FRONT WHEEL ALIGNMENT ADJUSTMENT

CAUTION / NOTICE / HINT

Note

If a wheel alignment has been performed, 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:


  • Perform zero point calibration of the yaw rate and acceleration sensor.

PROCEDURE


  1. INSPECT TIRES

  2. MEASURE VEHICLE HEIGHT

    B001KZ4E02

    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.

    • The standard value shown here is a value that is used for performing a 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.

    2. Measure the vehicle height.


        Measurement Points:

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


      • B: Ground clearance of rear No. 2 suspension arm 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. B001LEU

      Remove the 2 nuts on the lower side of the front shock absorber.

      Note

      Keep the bolts inserted.

    3. Remove the top and bottom bolts one at a time and confirm that the steering knuckle can move freely in the shock absorber.

      Tech Tips


      • Reinstall each bolt after removing it and confirming steering knuckle movement.

      • If the steering knuckle does not move freely in the shock absorber, clean the installation surfaces of the front shock absorber and the steering knuckle.

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

    5. B001M3J

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

    6. B001LEU

      Tighten the 2 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. B001KMXE05

      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.

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

      The body and suspension may be damaged if the camber cannot be correctly adjusted according to the table above.

      Note

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


      1. Table (1) (To move the axle hub toward the positive side)

        *e 90105-17017 *f 90105-17018

    9. If the camber was out of adjustment in the previous step, perform the adjust camber steps mentioned above. In step A, replace the existing bolts with the 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)

    4. B001LSNE29
      Text in Illustration
      *a Tread Center Mark
      *b 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.

    6. B001KEQE24
      Text in Illustration
      *a Dimension A
      B001KHV Front of the Vehicle

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

      Toe-in (Unloaded Vehicle)
      Specified Condition
      C + D: 0°12' +/- 0°12' (0.20° +/- 0.20°)
      B - A: 2.0 +/- 2.0 mm (0.0787 +/- 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.

  6. ADJUST TOE-IN


    1. B001L5FE07
      Text in Illustration
      *a Thread Length

      Make sure that the thread length of the right and left rack ends are approximately the same.

      Standard Difference
      1.5 mm (0.0591 in.) or less

    2. Remove the boot clips.

    3. B001MM5

      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.

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

    7. Tighten the tie rod end lock nuts.

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

    8. Place the boots on the seats and install the clips.

      Note

      Make sure that the boots are not twisted.

  7. INSPECT WHEEL ANGLE

      *a Inside
      *b Outside
      B001KHV Front of the Vehicle

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

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

      Note

      Inspect while the vehicle is unloaded.

      (for sport)

      		 39°15' +/- 2°00' (39.25° +/- 2°) 32°53' (32.88°)

      • If the right and left inside wheel angles differ from the specified value, check and adjust the right and left rack end lengths.

  8. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

  9. PERFORM YAW RATE AND ACCELERATION SENSOR CALIBRATION
