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.

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 cente
r
marks at rear end.
The toe-in can be calculated with the following formula.
Toe-in = B - A
Toe-in mm (in)

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.

Adjustment
Adjust the trim height by means of the adjusting bolt on the
height control arms.
1. Check and adjust the tire inflation pressures.
2. Park the vehicle on level ground and move the front of the vehicle up and down several times to settle the suspension.
