Measure wheel alignment with alignment equipment
on a level surface. The front suspension, steering
system, wheels, and tyres should be serviced to nor-
mal condition before measuring wheel alignment.

TOE-IN

Standard value:

At the centre of tyre tread: 1

± 2 mm

Toe angle (per wheel): 0

° 03' ± 0° 06'

AC006074 AD

Lock nut

Clip

1. Adjust the toe-in by undoing the 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 clip and tighten the lock nut to the

specified torque.

Tightening torque: 40

± 5 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.

TOE-OUT ANGLE ON TURNS

To check the steering linkage, especially after the
vehicle has been involved in an accident or if an acci-
dent 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.

spring.

• Spring compressor body (MB991237)

• Arm set (MB991238)

WARNING

Do not use an impact wrench to remove the
strut nut (self-locking nut). Vibration of the
impact wrench will cause special tools
(MB991237 and MB991238) to slip and cause
personal injury.
