FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT

Required Special Tool:
^ MB991004: Wheel Alignment Gauge Attachment.

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

TOE-IN
Standard value: 2.5 ± 2.5 mm (0.1 ± 0.1 inch)





1. Adjust the toe-in by undoing the bellows clip and turning the left and right tie rod turn buckles 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. Use a turning radius gauge to check that the steering angle is at the standard value.

CAMBER AND CASTER





Standard value:
Camber: 0°00' ± 30' (difference between right and left wheels: within 30')
Caster: 3°31' ± 1° (difference between right and left wheels: within 30')
If the standard value is not obtained, make adjustment by the following procedure.





1. Adjust the camber and caster until they meets the standard value by turning the lower arm camber adjusting bolt according to the camber and caster reference table.
2. After adjusting the camber, the toe should be adjusted.

Camber and caster reference table
How to read this table (example)








If the camber difference -0°35' and the caster difference is 0°18' by comparing the measurement value with the standard value, rotate the front adjusting cam by 1.5 graduations and the rear adjusting cam by 2.5 graduations to the opposite direction against the "A" direction.

NOTE: Solid lines show caster, broken lines show camber.

UPPER ARM BALL JOINT END PLAY CHECK
