An apparatus and method for determining when a component of a work vehicle experiences vibration above a predetermined threshold, and responding to the vibration so that the vibration is reduced below the predetermined threshold. The apparatus, which is in a work vehicle that includes a chassis, an operator's cab and an active cab suspension system, includes a sensor that is configured to sense a quantity representative of the vibration experienced by the component of the work vehicle and to develop a first signal indicative of that quantity. The apparatus also includes a signal processor that is coupled to the sensor and is configured to develop, in response to the first signal, a second signal indicative of whether the vibration experienced by the component is above the predetermined threshold. The apparatus further includes a device that is coupled to the signal processor and, in response to the second signal, is either configured to provide an indication or configured to take an action to reduce the vibration below the predetermined threshold when the vibration is above the predetermined threshold.
