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 (0.04 ± 0.08 inch)

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 (38 ± 1 ft-lb)
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


Required Special Tool:
  • MB991004: Wheel Alignment Gauge Attachment
    <Vehicles with aluminum wheels>
Standard value:

    Camber - 0°05’ ± 0°30’ (Left/right deviation within 30’)
    Caster 2°40’ ± 0°30’ (Left/right deviation within 30’)
    Kingpin inclination 13°30’ ± 1°30’
note Camber and caster are preset at the factory and cannot be adjusted.
caution Never subject the wheel bearings to the vehicle load when the drive shaft nuts are loosened.

note For vehicles with aluminum type wheels, attach the camber/caster/kingpin gauge to the driveshaft by using the special tool MB991004. Tighten the special tool MB991004 to the same torque 144 - 176 N·m (106 - 130 ft-lb) as the driveshaft nut.
