1. Adjust the toe-in by undoing the clips and turning the left
and right tie rod turnbuckles by the same amount (in
opposite directions).
2.After making the adjustments, use a turning radius gauge to
confirm that the steering wheel turning angle is within thestandard value range. (Refer to GROUP 37A
- Service
Adjustment Procedures.)Standard value:
Inner wheel

Caster3”55’ IL 30’
Install the special tool by tightening it to the same torque as
that applied to the drive shaft nut.
a
To adjust camber, turn the strut lower mounting bolt (upper).
One graduation is equivalent to about 20’ in camber. Caster hasbeen factory-adjusted to the standard value and requires no
adjustment.
Caution
1.One camber graduation changes toe by about 0.5 mm
(.02 in.). Be sure to adjust toe after camber has been
adjusted.
2.The difference in camber between right and left shouldbe within
O”30’.
