FRONT WHEEL ALIGNMENT ADJUSTMENT

Note

If the wheel alignment has been adjusted, or 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. Disconnect the cable from the negative battery terminal for more than 2 seconds.

  2. Reconnect the cable to the negative battery terminal.

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

  1. INSPECT FRONT SUSPENSION


    1. A01633B

      Inspect the front suspension member.


      1. Measure the dimension between the center of the installation bolts of the front lower suspension arm.

        Standard
        692.5 to 699.5 mm (2.27 to 2.30 ft.)

        If the result is not within the specification, replace the front suspension member.

    2. A015YQ5E01

      Inspect the front lower suspension arm assembly.


      1. Remove the front lower suspension arm assembly Click here.

      2. Measure the dimension between the center of the front lower suspension arm assembly bush and the center of position A.

        Standard
        362 to 364.6 mm (1.19 to 1.20 ft.)

        If the dimension of the front lower suspension arm assembly changes 2 mm (0.079 in.), the camber will change approximately 15' (0.25°).

    3. A015Z9IE01

      Inspect the front upper suspension arm assembly.


      1. Remove the front upper suspension arm assembly Click here.

      2. Measure the dimension between the center of the front upper suspension arm assembly bush and the center of the ball joint stud.

        Standard
        A
        241 to 242.6 mm (9.49 to 9.55 in.)
        B
        215.1 to 216.7 mm (8.47 to 8.53 in.)

        If the dimension of the front upper suspension arm assembly changes 2 mm (0.0787 in.), the camber will change approximately 15' (0.25°).

  3. MEASURE VEHICLE HEIGHT


    1. A015ZULE01

      Bounce the vehicle at the corners up and down to stabilize the suspension and inspect the 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 required to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.

      Vehicle Height
      Front A-B Rear C-D
      131.7 mm (5.19 in.) 112.1 mm (4.41 in.)
      Measuring points
      A
      Ground clearance of front wheel center.
      B
      Ground clearance of front center position of front suspension lower arm assembly front bushing installation bolt head.
      C
      Ground clearance of rear center position of rear No. 2 suspension arm bushing installation bolt threads.
      D
      Ground clearance of rear center position of rear suspension lower arm assembly rear bushing installation bolt head.

  4. INSPECT WHEEL ANGLE


    1. Put tread center marks on the rearmost points of the turning radius gauge.

    2. A01619SE03

      Turn the steering wheel fully left and right and measure the turning angle.

      Wheel Turning Angle
      Inside Wheel Outside Wheel (Reference)
      41°48' +/- 2° (41.8° +/- 2°) 35°48' (35.8°)

      If the right and left inside wheel angles differ from the specified range, check the lengths of the right and left rack ends.

  5. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION


    1. A015Z33E06

      Place a front wheel on the center of the turning radius gauge.

    2. Remove the center ornament.

    3. Install the camber-caster-kingpin gauge at the center of the axle hub or drive shaft.

    4. Inspect the camber, caster, and steering axis inclination.

      Camber, Caster, and Steering Axis Inclination
      Camber Angle Caster Angle Steering Axis Inclination Angle

      -0°52' +/- 45'

      (-0.87° +/- 0.75°)

      8°42' +/- 45'

      (8.70° +/- 0.75°)

      11°11' +/- 45'

      (11.18° +/- 0.75°)

      Note


      • Inspect while the vehicle is unloaded.

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

    5. Remove the camber-caster-kingpin gauge.

    6. Install the center ornament.

      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 damaged and/or worn out parts.

  6. ADJUST CASTER


    1. According to the cater measurement, select a lower No. 2 arm bracket.

      Bracket Part No.
      Bracket Part No. Installation Position Offset Angle
      48075-30020 RH 0(Standard)
      48075-53020 RH +20'
      48075-53030 RH -20'
      48076-30020 LH 0(Standard)
      48076-53020 LH +20'
      48076-53030 LH -20'

  7. 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 N.

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

    4. A016349E07

      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 a front tire pressure 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 *1 again.

    6. A015ZYPE12

      Measure the distance between the tread center marks on the front side of the wheels (dimension A).

      Toe-in
      Toe-in (Total)

      C + D: 0°01' +/- 10' (0.02°+/- 0.17°)

      B - A: 0.18 +/- 2 mm (0.00709 +/- 0.0787 in.)

      Tech Tips

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

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

  8. ADJUST TOE-IN


    1. A015YTU

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

      Standard
      Difference in thread length is 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. Shorten the longer rack end if the measured toe-in deviates toward the outer-side.

      2. Extend the shorter 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 toe-in.

      Tech Tips

      Try to adjust 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.

      Torque:
      56 N*m  { 571 kgf*cm, 41 ft.*lbf }

      Note

      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 notches on the tie rod end and tighten the lock nut.

    8. Place the boots on the seats and install the rack boot set clips.

      Tech Tips

      Make sure that the boots are not twisted.

  9. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

  10. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    Disconnect the cable from the negative battery terminal for more than 2 seconds.

  11. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
