Rear Wheel Alignment: Adjustment

NOTE: If the wheel alignment has been adjusted, and 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.

HINT:

(See CALIBRATION )

  1. INSPECT TIRES 
    1. Inspect the tires (See INSPECTION ).
  2. MEASURE VEHICLE HEIGHT  (See ADJUSTMENT  )
  3. INSPECT TOE-IN 

    Toe-in 

    TOE-IN SPECIFICATION

    Item Specified Condition
    Toe-in (2WD) (total) C + D: 0°10' +/- 0°12' (0.17° +/- 0.2°)
    B - A: 3.0 +/- 2.0 mm (0.12 +/- 0.08 in.)
    Toe-in (4WD) (total) C + D: 0°8' +/- 0°12' (0.14° +/- 0.2°)
    B - A: 3.0 +/- 2.0 mm (0.12 +/- 0.08 in.)

    If toe-in is not within the specified range, adjust it at the rear No. 2 suspension arms.

    HINT:

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

  4. ADJUST TOE-IN (for 2WD) 
    1. Measure the lengths of the right and left rear No. 2 suspension arms.

      Standard difference: 1.5 mm (0.06 in.) or less 

      If the left-right difference is larger than 1.5 mm (0.06 in.), adjust it by following the procedures below.

    2. 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.

      HINT:

      • Try to adjust toe-in to the center of the specified range.
      • One turn of each adjusting tube will adjust toe-in by approximately 11.1 mm (0.44 in.).
      1. If the toe-in measurement is greater than the specified range, extend the shorter rear No. 2 suspension arm assembly by rotating the adjusting tube in the direction of arrow B.
      2. If the toe-in measurement is less than the specified range, shorten the longer rear No. 2 suspension arm assembly by rotating the adjusting tube in the direction of arrow A.
      3. Measure the toe-in.
    4. Turn the right and left adjusting tubes by an equal amount to adjust toe-in.
    5. Tighten the 2 lock nuts.

      Torque: 56 N*m (571 kgf*cm, 41 ft.*lbf)

  5. ADJUST TOE-IN (for 4WD) 
    1. Measure the distance between each wheel disc and the center of the toe-adjusting cam, and then confirm that left and right distances are the same.

      Difference in the length of rear No. 2 suspension arms: 1.0 mm (0.04 in.) or less 

      If the left-right difference is larger than 1.0 mm (0.04 in.), adjust it by following the procedures below.

    2. Loosen the toe-adjust cam set nuts.
    3. Turn the adjust cams by an equal amount to adjust toe-in.

      HINT:

      • Try to adjust toe-in to the center of the specified range.
      • The toe-in will change by the following amount corresponding to each graduation of the cam. Approx. 3.3 mm (0.13 in.)
    4. Tighten the toe-adjust cam set nuts.

      Torque: 100 N*m (1019 kgf*cm, 74 ft.*lbf)

  6. INSPECT CAMBER 
    CAMBER SPECIFICATION

    - 2WD 4WD Right-left difference
    Camber -1°00' +/- 45' (-1.00° +/- 0 75°) -0°36' +/- 45' (-0.60° +/- 0 75°) 45' (0.75°) or less

    HINT:

    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.

  7. PLACE FRONT WHEELS FACING STRAIGHT AHEAD 
  8. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL 
    NOTE: When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See INITIALIZATION )

    HINT:

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

  9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL 
    NOTE: When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See INITIALIZATION ).
  10. PERFORM YAW RATE SENSOR ZERO POINT CALIBRATION 

    HINT:

    Perform yaw rate sensor zero point calibration (See CALIBRATION ).

  11. CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION 

    HINT:

    Check steering angle sensor zero point calibration (See DTC C1290 STEERING ANGLE SENSOR ZERO POINT MALFUNCTION ).
