ing wheel hub by pressing downward
and turning the cap to the left. Make
sure the alignment mark on the hub
of the steering wheel is lined up with
the mark on the end of the steering
shaft. The mark on the end of the
shaft indicates the high-point of the
steering gear. With the front wheels
straight-ahead, the alignment marks
should be vertical and the steering
wheel spokes should be in their
normal position. If repositioning is
required, refer to STEERING
WHEEL SPOKE POSITION ad-
justment procedure which follows.
3. To adjust toe-in, loosen the two
clamps on each spindle connecting
rod sleeve. Lengthen or shorten both
spindle connecting . rods an equal
amount to obtain the correct toe-in.
Lengthening both rods increases toe-
in. Shortening both rods decreases
toe-in (Fig. 3).

clamp bolts to specification. To pre·
vent interference, both bolts should
be in a vertical position on the rear
side of the sleeve and the clamps
should not project beyond the
ends of the sleeve.
STEERING WHEEL SPOKE
POSITION
When the steering gear is on the
high-point, the front wheels should
be in the straight-ahead position and
the steering wheel spokes should be
in their normal position. The marks
on the end of the steering shaft and
on the hub of the steering wheel
should also be lined up and in a
vertical position. If necessary, the
spokes can be repositioned without
changing the toe-in setting (Fig.
4) .

CLEANING AND INSPECTION
FRONT END GENERAL
INSPECTION
Whenever possible, front wheel
alignment checks should be per-
formed on stationary wheel aligning
equipment. In, the absence of such
downward the same number of turns
to move the steering wheel spokes to
their normal position. If the wheel is
turned clockwise from its normal
position, turn both sleeves upward
(viewed from the rear). If the wheel
is turned counterclockwise, turn both
sleeves downward (viewed from the
rear).
3. Tighten the sleeve clamp bolts
to specified torque.
TURNING ANGLE
The angular relationship of one
front wheel to the other must change
as the vehicle makes a turn. The
turning angle o( an outside wheel
should be 17o 42' when the inside
wheel is turned 20°. If the turning
angle does not check to these sped-
cations, crosswear of tires will result.
Bent parts are generally the cause
of an incorrect turning angle.
THEORETICAL KING PIN
INCLINATION
Theoretical king pin inclination is
the tilt of the top of the spindle to-
ward the centerline of the car. King
pin inclination is merely a theoretical
value as the desired inclination is
built into a car at the time of manu-
facture and cannot be adjusted. Un-
less related parts are bent, the angle
will be 7o when the camber angle
is positive 3 14

WHEEL INSPECTION
Wheel hub nuts should be in-
spected and tightened to specifica-
tion during pre-delivery inspection.
Loose wheel hub nuts may cause
shimmy and vibration. Elongated
stud holes in the wheels may also re-
sult from loose hub nuts.
Keep the wheels and hubs clean.
Stones wedged between the wheel
and drum, and lumps of mud or
grease can unbalance a wheel and
tire.
Check for damage that would
affect the runout of the wheels.
Wobble or shimmy caused by a
damaged wheel will eventually
damage the wheel bearings. Inspect
the wheel rims for dents that could
permit air to leak from the tires.
