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

To adjust the toe-in angle, loosen the lock nut on the outer
track rod and turn the outer track rod with the same degree as
right and left.

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 f r ont 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 4×2
model (except TFR25) only ).
