  3. INSPECT TOE-IN

    A01KHUDE03
    Toe-in (A-B)
    4.0 +/- 2.0 mm (0.16 +/- 0.08 in.)

    If the toe-in is not within the specified range, adjust it at the rack ends.

  4. ADJUST TOE-IN


    1. Remove the rack boot set clips.

    2. Loosen the tie rod end lock nuts.

    3. Turn the right and left rack ends uniformly to adjust the toe-in.

      Toe-in (A-B)
      4.0 +/- 1.0 mm (0.16 +/- 0.04 in.)

      Tech Tips

      Try to adjust the toe-in to the middle of the specified range.

    4. A01KFYG

      Make sure that the lengths of the right and left rack ends are approximately the same.

      Standard difference
      0 +/- 1.0 mm (0 +/- 0.04 in.)

    5. Torque the tie rod end lock nuts.

      Torque:
      91 N*m  { 928 kgf*cm, 67 ft.*lbf }

    6. Place the boots on the seats and install the clips.

      Tech Tips

      Make sure that the boots are not twisted.

  5. INSPECT WHEEL TURNING ANGLE


    1. A01KG4HE22
      Text in Illustration
      *a Inside
      *b Outside
      A01KFFI Front

      Turn the steering wheel fully, and measure the wheel turning angle.

      Wheel turning angle
      Inside wheel

      Outside wheel

      (Reference)
      38° (36° to 39°) 36°

      If the right and left inside wheel turning angles differ from the specified range, check the right and left rack end lengths.

  6. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

    A01KHZDE25
    Text in Illustration
    *1 Alignment tester
    *2 Gauge

    1. Install the camber-caster-kingpin gauge and position the front wheel on the wheel alignment tester.

      Note

      The tolerance for the difference between the left and right wheels is 30' (0.50°) or less for both the camber and caster.

      If the camber and caster are not as specified, adjust them.

      If the steering axis inclination is not as specified after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for distortion and slack.

  7. ADJUST CAMBER AND CASTER

    Note

    Inspect the toe-in after the camber and caster have been adjusted.

      How to read the adjustment chart (using examples).


      1. Measure the present alignment.

        Camber
        1°00' (1.00°)
        Caster
        1°00' (1.00°)

      2. Calculate the difference between the standard value (A) and the measured value (B) on the adjustment chart.

        Standard value
        Camber
        0°30' (0.50°)
        Caster
        2°30' (2.50°)
        Formula
        B - A = C
        Camber
        1°00' - (0°30') = 0°30'
        Caster
        1°00' - (2°30') = -1°30'

      3. As shown in the chart, read the distance from the marked point to 0 point, and adjust the front and/or rear adjusting cams accordingly.
