A sensor system includes one or more sensors 116 that sense vibrations of a vehicle 104 and one or more processors 106; 118 that can determine a speed of the vehicle 104 and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle 104) indicate damage to a propulsion system 110 of the vehicle 104. The one or more processors 106; 118 optionally may determine a hunting frequency of a wheel 112 and axle set and/or a lateral acceleration of the wheel 112 and axle set from the vibrations. The one or more processors 106; 118 can determine a conicity of a wheel 112 in the wheel 112 and axle set based on the hunting frequency and/or the lateral acceleration that is determined.
