FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT


caution Perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point (Refer to GROUP 35C, On-vehicle Service - Steering Wheel Sensor Calibration ) <Vehicles with ASC>.

  • Before the wheel alignment measurement, maintain the front suspension, the steering system and the wheel tyres in good condition.
  • Park the vehicle on a level surface, and position the front wheel in the straight- ahead position to measure the wheel alignment.

TOE-IN


Standard value:

    At the centre of tyre tread: 1 ± 2 mm
    Toe-angle (per wheel): 0°02’ ± 0°04’

1.Loosen the lock nut with tie-rod bellows clip removed, and then perform the adjustment by turning the tie-rod left/right at the same degree in the opposite direction.
note The toe moves to the outside by turning the tie-rod: left to the forward direction, and right to the reverse direction.
2.After adjustment, check that the steering angle is within the standard range using the turning radial gauge (GROUP 37 - On-vehicle Service, Steering Angle Check ).

CAMBER·CASTER AND KINGPIN INCLINATION



CAMBER


Standard value: 0°20’ ± 0°30’

CASTER


Standard value: 2°35’ ± 0°45’
note
  • Difference between right and left wheels must be 0°30’ or less.
  • The camber and the caster are pre-adjusted at factory and not adjustable.

KINGPIN INCLINATION


Standard value: 12°45’ ± 1°30’

caution Do not apply the vehicle weight to the wheel bearing while loosening the driveshaft nut.

note
  • The camber is pre-adjusted at factory and is not adjustable.
  • As for vehicles with aluminium wheel, use a compensator to measure the camber and caster.
