REAR 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.

  3. INSPECT CAMBER

    Note

    Inspect while the vehicle is unloaded.


    1. B00759JC10
      *a Camber-caster-kingpin Gauge

      Install a camber-caster-kingpin gauge.

    2. Inspect the camber.

      Camber (Unloaded Vehicle)
      - Tire Size Camber Inclination Right-left Difference
      w/o Dynamic Rear Steering for 17 inch -1°53' +/- 0°45' (-1.88° +/- 0.75°) 0°45' (0.75°) or less

      for 18 inch

      for 19 inch

      		 -1°52' +/- 0°45' (-1.87° +/- 0.75°)
      w/ Dynamic Rear Steering - -1°53' +/- 0°45' (-1.88° +/- 0.75°)

      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)

    4. B0076KWC02
      *a Tread Center Mark
      *b Dimension B
      B0073AQ 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. B007356C02
      *a Dimension A
      B0073AQ 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
      w/o Dynamic Rear Steering C + D: 0°11' +/- 0°11' (0.18° +/- 0.18°)
      B - A: 2.0 +/- 2.0 mm (0.0787 +/- 0.0787 in.)
      w/ Dynamic Rear Steering

      C + D: 0°11' +/- 0°11' (0.18° +/- 0.18°)

      C + D: 0°00' +/- 0°11' (0.00° +/- 0.18°)*

      B - A: 2.0 +/- 2.0 mm (0.0787 +/- 0.0787 in.)

      B - A: 0 +/- 2.0 mm (0 +/- 0.0787 in.)*

      *: for Korea

      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 toe control link sub-assembly or steering rack ends.

  5. ADJUST TOE-IN (w/o Dynamic Rear Steering)


    1. B007615

      Loosen the nut of the toe control link sub-assembly (on the rear suspension member sub-assembly side).

      Note

      Hold the rear suspension toe adjust cam sub-assembly while rotating the nut.

    2. B007613

      Rotate the rear suspension toe adjust cam sub-assembly to adjust the toe-in.

      Toe-in (Unloaded Vehicle)
      Specified Condition
      C + D: 0°11' +/- 0°11' (0.18° +/- 0.18°)
      B - A: 2.0 +/- 2.0 mm (0.0787 +/- 0.0787 in.)

      Tech Tips


      • Rotating the rear suspension toe adjust cam sub-assembly by one notch changes the toe by approximately 4.7 mm (0.185 in.).

      • Perform adjustments so that the value is as close as possible to the median of the specified range.

    3. Tighten the nut of the toe control link sub-assembly (on the rear suspension member sub-assembly side).

      Torque:
      117 N*m  { 1193 kgf*cm, 86 ft.*lbf }

      Note

      Hold the rear suspension toe adjust cam sub-assembly while rotating the nut.

  6. ADJUST TOE-IN (w/ Dynamic Rear Steering)

    Note

    If the rear steering link assembly or rear suspension is removed and installed, replaced, or adjusted, after performing actuator calibration value initialization, perform neutral position memorization and motor rotation angle sensor calibration.


    1. B007577

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

      Standard Difference
      1.5 mm (0.0591 in.) or less

    2. Remove the rear steering rack boot clips.

    3. Loosen the rear steering tie rod assembly lock nuts.

    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 steering 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 steering 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.

      Toe-in (Unloaded Vehicle)
      Specified Condition

      C + D: 0°11' +/- 0°11' (0.18° +/- 0.18°)

      C + D: 0°00' +/- 0°11' (0.00° +/- 0.18°)*

      B - A: 2.0 +/- 2.0 mm (0.0787 +/- 0.0787 in.)

      B - A: 0 +/- 2.0 mm (0 +/- 0.0787 in.)*

      *: for Korea

      Tech Tips

      Perform adjustments so that the value is as close as possible to the median of the specified range.

    6. Tighten the rear steering tie rod assembly lock nuts.

      Torque:
      55 N*m  { 561 kgf*cm, 41 ft.*lbf }

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