Adjustment [09/2014 - 11/2017]: Procedure

  1. INSPECT TIRES 

    Refer to PROCEDURE - Step 1

  2. MEASURE VEHICLE HEIGHT 

    See step  2

  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
      for 2WD w/o Dynamic Rear Steering -1°52' +/- 0°45' (-1.87° +/- 0.75°) 0°45' (0.75°) or less
      w/ Dynamic Rear Steering -1°53' +/- 0°45' (-1.88° +/- 0.75°)
      for AWD - -1°53' +/- 0°45' (-1.88° +/- 0.75°)

      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.

  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. 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.

      HINT: 

      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. 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°11' +/- 0°11' (0.18° +/- 0.18°)
      B - A: 2.0 +/- 2.0 mm (0.0787 +/- 0.0787 in.)

      HINT: 

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

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

    2. Rotate the 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.)
      GTY518629Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      HINT: 

      • Rotating the 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 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. 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 difference in length 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 difference in length 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)

      HINT: 

      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.
