When camber is increased, pivot pin inclination is de-
creased. Decreasing camber increases pivot pin inclina-
tion.
TOE -IN:
Toe-in is the drawing together of the front wheels at the
front. This is accomplished by making adjustments at the
tie rod ends which establish a shorter distance between
the wheels at the front than at the rear. Camber tends to
cause the wheels to separate or spread at the front, and
sufficient toe-in is necessary to compensate for this ten-
dency and make the wheels run straight. Accurate toe-in
is of great importance in obtaining maximum tire life.
Toe-in must be within the definite limits of 0" to 1/16"
MEASURED AT THE WHEEL RIM.
TOE -OUT:
Toe-out on turns is controlled by the movement and
angularity of the steering arms. Toe-out is checked by
turning the wheels to the right or left as far as possible.
When the front wheels are turned to the right or left, they
separate slightly at the front. This separation increases as
the turn is increased from the straight ahead position. The
wheel making the inside turn turns at a greater angle than
does the outside wheel; thus toe-out is very necessary to
keep the two front wheels turning together properly
around curves and corners. The amount of toe-out in-
creases due to the change in angle between the tie rods
and steering arms.
TOE-OUT MUST ALWAYS BE CHECKED WITH
THE WEIGHT OF THE CAR ON THE WHEELS.
Front wheels must rest on full floating turntables, and the
turning angles should read as follows:
Left Turn
Left Wheel 30°
Right Turn
Right Wheel 30°
The difference between the left and right wheel angle
must not vary more than 30° minutes, plus, or minus,
from specifications.
RIDING HEIGHT AND COIL
SPRING SAG
When the car does not seem to be level, and a check of the
coil spring height is desired, place the car so that the front
end is level crosswise and then rock the car sidewise
several times and allow the car to settle. This will remove
any binding that might cause a dimensional difference.
Measure the distance from the top of the lower arm rubber
Right Wheel 25° bomber seat to the bottom of the upper rebound bracket,
which should be 4-1/4" on each side, Figure 43.
Left Wheel 25° If the two measurements vary more than 1/2" between
sides, it is advisable to replace one or both coil springs.
The light and heavy coil springs may be identified by the
part number stamped on the top coil of spring.
