Front Suspension

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 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 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 [Vehicles without electrical power steering] or On-vehicle Service, Steering Angle Check Steering Angle Check [Vehicles with electrical power steering]).

CAMBER, CASTER AND KINGPIN INCLINATION

Required Special Tool:

- MB991004: Wheel Alignment Gauge Attachment
[Vehicles with aluminum wheels]

Standard value:

Camber: -0°05' ± 0°30' (Difference between right and left wheels must be 0°30' or less.)
Caster: 2°40' ± 0°30' (Difference between right and left wheels must be 0°30' or less.)
Kingpin inclination: 13°30' ± 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 Nm (106 - 130 ft-lb) as the driveshaft nut.
