33-FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT

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

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.

TOTAL TOE-IN

Standard value: 1 ± 2 mm (0.04 ± 0.08 inch)

1. Adjust the total toe-in by undoing the bellows 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 bellows clip and tighten the jam nut to the specified torque.

Tightening torque: 52 ± 2 N·m (38 ± 1 ft-lb)

3. Confirm that the total toe-in is at the standard value.

4. Use a turning radius gauge to check that the steering angle is at the standard value (Refer to GROUP 37 - On-vehicle Service, Steering Angle Check

CAMBER, CASTER AND KINGPIN INCLINATION

Required Special Tool:

MB991004: Wheel Alignment Gauge Attachment
<Vehicles with aluminum wheels>

Standard value:

Camber: 0°20' ± 0°30' (Difference between right and left wheels must be 0°30' or less.)
Caster: 2°45' ± 0°30' (Difference between right and left wheels must be 0°30' or less.)
Kingpin inclination: 12°45' ± 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 (107 - 129 ft-lb) as the driveshaft nut.
