SHAFT
ic propeller shaft, between the transmission and the rear axle, is a
' steel shaft, 2) £ inches in diameter in the center, tapering to its
, at each end, turning in a torque tube which completely seals the ensembly.

The rear end of the propeller shaft is rigidly connected to the pinion shaft
of the rear axle by asplined sleeve. The front end of the propeller shaft is
connected to the transmission shaft through a universal joint which is immediately
behind the transmission case and is lubricated by the transmission
lubricant.

A torque tube surrounds the propeller shaft. The rear end of this tube
is bolted to the differential carrier and the front end is pivoted in a ball-andsocket
joint at the rear of the transmission. This tube absorbs the torque
reactions that accompany acceleration and application of the brakes.

Strength and rigidity, with u resultant extremely wide margin of safety
and very long life, are the bases upon which Cadillac engineers have designed
the sturdier frame of the New Cadillac.
The side bars have a long, deep channel section through the center, where
the stress is most severe, and wide top flange. The front sections of the side
frame members are reinforced by steel plates. There is a gradual reduction in
the section toward each end with "kick-ups" over both front, and rear axles.
