Drive/Propeller Shaft: Description and Operation
Propeller Shaft Description
Most universal joints require no maintenance. They are lubricated for life and can not be lubricated on the vehicle.
If a universal joint becomes noisy or worn, it must be replaced.
The propeller shaft is a balanced unit. Handle it carefully so that balance can be maintained. A viscous coupling is used for the coupling system which
distributes an optimum driving force to the front and rear wheels according to the driving conditions. It is located at the center of the propeller shaft.
