FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT


caution After the installation, 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>

Measure wheel alignment with alignment equipment on a level surface. The front suspension, steering system, wheels, and tires should be serviced to normal condition before measuring wheel alignment.

TOE-IN


Standard value: 1 ± 2 mm

1.Adjust the toe-in by undoing the bellows clip and lock nut, and turning the left and right tie rod turnbuckles by the same amount (in opposite directions).
note The toe will move out as the left turnbuckle is turned toward the front of the vehicle and the right turnbuckle is turned toward the rear of the vehicle.
2.Install the bellows clip and tighten the lock nut to the specified torque.
Tightening torque: 52 ± 2 N·m
3.Confirm that the toe-in is at the standard value.
4.Use a turning radius gauge to check that the steering angle is at the standard value.
Standard value:
Inner wheel
40°50’ ± 1°30’
Outer wheel
(reference value)
33°50’

CAMBER, CASTER AND KINGPIN INCLINATION



CAMBER


Standard value:
    - 0°05’ ± 0°30’ <Standard suspension, sporty suspension> (Left/right deviation within 30’)
    0°10’ ± 0°30’ <High-ground suspension> (Left/right deviation within 30’)

CASTER


Standard value:
    2°40’ ± 0°30’ <Standard suspension, sporty suspension> (Left/right deviation within 30’)
    2°30’ ± 0°30’ <High-ground suspension> (Left/right deviation within 30’)
note The camber and the caster are pre-adjusted at factory and not adjustable.

KINGPIN INCLINATION


Standard value:
    13°30’ ± 1°30’
    <Standard suspension, sporty suspension>
    13°10’ ± 1°30’
    <High-ground suspension>
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
