Creep groan noise occurs in a just moving vehicle by the simultaneous application of torque to the wheel and the gradual release of brake pressure in-vehicle. It is the low frequency noise giving the driver a very uncomfortable feeling. Recently, the field claims regarding the creep groan noise are increasing. So far, creep groan noise has been improved by means of chassis modification the transfer system. But the research for vehicle body the response system has not been done yet. In this paper, the effect between vibration characteristics of the vehicle body and creep groan noise was analyzed. Then analysis method for vehicle body effect regarding creep groan noise is presented
