Cadillac Drive Line
The use of a one-piece propeller shaft
(two-piece with center support on 75
series), precisely aligned with the rear
axle pinion gear through machined
mountings, transmits power from the
transmission to the rear axle with
utmost quietness and resistance to
vibration.
Constant Velocity Joints
Further contributing to smooth, quiet
transmission of power to the driving
wheels is the use of CV (constant
velocity) joints at the ends of each
propeller shaft. In effect, the CV joint
is like combining two U-joints with the
advantage that each serves to offset
any vibration-setting tendencies of the
other.
Rear Axle
The rear axle housing is of exception-
ally strong, rigid construction with a
minimum number of sections and
welds. Rear axle pinion seal has a two-
lip design, outer lip sealing out dirt,
inner lip sealing in lubricant. Bearings
are prestressed for long lasting smooth-
ness and durability.
Tires and Wheels
Cadillac wheels have safety rims which
tend to hold the bead of the tire to the
rim even in event of sudden deflation.
Tires have tread design extending onto
shoulders for smooth cornering. Im-
provements in tread design and com-
pounds, cord material and bonding
assure even greater durability for 1967.
