REAR 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:


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


  1. INSPECT TIRES


    1. Check the tires for wear and proper inflation pressure.

      Cold Tire Inflation Pressure
      Tire Size

      Front

      kPa (kgf/cm2, psi)

      Rear

      kPa (kgf/cm2, psi)

      P205/65R16 94S

      P215/55R17 93V

      		 240 (2.4, 35)
    2. A01I56Z

      Using a dial indicator, check the runout of the tires.

      Maximum tire runout
      1.4 mm (0.0551 in.)

  2. MEASURE VEHICLE HEIGHT

    A01I2QPE01

    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 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.

    2. Measure the vehicle height.


        Measurement points:

      • A: Ground clearance of front wheel center


      • B: Ground clearance of lower No. 2 suspension arm bushing set bolt center


      • C: Ground clearance of rear wheel center


      • D: Ground clearance of outer strut rod set bolt center

      Vehicle Height (Unloaded Vehicle)
      Model Front A - B Rear C - D
      AVV50L-CEXNBA 123 mm (4.84 in.) 52 mm (2.05 in.)
      AVV50L-CEXGBA

      126 mm (4.96 in.)

      126 mm (4.96 in.)*A

      56 mm (2.20 in.)

      55 mm (2.17 in.)*A
      AVV50L-CEXSBA 125 mm (4.92 in.) 55 mm (2.17 in.)

      *A: for Korea

  3. INSPECT CAMBER

    Note

    Inspect while the vehicle is unloaded.

      *a Camber-caster-kingpin Gauge

      Install a camber-caster-kingpin gauge.

    2. Inspect the camber.

      Camber (Unloaded Vehicle)
      Model Camber Inclination Right-left Difference
      AVV50L-CEXNBA -1.21° +/- 0.75° (-1°13' +/- 0°45') 0.75° (0°45') or less
      AVV50L-CEXGBA -1.26° +/- 0.75° (-1°16' +/- 0°45')
      AVV50L-CEXSBA -1.26° +/- 0.75° (-1°16' +/- 0°45')

      Tech Tips

      Camber is not adjustable. If the measurement is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.

  4. 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 A)

      *a Tread Center Mark
      *b Dimension B
      A01I3Q9 Front of the Vehicle

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

    5. Slowly push the vehicle straight ahead to cause the rear wheels to rotate 180°. Use the rear 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 A again.

    6. A01I333E06

      *a Dimension A
      A01I3Q9 Front of the Vehicle

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

      Toe-in (Unloaded Vehicle)
      Specified Condition
      C + D: 0.21° +/- 0.17° (0°13' +/- 0°10')
      B - A: 2.5 +/- 2.0 mm (0.0984 +/- 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 rear No. 2 suspension arms.

  5. ADJUST TOE-IN


    1. A01I5WZ

      Measure the lengths of the right and left rear No. 2 suspension arms.

      Standard difference
      1.5 mm (0.0591 in.) or less
    2. A01I4II

      Loosen the 2 lock nuts.

    3. If the length difference between the left and right rear No. 2 suspension arm assemblies is not within the specified range, adjust it by following the procedures below.


      1. If the toe-in measurement is greater than the specified range (too much toe-out), extend the shorter rear No. 2 suspension arm by rotating the adjusting tube 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 rear No. 2 suspension arm by rotating the adjusting tube so that the length difference is within the specified range.

      3. Measure the toe-in.

    4. Turn the right and left adjusting tubes by an equal amount to adjust toe-in.

      Tech Tips


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

      • One turn of each adjusting tube will adjust the toe-in by approximately 11.3 mm (0.445 in.).

    5. Tighten the lock nuts while securing the adjusting tube in the order indicated below:


      1. Tighten the outside lock nut.

      2. Tighten the inside lock nut.

      3. Retighten the outside lock nut.

      Torque:
      56 N*m  { 570 kgf*cm, 41 ft.*lbf }

  6. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

  7. PERFORM YAW RATE AND ACCELERATION SENSOR CALIBRATION
