Abstract
A vehicle noise, vibration and harshness analysis tool according to the present invention comprises at least one sensor, each sensing a vibration or noise and generating a signal at a frequency related to the vibration or noise. A communication link with a vehicle is included to transmit data regarding the vehicle. A microprocessor system receives the signals generated by said at least one sensor and receives the vehicle data over said communication link. The microprocessor system conducts an analysis of the received sensor signals and vehicle data and identifies a vehicle component that is likely causing a vibration or noise. The microprocessor system also identifies the possible problems with the identified vehicle component. A user interface is also included with a display. The microprocessor system causes the display to list the likely vehicle components causing the vibration or noise and the possible problems with the components. The list of likely components and causes helps the technician quickly isolate and remedy the cause of the vibration or noise. The invention also discloses methods for balancing a driveshaft using analyzers according to the invention.
