Drive/Propeller Shaft: Description and Operation
Propeller Shaft Description and Operation
The Propeller Shaft is a tube with universal joints at both ends which do not require periodic maintenance, that transmit power from the transfer case
or transmission output shaft to the differential.
Front Propeller Shaft Description
The front propeller shaft transmits rotating force from the transfer case to the front differential when the transfer case is engaged. The front propeller
shaft connects to the transfer case using a splined slip joint.
One Piece Propeller Shaft Description
A one piece propeller shaft uses a splined slip joint to connect the driveline to the transmission or transfer case.
Universal Joint Description
The universal joint is connected to the propeller shaft. The universal consist of 4 caps with needle bearings and grease seals mounted on the trunnions
of a cross or spider. These bearings and caps are greased at the factory and no periodic maintenance is required. There are 2 universal joints used in a
one piece propeller shaft. The bearings and caps are pressed into the yokes and held in place with snap rings, except for 2 bearings on some models
which are strapped onto the pinion flange of the differential. Universal joints are designed to handle the effects of various loads and rear axle windup
conditions during acceleration and braking. The universal joint operates efficiently and safely within the designed angle variations. When the design
angles are exceeded, the operational life of the joint decreases.
