Drive/Propeller Shaft: Description and Operation
DESCRIPTION
A propeller shaft (Fig. 1) connects the transmission/transfer case to the axle differential. This is the link through which the engine power is transmitted
to the axle.
The propeller shaft is designed and built with the yoke lugs in line with each other which is called zero phasing. This design produces the smoothest
running condition, an out-of-phase shaft can cause a vibration.
Tubular propeller shafts are balanced by the manufacturer with weights spot welded to the tube.
Use the exact replacement parts when installing the propeller shafts. The use of the correct replacement parts helps to ensure safe operation. All
fasteners must be torqued to the specified values for safe operation.
Also make alignment reference marks (Fig. 2) on the propeller shaft yoke and axle, or transmission, yoke prior to servicing. This helps to eliminate
possible vibration.
