Alignment: Service and Repair

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: 1 ± 2 mm (0.04 ± 0.09 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.
Standard value: 40 ± 5 Nm (30 ± 3 ft. lbs.)
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





Standard value

CAMBER, CASTER AND KINGPIN INCLINATION
Standard value:
Camber 0°00' ± 30' (Left/right deviation within 30')
Caster 2°50' ± 30' (Left/right deviation within 30')
Kingpin inclination 12°35' ± 1° 30'

CAUTION: Never subject the wheel bearings to the vehicle load when the drive shaft nuts are loosened.

NOTE: Camber and caster are preset at the factory and cannot be adjusted.





For vehicles with aluminum type wheels, attach the camber/caster/kingpin gauge to the driveshaft by using special tool MB991004. Tighten special tool MB991004 to the same torque 245 ± 29 Nm (181 ± 21 ft. lbs.) as the driveshaft nut.
