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

      HINT: Make sure that the boots are not twisted.

    7. Perform VSC system calibration
  5. INSPECT WHEEL ANGLE 
    1. Turn the steering wheel fully, and measure the turning angle.

    Wheel angle: 

    2WD 

    WHEEL ANGLE - 2WD

    Inside wheel 37°00' (35°00' - 38°00')
    37.00° (35.00° - 38.00°)
    Outside wheel (Reference) 32° 30'
    32.50°

    4WD: 

    WHEEL ANGLE - 4WD

    Inside wheel 36°40' (34° 40' - 37° 40')
    36.67° (34.67° - 37.67°)
    Outside wheel (Reference) 32° 53'
    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: 

    CASTER AND STEERING AXIS INCLINATION

    Camber  
    Right-left error    		 -0° 28' +/- 45' (-0.47° +/- 0.75°) 45' (0.75°) or less
    Caster  
    Right-left error    		 3° 23' +/- 45' (3.38° +/- 0.75°) 45' (0.75°) or less
    Steering axis inclination  
    Right-left error    		 12° 58' +/- 45' (12.97° +/- 0.75°) 45' (0.75°) or less

    2WD Air suspension: 

    CASTER AND STEERING AXIS INCLINATION - 2WD AIR SUSPENSION

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

    4WD Except air suspension: 

    CASTER AND STEERING AXIS INCLINATION - 4WD EXCEPT AIR SUSPENSION:

    Camber  
    Right-left error    		 -0°09' +/- 45' (-0.15° +/- 0.75°) 45' (0.75°) or less
    Caster  
    Right-left error    		 3°13' +/- 45' (3.22° +/- 0.75°) 45' (0.75°) or less
    Steering axis inclination  
    Right-left error    		 12°39' +/- 45' (12.65° +/- 0.75°) 45' (0.75°) or less

    4WD Air suspension: 

    CASTER AND STEERING AXIS INCLINATION - 4WD AIR SUSPENSION

    Camber  
    Right-left error    		 -0°10' +/- 45' (-0.17° +/- 0.75°) 45' (0.75°) or less
    Caster  
    Right-left error    		 3° 22' +/- 45' (3.37° +/- 0.75°) 45' (0.75°) or less
    Steering axis inclination  
    Right-left error    		 12°40' +/- 45' (12.67° +/- 0.75°) 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).
      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 Fig 8 , 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
