Drive/Propeller Shaft: Description and Operation
The basic function of a propeller shaft is to transmit power from one point to another. The shaft is designed to send torque through an angle from the
transmission to the axle.
The propeller shaft must operate through constantly changing relative angles between the transmission and axle. It must also be capable of changing
length while transmitting torque. The axle rides suspended by springs in a floating motion. This means the propeller shaft must be able to contract,
expand and change operating angles. This is accomplished through universal joints. Universal joints permit the propeller shaft to operate at different
angles. The slip yokes permit contraction or expansion.
Tubular propeller shafts are balanced by the manufacturer with weights spot welded to the tube.
Before undercoating a vehicle, the propeller shaft and the universal joints should be covered. This will prevent the undercoating from causing an
out-of-balance condition and vibration.
CAUTION: Use exact replacement parts for attaching the propeller shafts to ensure safe operation. The specified torque must always be applied when
tightening the fasteners.
