4. STEERING ANGLE
• Inspection
1) Place the vehicle on a turning radius gauge.

ing wheel fully to the right and left. With the steering
wheel held at each fully turned position, measure
both the inner and outer wheel steering angle.
Steering angle:
Turbo and OUT-
Model
34.5 °± °± °± °± 1.5 ° ° ° °
Inner wheel
30.3 °± °± °± °± 1.5 ° ° ° °
Outer wheel
• Adjustment

5. FRONT WHEEL TOE-IN
• Inspection
Toe-in:
0 ± ± ± ± 3 mm (0 ± ± ± ± 0.12 in)
1) Set the toe-in gauge to rear sides of right and left
front tires at height corresponding to center of spin-
dle.
2) Mark each right and left tires at height corre-
sponding to center of spindle and measure the dis-
tance "A" between marks.
3) Move the vehicle forward to rotate wheels 180°.
NOTE:

4) Measure the distance "B" between right and left
marks. Toe-in can then be obtained by the follow-
ing equation:
A − − − − B = Toe-in
B
• Adjustment
1) Make sure that the right and left steering angles
are within specified value.
2) Loosen the right and left side steering tie-rods
lock nuts.
3) Turn the right and left tie rods equal amounts un-
til the toe-in is at the specification.
Both the right and left tie-rods are right-hand
threaded. To increase toe-in, turn both tie-rods
clockwise equal amounts (as viewed from inside of
the vehicle).
