The mechanisms of destruction of compensation characteristics of rotational speed fluctuation of a pair of Hooke's joints on a propeller shaft is clarified by experimental and computational analyses. The destruction is caused by the backlash of the spline joint connecting transmission output shaft and propeller shaft. Because of the backlash, fluctuation cannot be compensated and grows up into torsional vibration in the whole drive train. This vibration also includes the fluctuation of the drive pinion of the differential unit, which is closely related to the rattling noise emitted from the unit
