A suspension system for a heavy vehicle, the system comprising a control circuitry configured to compare signals on current vertical position obtained from left and right level sensors and determine whether a current difference in vertical position between left and right leaf springs is greater than first threshold value; if determined difference is greater than first threshold value: determine, based on timing information related to signals provided by inertial measurement unit and left and right level sensors, whether the determined difference in vertical position between left and right leaf springs is related in time with signal from inertial measurement unit indicating that the angular velocity of wheel axle is greater than a second threshold; and, if determined difference in vertical position not related in time with signal indicating angular velocity of wheel axle is greater than second threshold, generate alarm signal indicative of detected or possibly detected leaf spring failure.
