Abstract: Disclosed is a method and device for determining potential damage of an endless track of a tracked vehicle. Said vehicle comprises at least one track assembly comprising a drive wheel member, a tension wheel member, a set of road wheels and said endless track disposed around said wheels. Said endless track is rotated by means of said drive wheel member during drive. The method comprises the steps of: receiving, from at least one sensor, measurement information associated with vibrations of said endless track; based on the information received from said at least one sensor, determining if there is a natural frequency of said endless track and if so determining the natural frequency of said endless track; and, based on the determination associated with natural frequency, determining whether there is a potential damage to the endless track.
