COMMON ADJUSTMENTS AND REPAIRS
After front wheel
alignment
factors
have been checked, make the neces-
sary adjustments.
Do
not
attempt
to
adjust
the front
wheel
alignment
by
bending
the
suspension or steerln1

CASTER AND CAMIIR
ADJUSTMENTS
Precaution should be taken when
checking the front
.
wheel alignment.
When carrying out the check of
caster angle, it is possible that the
lower strut
arm·
bushes
may not
always be under equal
compression
and therefore, will tend to
bias the
strut rod in a
forward
or rearward
position, thus
afFecting
the steering
caster angle when the wheels are
turned through their
checking
posi-
tions.
It
is
essential
that
whenever
the
steering caster angle is
checked, that
the
distance
from
the strut brac-
ket to each of the
washers
is the
same. When
checking the
caster
angle it
is
mandatory
that
the strut
rubbers
are centralised before taking

Caster is
controlled
by the front
suspension
strut (Fig.
8).
To obtain
positive caster,
loosen the strut
rear nut
and tighten
the strut front
nut
against
the
bushing.
To obtain
negative caster,
loosen the strut
front nut
and tighten the
strut rear
nut
against
the
bushing.
Note:
Always
loosen the
appropriate
nut fir.st before attempting
to
adjust
Caster,
to
avoid
collapsing the tube between the
washers
or
damaging
·
the
serrated
nut.
Camber
is
controlled
by
the
ec-
centric cam located at the
lower arm
attachment
to the side rail (Fig. 8).
To
adjust
the camber, loosen
the
ec-
centric
bolt
nut and
spread
the re-
taining body bracket
sufficiently
to.
allow

movement
of the arm
assembly

before attempting
to turn the eccentric adjuster.
Rotate
the bolt
and
eccentric clockwise from
the high position to increase camber
or
counterclockwise to decrease
camber.
After the caster and camber has
been
adjusted
to specification, torque
the lower arm eccentric bolt nut and
the strut front nut to specification.
TOE-IN AND STEERING WHEEL
ALIGNMENT ADJUSTMENTS
Check the steering wheel spoke po-
sition when the front
wheels are
in
the
straiaht-ahead
position.
If
the
spokes
are not in
their normal posi-
tion, they
can be
properly adjusted
while toe-in
is
being adjusted.
1. Loosen the two clamp bolts on
each
spindle
connecting rod sleeve
(Fig. 9).
2.
Adjust
toe-in.
If the steering
wheel spokes are in their normal
position,
lengthen or shorten both
rods equally
to
obtain correct toe-in
(Fig.
1
0). If the steering wheel
spokes are not in their normal
posi-
tion, make the necessary rod
adjust-
