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

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.
Standard value: 1 ± 2 mm
2.After adjustment, check that the steering angle is within the standard range using the turning radial gauge. (Refer to GROUP 37 On-vehicle Service).
Standard value:
Inner wheel
 38°40’ ± 1°30’
Outer wheel <Reference value>
 32°20’

CAMBER·CASTER

CAMBER
Standard value: 0°20’ ± 0°30’ (left/right difference 30’max)

CASTER
Standard value: 2°35’ ± 0°30’ (left/right difference 30’max)
note The camber and the caster are pre-adjusted at factory and not adjustable.
caution Do not apply the vehicle weight to the wheel bearing while loosening the driveshaft nut.

note For vehicles with aluminium wheels, tighten special tool wheel alignment gauge attachment (MB991004) to the specified torque, then measure the camber.
Tightening torque: 144 - 176 N·m
