WHEEL ALIGNMENT
It
i s essential that rear wheel alignment i s checked using equipment which measures
individual wheel alignment. The most reliable and accurate method i s considered to
be the use of para1 lel bars, as used on production.
Two
ban
which are longer than the overall length of the car, and
4
axle stands are
required. The bars should be obtained locally and should be of
'T'
or square section
and be sufficiently rigid to avoid significant bending or sagging between supports.
Set up the two ban on each side o f the car.at wheel centre height as shown i n the
diagram, so that A equals A,
B
equals
B
and
C
equals
C.
Measure the distance from the bar to the
RIM
of the wheel concerned at front and rear
of the centre line o f the wheel.
If
the front dimension
i s
greater than the rear dimension,
the wheel has
TOE-IN. If
the rear dimension is greater than the front dimension, the
wheel has
TOE-OUT.
The difference between the two measurements i s the amount the
wheel has
TOE- IN
or TOE-OUT.
