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. Testing and Inspection). [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 clip and jam 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 clip and tighten the jam nut to the specified torque.
Tightening torque: 52 ± 2 Nm (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 Steering Angle Check).

Required Special Tool:
- MB991004: Wheel Alignment Gauge Attachment
Vehicles with aluminum wheels

Camber 0°20' ± 0°30' (Left/right deviation within 0°30')
Caster 2°35' ± 0°30' (Left/right deviation within 0°30')
Kingpin inclination 12°45' ± 1°30'
NOTE:

CAUTION:
Do not apply the vehicle weight to the wheel bearing while loosening the driveshaft nut.
NOTE:
