    HINT:
    Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from *1 again.


    C125226E03
  1. Measure the distance between the tread center marks on the front side of the wheels.

    Toe-in:
    Toe-in
    (total)
    -
    A - B:
    0 +- 2 mm (0 +- 0.08 in.)

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


4. ADJUST TOE-IN


    C140712
  1. Measure the thread lengths of the right and left rack ends.

    Standard:
    Difference in thread length between the right and left rack ends is 1.5 mm (0.059 in.) or less.
  1. Remove the rack boot set clips.

  1. Loosen the tie rod end lock nuts.

  1. 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 outside.

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

  1. Turn the right and left rack ends by equal amounts to adjust the toe-in.

    HINT:
    Try to adjust the toe-in to the center of the specified range.
  1. Make sure that the lengths of the right and left rack ends are the same.

  1. Tighten the tie rod end lock nuts.

    Torque:
    74 N*m{ 755 kgf*cm , 55 ft.*lbf }

    NOTICE:
    Temporarily 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 width across flats on the tie rod end and tighten the lock nut.
  1. Place the boots on the seats and install the clips.

    HINT:
    Make sure that the boots are not twisted.


5. INSPECT WHEEL ANGLE
  1. Put tread center marks on the rearmost points of the turning radius gauge.

    Wheel turning angle:
    Inside wheel
    Outside wheel reference
    38°42' +- 2°(38.70°+- 2°)
    33°46' (33.77°)
    If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.


6. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION


    C132440E01
  1. Put the front wheel on the center of the alignment tester.

  1. Remove the center ornament.

    Camber:
    Camber
    Right-left difference
    -0°30' +- 45' (-0.50°+- 0.75°)
    45' (0.75°) or less

    Caster:
    Caster
    Right-left difference

    Steering axis inclination:
    Steering axis inclination
    Right-left difference
    12°00' +- 45' (12.00°+- 0.75°)
    45' (0.75°) or less

    NOTICE:
    1. Perform this inspection while the vehicle is unloaded.
    2. The maximum tolerance of the right and left difference for the camber and caster is 45' (0.75°) or less.
  1. Remove the camber-caster-king pin gauge and attachment.

  1. Install the center ornament.

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

    C140710E02

    C138332E01


    C138332E02

  1. Check the camber.
    If the measured value is not within the specification, calculate the required adjustment amount using the formula below.
    Camber adjustment amount = Specified range center - measured value
    Check the combination of installed bolts. Select appropriate bolts from the table below to adjust the camber to the specified values.

    HINT:
    Try to adjust the camber to the center of the specified values.
    Move the axle toward (+) in step (B)
    Move the axle toward (-) in step (B)
    Refer to table (1) (Move the axle toward positive side)
    Refer to table (2) (Move the axle toward negative side)
    The body and suspension may be damaged if the camber is not correctly adjusted according to the above table.

    NOTICE:
    Replace the nut with a new one when replacing the bolt.
  1. Repeat the steps mentioned above. In step (A), replace 1 or 2 selected bolts.

    HINT:
