Drive the car at about 30
mile/hr
and
then
take
vour
hands
ofÍ the
steering
wheel. The
car should maintain
a straight course. lÍ the road is crowned, it
may cause
rhe car to wander towards the low side of
the
road
and.
thereÍore, it may be necessary to
make
this
test straddled
over the centre
line.
Uneven
front
end angles will cause
the car to
wander
to one side.

30
mile/hr to check whether
any
shocl<s
are being trans-
mitted
back
to the steering

then release the
steering

assistance
from the
driver.

il indicates
binding
in the linkage, insufÍicient caster
or
insufficient
steering
axis inclination.
To
check
for misalignment,
inspect the front
tyres
for
uneven tread
wear.
