3A-8 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.

Caster and camber adjustment

The camber angle and caster angle can be adjusted by means of the camber shims and caster shims installed in
position between the chassis frame and fulcrum pins.

Notes:
1. Adjusting cam is at initial position (the hole & projection

are upward as shown in a illustration) before a shim
adjustment.

2. Difference of caster shim front/rear thickness should be

3.6mm(0.142in) or less.
Overall thickness of caster shim and camber shim
should be 10.8mm(0.426in) or less.

3. Make a combination in a such a way that the number of

shims is at a minimum.
