Constant Velocity Universal Joints
The one-piece propeller shaft requires only two CV
universal joints, mounted at each end of the shaft.
On 75 models, three universal joints and a two-
piece propeller shaft are used. These CV joints,
permanently lubricated, help transfer power to the
rear axle smoothly and quietly, with little or no
vibration.
They are constructed and installed with
the advantage that each offsets any vibration-setting
tendencies of the other.

The Cadillac wheel has a second safety bead retainer
for added assurance of the tire remaining on the
rim in the event of sudden deflation. The tread
design,
extending onto the shoulders, means
road-
clutching action, even in turns. Long-wearing, tough
rubber compounds assure excellent durability under
normal driving conditions. A 9.00 x 15 tubeless
blackwall is standard on all models with the excep-
tion that, on the Seventy-Five models, an 8.20 x 15
tubeiess blackwall is provided.

The energy-absorbing steering column that is
standard on ail models has improved energy ab-
sorption capabilities for 1909. Under the instrument
panel,
the collapsible Jacket is constructed of soft,
durable plastic "pre-folded" into sections to enable
it to telescope up to 8%." upon severe impact. Im-
bedded in the plastic are rows of ball bearings. Upon

impact, the jacket "rolls" into the collapsible or tele-
scopic position. When a force is applied to the front
or gear end of the column, the column collapses up-
ward.
When a force is applied to the rear or steering
wheel end of the column, the column collapses
downward.
In addition, the steering wheel is padded
for increased driver protection.
