both front wheel caster angles should
not exceed ?ho. However, a differ-
ence of not more than
?A0
is pre-
ferred.
CAMBER
Check the camber angle at each
front wheel.
Camber is the amount the front
wheels are tilted at the top. If a
wheel tilts outward, camber is posi-
tive. If a wheel tilts inward, camber
is negative. The correct camber
angle, or outward (positive) tilt, is
+
1
%
"
'
%
".
The maximum differ-
ence between both front wheel cam-
ber angles should not exceed
'/zO.
However, a difference of not more
than
?A
is preferred.
TOE-IN
Check the toe-in with the front
wheels in the straight-ahead position.
Run the engine so that the power
steering control valve will be in
the
center
(neutral)
position.
Measure the distance between the
extreme front and also between the
extreme rear of both front wheels.
The difference between these two
distances is the toe-in.
Correct toe-in, or inward pointing
of both front wheels at the front, is
?A
-540
inch.
Front Wheel Turning Angle
Six-cylinder
-
The turning angle
of an outside wheel should be 20°?4'
with P/S and 19" with manual steer-
ing when the inside wheel is turned
20".

The turning angle
of an outside wheel should be 19"
when the inside wheel is turned 20".
After front wheel alignment fac-
tors have been checked, make the
necessary adjustments. Do not at-
tempt to adjust the front wheel
alignment by bending the suspen-
sion or steering parts.
CASTER A N D CAMBER
ADJUSTMENTS
Caster and camber can be adjusted
by removing or installing shims be-
tween the inner shaft of the front
suspension upper arm and the under-
body (Fig. 4).
Both caster and camber adjust-
ments can be made at the same time
by loosening the nuts on the two
bolts that fasten the inner shaft to
the underbody. After the required
shims have been removed or in-
stalled, torque the nuts to specifica-
tion. Caster and camber adjusting
shims are available in %-inch and
'/s
-inch thickness.
The
1/32
inch shims should be
placed against the fender housing
sheet metal or between the
inch
shims.
CASTER
To adjust caster, remove or install
shims at either the front bolt or the
rear bolt (Fig. 4).
The removal of shims at the front
bolt or the installation of shims at
the rear bolt will cause the upper
ball joint to move forward. The re-
moval of shims at the rear bolt or
the installation of shims at the front
bolt will cause the ball joint to move
rearward. A %-inch change of shim
thickness at either bolt will change
the caster angle approximately
? h
".

stack thickness at the two bolts
should not exceed
]/lo
inch (Fig. 4).
CAMBER
To adjust camber, remove or in-
stall equal shim thicknesses at both
bolts (Fig. 4).
The removal of equal shims at
both bolts will move the upper ball
joint inward. The installation of
equal shims at both bolts will move
the ball joint outward. A lAo-inch
change of shim thickness at both
bolts will change the camber angle
%". The total shim stack thickness
at each bolt should not exceed KO-
inch (Fig. 4 ) .
TOE-IN AND STEERING WHEEL
ALIGNMENT ADJUSTMENTS
Check the steering wheel spoke
position when the front wheels are in
the straight-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. 5).
2. Adjust toe-in. If the steering
wheel spokes are in their normal po-
sition, lengthen or shorten both rods
