REAR WHEEL ALIGNMENT INSPECTION

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.


  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)
      195/65R15 91H 250 (2.5, 36) 240 (2.4, 35)
    2. A0040ZR

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

      Maximum tire runout
      1.4 mm (0.0551 in.)

  2. MEASURE VEHICLE HEIGHT

    A00442RE01

    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:

      • A: Ground clearance of front lower No. 1 suspension arm bushing set bolt center


      • B: Ground clearance of rear axle beam bushing set bolt center


      • C: Ground clearance of front wheel center


      • D: Ground clearance of rear wheel center

      Vehicle Height (Unloaded Vehicle)
      Front C - A Rear D - B
      106 mm (4.17 in.) 25 mm (0.984 in.)

  3. INSPECT CAMBER

    Note

    Inspect while the vehicle is unloaded.


    1. Install a camber-caster-kingpin gauge.

    2. Inspect the camber.

      Camber (Unloaded Vehicle)
      Camber Inclination Right-left Difference
      -1°29' +/- 0°30' (-1.48° +/- 0.50°) 0°30' (0.50°) or less

      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)

      A00407B 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.

      *a Dimension A
      A00407B Front of the Vehicle

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

      Toe-in (Unloaded Vehicle)
      Specified Condition Right-left Difference
      C + D: 0°17' +/- 0°18' ( 0.28° +/- 0.30°) 0°45' (0.75°) or less
      B - A: 2.8 +/- 3.0 mm (0.110 +/- 0.118 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 them if necessary.
