1938 Cadillac V16 - GM Heritage Center

In cars using the conventional front axle there is an
inherent tendency toward wander and pulling from side
to side, particularly when braking. This is because the
axle rolls forward under braking load. When striking
a bump the conventional axle never moves in quite the
precise curve to give correct steering geometry. This
causes steering wheel whip.
In the Sixteen geometrical relationship of the various
parts of the steering system is accurately controlled at
all speeds. Each front wheel is directly connected to
the frame by rigid forged forked arms which accurately
control wheel motion. The upper forked arm is shorter
than the lower by a sufficient amount to maintain constant
tread regardless of spring deflection. Constant
tread prevents sidewise scrubbing of the tire upon the
road's surface.
The two steering cross rods are of the same length
and parallel to the lower forked arms which avoids
errors in steering geometry. They are joined and controlled
at the center by a longitudinal drag link. A roller
shaft extends from the drag link through the frame sidebar
and is straddle mounted on the steering gear
housing. The steering gear is of the sturdy worm and
double roller design. Two extremely strong universal
joints which contribute to handling ease are used in
the steering column.
Shock Absorbers
Cadillac's exclusive end-to-end discharge type shock
absorbers with dash pot inertia controls at the rear are
used on the Sixteen. This is the finest and most costly
shock absorber equipment available and provides a
degree of luxurious comfort over any kind of road that
has never been equalled.
