Drive/Propeller Shaft: Description and Operation
Front Propeller Shaft
Propeller shafts transmit torque from the transmission to the rear axle. The number of propeller shafts varies with the vehicle wheel base combination
of transmission, transfer case, and rear axle equipment.
One Piece Propeller Shaft
For a 1 piece propeller shaft, a splined slip joint connects the driveline to the transmission or the transfer case.
Two Piece Propeller Shaft
For 2 piece propeller shafts, a fixed yoke or slip yoke connects the driveline to the transmission or the transfer case.
Propeller shafts have universal joints at each end in order to accommodate angle variations between the transmission and the rear axle, and the rear
axle position caused by suspension motion. All propeller shafts are the balanced tubular type.
Vehicles with 2 propeller shafts use a center bearing. The center bearing is at the rear of the front propeller shaft. The slip joint is at the forward end of
the rear propeller shaft.
