Adjustment [08/2013 - 04/2014]: Procedure

  1. INSPECT TIRES 

    Refer to PROCEDURE - Step 1

  2. MEASURE 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 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: 

      1. A: Ground clearance of front lower suspension arm bushing set bolt center
      1. B: Ground clearance of rear trailing arm bushing set bolt center
      1. C: Ground clearance of front wheel center
      1. D: Ground clearance of rear wheel center

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

      HINT: 

      • Reinstall each bolt after removing it and confirming steering knuckle movement.
      • If the steering knuckle does not move freely in the front shock absorber assembly, clean the installation surfaces of the front shock absorber assembly and the steering knuckle.
    5. Temporarily install the 2 nuts. (Step A)
    6. Fully push or pull the front axle hub in the direction of the required adjustment. (Step B)

    7. Tighten the 2 nuts.

      Torque: 240 N*m (2447 kgf*cm, 177 ft.*lbf) 

      NOTE:

      Keep the bolts from rotating when tightening the nuts.

    10. Install the front wheel.

      Torque: 102.9 N*m (1049 kgf*cm, 76 ft.*lbf) 

    11. 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.

      HINT: 

      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.

    12. 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.

      HINT: 

      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 (for CVT and Automatic Transaxle).
    3. Release the parking brake and move the shift lever to neutral (for Manual Transaxle).
    4. Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)
    5. Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

      *a Tread Center Mark
      *b Dimension B

    6. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180°. Use 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 step C again.

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

      Toe-in (Unloaded Vehicle)

      Specified Condition
      C + D: 0°00' +/- 0°12' (0.00° +/- 0.20°)
      B - A: 0 +/- 2.0 mm (0 +/- 0.0787 in.)

      HINT: 

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

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

  6. ADJUST TOE-IN 
    1. Make sure that the thread length of the right and left steering rack ends are approximately the same.

      Standard Difference

      1.5 mm (0.0591 in.) or less

    4. Adjust the steering rack ends if the difference in thread length between the right and left steering rack ends is not within the specified range.
      1. If the toe-in measurement is greater than the specified range (too much toe-out), extend the shorter rack end so that the length difference is within the specified range.
      2. If the toe-in measurement is less than the specified range (too much toe-in), shorten the longer rack end so that the length difference is within the specified range.
      3. Measure the toe-in.
    5. Turn the right and left steering rack ends by an equal amount to adjust the toe-in.
    6. Make sure that the thread length of the right and left steering rack ends are the same.
    7. Tighten the tie rod end sub-assembly lock nuts.

      Torque: 74 N*m (755 kgf*cm, 55 ft.*lbf) 

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

      HINT: 

      Make sure that the steering rack boots are not twisted.

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

      *2: except Mexico

      1. If the right and left inside wheel angles differ from the specified value, check and adjust the right and left steering rack end lengths.
  8. PLACE FRONT WHEELS FACING STRAIGHT AHEAD
