RTW 64ASF000101
Torque is transmitted from the transmission to the
axle through propeller shaft and universal joint
assembles. All propeller shafts are the balanced
tubular type. A splined slip joint is provided in some
drivelines.
• Since the propeller shaft is total balanced carefully,
welding or any other modification are not permitted.
•
Alignment marks should be applied to each
propeller shaft before removal.
• Be sure vehicle is stopped, engine is not running,
brake is secured and vehicle is secured to prevent
injury.
• Be careful not to grip the propeller shaft tube too
tightly in the bise as this will be cause deformation.

Phasing
The propeller shaft is designer and built with the yoke lugs
(ears) in line with each other. This design produces the
smoothest running shaft possible, called phasing. Vibration can
be caused by an out-of-phase propeller shaft. The propeller
shaft down each time the universal joint goes around. This
vibration would be the same as a person snapping rope and
watching the “wave” reaction flow to the end. A propeller shaft
working in phase would be similar to two persons snapping a
rope at the same time, and watching the “waves” meet and
cancel each other out. In comparison, this would be the same
as the universal joints on a propeller shaft. A total cancellation
of vibration produces a smooth flow of power in the driveline. It
is very important to apply a reference mark to the propeller
shaft before removal, to assure installation alignment.

Universal Joint
A universal joint consists of two Y-shaped yokes (2) connected
by a crossmember called a spider (1).
The spider is shaped like a cross. Universal joints are designed
to handle the effects of various loadings and front or rear axle
windup during acceleration. W ithin the designed angle
variations, the universal joint will operate efficiently and safely.
W hen the design angle is changed or exceeded the
operational life of the joint may decrease.
The bearings used in universal joints are of the needle roller
type. The needle rollers are held in place on the trunnions by
round bearing cups. The bearing cups are held inside the
yokes by snap rings.
