33-FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT

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

Before the wheel alignment measurement, maintain the front suspension, the steering system and the wheel tires 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

Standard value:

At the center of tire tread: 1 ± 2 mm (0.04 ± 0.08 inch)
Toe-in angle (per wheel): 0°02' ± 0°04'

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.

2. After adjustment, check that the steering angle is within the standard range using the turning radial gauge (GROUP 37 - On-vehicle Service, Steering Angle Check

CAMBER·CASTER AND KINGPIN INCLINATION

CAMBER

Standard value: 0°20' ± 0°30’ (Difference between right and left wheels must be 0°30' or less.)

CASTER

Standard value: 2°35' ± 0°30’ (Difference between right and left wheels must be 0°30' or less.)'

note	The camber and the caster are pre-adjusted at factory and not adjustable.

KINGPIN INCLINATION

Standard value: 12°45' ± 1°30'

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

note	The camber is pre-adjusted at factory and is not adjustable. As for vehicles with aluminum wheel, use a compensator to measure the camber and caster.
