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.
Standard value:
Inner wheels31_45’±1_30’
Outer wheels (for reference)27_15’
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:

NOTE
1. *: difference between right and left wheels must be less
than 30’
2. Caster and kingpin inclination are preset at the factory
and cannot be adjusted.
SELECTION THE CAMBER
Select the camber by the installation direction of the allow
of the connecting bolt of the strut assembly and the knuckle.

of vehicle inside.
D-2

BALL JOINT DUST COVER CHECK
1. Check the dust cover for cracks or damage by pushing
it with finger.
2. If the dust cover is cracked or damaged, replace the
lower arm assembly.
NOTE
Cracks or damage of the dust cover may cause damage
of the ball joint.
