FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT


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

TOE-IN
Standard value:
    At the centre of tyre tread: 0 ± 3 mm
    Toe angle (per wheel): 0°00’ ± 0°08’

1.Adjust the toe-in by undoing the bellows clip and lock 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 lock nut to the specified torque.
Tightening torque: 52 ± 2 N·m
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

Inner wheels
 39°30’ ± 2°00’
Outer wheels (reference)
 32°30’

<VEHICLES WITH 17 INCH WHEEL>
Item

Inner wheels
 36°30’ ± 2°00’
Outer wheels (reference)
 30°50’

TOE-OUT ANGLE ON TURNS
To check the steering linkage, especially after the vehicle has been involved in an accident or if an accident is presumed, it is advisable to check the toe-out angle on turns in addition to the wheel alignment.
Conduct this test on the left turn as well as on the right turn.
Standard value:
Item
 Specification
Toe-out angle on turns (inner wheel when outer wheel at 20°)
 21°40’

CAMBER, CASTER AND KINGPIN INCLINATION
Standard value:
Item
 Specification
Camber
 0°00’ ± 0°30’* <Standard>, 0°10’ ± 0°30’* <High ground clearance suspension>
Caster
 2°46’ ± 1°00’* <Standard>, 2°41’ ± 1°00’* <High ground clearance suspension>
Kingpin inclination
 13°12’ ± 1°30’ <Standard>, 12°54’ ± 1°30’ <High ground clearance suspension>
note *: Difference between right and left wheels must be less than 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 driveshaft nuts are loosened.

note For vehicles with aluminium wheels, attach the camber/caster/kingpin gauge to the driveshaft by using special tool wheel alignment gauge attachment (MB991004). Tighten the special tool to the same torque 245 ± 29 N·m as the driveshaft nut.
