      36.67° (34.67° to 37.67°) 32.88°

      If the wheel angles differ from the standard of the specification, inspect the toe-in.

  6. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION 
    1. Install the camber-caster-kingpin gauge or position vehicle on wheel alignment tester.

    2. Inspect the camber, the caster and the steering axis inclination.

      Camber, caster and steering axis inclination: 

      2WD Except air suspension 

      2WD EXCEPT AIR SUSPENSION SPECIFIED CONDITION

      Area Specified Condition
      Camber   -0°28' +- 45' (-0.47° +- 0.75°)
      Right-left error 45' (0.75°) or less
      Caster   3°23'+-45'(3.38°+-0.75°)
      Right-left error 45'(0.75°) or less
      Steering axis Inclination   12°58' +- 45' (12.97° +- 0.75°)
      Right-left error 45'(0.75°) or toss

      2WD Air suspension 

      2WD AIR SUSPENSION SPECIFIED CONDITION

      Area Specified Condition
      Camber   -0°30'+-45'(-0.50°+-0.75°)
      Right-left error 45'(0.75°) or less
      Caster   3°33' +- 45' (3.55° +- 0.75°)
      Right-left error 45' (0.75°) or less
      Steering axis Inclination   13° 00' +- 45' (13.00° +- 0.75°)
      Right-left error 45' (0.75°) or less

      4WD Except air suspension 

      4WD EXCEPT AIR SUSPENSION SPECIFIED CONDITION

      Area Specified Condition
      Camber   -0°09' +- 45' (-0.15° +- 0.75°)
      Right-left error 45' (0.75°) or less
      Caster   3°13'+-45' (3.22°+-0.75°)
      Right-left error 45' (0.75°) of less
      Steering axis Inclination   12°39'+- 45' (12.65° +- 0.75°)
      Right-left error 45' (0.75°) or less

      4WD Air suspension 

      2WD AIR SUSPENSION SPECIFIED CONDITION

      Area Specified Condition
      Camber   -0°10' +-45' (-0.17° +-0.75°)
      Right-left error 45' (0.75°) or less
      Caster   3°22'+-45' (3.37° +- 75°)
      Right-left error 45' (0.75°) or less
      Steering axis Inclination   12°40' +- 45' (12.67° +- 0.75°)
      Right-left error 45' (0.75°) or less

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

  7. ADJUST CAMBER AND CASTER 
    NOTE: After the camber has been adjusted, inspect the toe-in.
    1. Loosen the nut and bolt.
    2. Turn the camber adjust cam No. 2 and toe adjust plate No. 2 in the circumference direction, and adjust the camber and the caster.

      HINT

      Try to adjust the camber-and caster to the center value.

    3. How to read adjustment chart (using examples).
      Fig 7: Example Of Adjustment Chart
      G04964555Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      1. Measure the present alignment.

        Camber: 0°15' (0.25°) 

        Caster: 2°45' (2.75°) 

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

        Standard value: 

        Camber: 0°35' (0.58°) 

        Caster: 2°55' (2.92°) 

        Formula: B - A = C 

        Camber: 0°15'- (0 35') = -0°20' 

        Caster: 2°45' - (2°55') = -0°10' 

      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.

        Toe adjust cam: - (Shorter) 2.8 

        Camber adjust cam: - (Shorter) 1.8
