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:


  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.

  1. INSPECT REAR SUSPENSION


    1. A015YH2

      Inspect the rear suspension member.


      1. Measure the distance between the centers of the installation bolts of the rear No. 2 suspension arm assembly LH and RH.

        Standard
        508.6 to 514.6 mm (20.02 to 20.25 in.)

        If the distance is not within the specified range, replace the rear suspension member.

      2. A0160NF

        Visually inspect the press holes on the installation area of the rear upper No. 2 control arm assembly.

        Standard
        The holes are not deformed.

        If the holes are deformed, replace the rear suspension member.

    2. A0160W8

      Inspect the rear No. 2 suspension arm assembly.


      1. Measure the distance between the centers of the 2 installation bolts of the rear No. 2 suspension arm assembly.

        Standard
        433.4 to 434.4 mm (17.063 to 17.102 in.)

        If the distance is not within the specified range, replace the rear No. 2 suspension arm assembly.

    3. A0163KG

      Inspect the rear upper No. 2 control arm assembly.


      1. Measure the distance between the centers of the installation bolt of the rear upper No. 2 control arm assembly and the ball joint stud.

        Standard
        307.3 to 308.7 mm (12.099 to 12.153 in.)

        If the distance is not within the specified range, replace the rear upper No. 2 control arm assembly.

    4. Inspect and adjust the toe-in and camber.


      1. Inspect the toe-in and camber.

        If the values are not within the specified ranges, adjust the installation bolt holding the rear suspension member to the vehicle body, or the bolt holding the upper control arm and rear suspension arm so that the values fall within the specified ranges.

  2. INSPECT TIRES


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

      Cold Tire Inflation Pressure
      Tire Size

      Cold Tire Inflation Pressure

      kPa (kgf/cm2, psi)
      Front Rear Front Rear
      225/40R19 93Y 255/35R19 96Y

      320 (3.2, 46)*1

      300 (3.0, 44)*2

      250 (2.5, 36)*3

      *1: For driving at over 250 km/h (155 mph).

      *2: For driving at 210 km/h (131 mph) to 250 km/h (155 mph).

      *3: For driving at under 210 km/h (131 mph).

    2. A0162H4

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

      Maximum tire runout
      1.0 mm (0.0394 in.)

  3. MEASURE VEHICLE HEIGHT


    1. A015ZULE01

      Bounce the vehicle at the corners up and down to stabilize the suspension and inspect the 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 required to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.

      Vehicle Height
      Front A-B Rear C-D
      131.7 mm (5.19 in.) 107.1 mm (4.22 in.)
      Measuring points
      A
      Ground clearance of front wheel center.
      B
      Ground clearance of front center position of front suspension lower arm assembly front bushing installation bolt head.
      C
      Ground clearance of rear wheel center.
      D
      Ground clearance of rear center position of rear No. 2 suspension arm assembly bushing installation bolt threads.

  4. INSPECT TOE-IN

    A016123E23
    Toe-in
    Toe-in (Total)

    C + D: 0°16' +/- 10' (0.26°+/- 0.17°)

    B - A: 3 +/- 2 mm (0.118 +/- 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, inspect the suspension parts and replace parts if necessary.

  5. ADJUST TOE-IN


    1. A0161FM

      Loosen the toe adjust cam nut.

    2. Turn the adjust cams by an equal amount to adjust the toe-in.

      Tech Tips


      • Try to adjust the toe-in to the center value.

      • The toe-in will change by the following amount corresponding to each graduation of the cam:

        Approx. 4.0 mm (0.16 in.)

    3. Tighten the nut.

      Torque:
      50 N*m  { 510 kgf*cm, 37 ft.*lbf }

  6. INSPECT CAMBER


    1. A015Z33E06

      Install a camber-caster-kingpin gauge or put the rear wheels on a wheel alignment tester.

    2. Inspect the camber.

      Camber
      Camber Angle
      -1°30' +/- 45' (-1.50° +/- 0.75°)

      Note


      • Inspect while the vehicle is unloaded.

      • The maximum tolerance of right and left difference for the camber is 30' (0.5°) or less.

      If the measured value is not within the specified range, inspect the suspension parts for damage and wear. Replace parts as necessary because camber cannot be properly adjusted with any damaged or worn parts.

  7. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

  8. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    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 Click here.
