The caster angle can be adjusted by varying length of the strut
bar (adjust with lock nut) and shims should not be used for
adjustment.

The caster angle can be adjusted by means of the caster
shims installed in position between the chassis frame and
fulcrum pins.
Note:
Difference of the caster shim front/rear thickness shall be
3.2 mm (0.126 in) or less. Overall thickness of caster shim
and camber shim shall be 10.8 mm (0.426 in) or less.

Measurement of Side Slippage

When inspection and adjustments of toe-in, camber, caster
and kingpin inclination are completed, check for side slippage
using a side slip tester.
Roll the wheels over the side tester as slowly as possible and
take reading on the tester.  If the amount of side slippage is in
excess of 5 mm per 1 m, recheck the wheel alignment.

3A-4 FRONT ALIGNMENT

TOE-IN

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 next formula.
Toe-in = B - A

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 a level ground and move the front of the

vehicle up and down several times to settle the suspension.

3. Loosen the nuts on the front end of the strut bar.  (For 4
