3A-12 FRONT ALIGNMENT

Toe-in Adjustment

Measurement should be taken with the vehicle on a surface
plate.
If a surface plate is not available, toe-in should be checked
with the vehicle parked on a level floor.
1. Set front wheels to straight ahead position.

2. Align the toe-in gauge with center height of each wheel at

front end.

3. Apply center marks to each wheel, then take measurement

of distance A between the center marks on each wheel.

4. Slowly move the vehicle rearward until the center marks

reach the rear end position.

5. Take measurement of distance B between the center

marks at rear end.

The toe-in can be calculated with the following formula.
Toe-in = B - A

To adjust the toe-in angle, loosen the lock nuts (2) on the tie
rod (1) and turn the tie rod. Turn both rods the same amount,
to keep the steering wheel centered.
