Zusammenfassung:	A diagnostic driveline vibration analyzing tool (10) for measuring and characterizing the torsional vibrations in a vehicle driveline. An electronic control unit (22) and sensor (12) cooperate to measure speed fluctuations occurring between the passing of adjacent teeth of a rotating gear. These time measurements are the basis for displacement, velocity and acceleration calculations which, combined with driveshaft rotational order information, can be used to pinpoint the source of excessive driveline torsional vibrations.
