GENERAL
Jeep vehicles use tubular propeller shafts to transmit
engine torque from the transfer case to the front and
rear axles. Universal joints connect each shaft to the
transfer case and axle yokes. A splined slip yoke is used
at one end of each propeller shaft to compensate for
variations in shaft length caused by suspension spring
movement.
Because of the various driveline combinations avail-
able on Jeep vehicles, several different propeller shaft
and universal joint designs are required.
yoke with a ball and trunnion universal joint and to the
axle yoke by a single cardan universal joint (fig. 2E-4).
The ball and trunnion joint is a dual-purpose unit serv-
ing as both slip yoke and universal joint.
The rear propeller shaft on CJ models with manual or
automatic transmission is similar to the front shaft in
appearance and construction. Single cardan universal
joints connect the shaft to both the axle and transfer
case yokes and the slip yoke is located at the transfer
case end of the shaft.
Propeller Shaft Application
The front propeller shaft on CJ-7, Cherokee, Wagon-
eer, and Truck models with automatic transmission is
connected to the axle yoke with a single cardan universal
joint and to the transfer case yoke with a double cardan
universal joint (fig. 2E-1).
The front propeller shaft on CJ models with manual
transmission is connected to both the axle and transfer
case yokes with single cardan universal joints. A slip
yoke is used at the axle end of the shaft (fig. 2E-2).
The rear propeller shaft on Cherokee and Wagoneer
models with automatic transmission and Truck models
with manual or automatic transmission is connected to
both the axle and transfer case yokes with single cardan
universal joints. A slip yoke is used at the transfer case
