In a shaker mechanism for wheeled vehicles, wherein each vehicle has a plural number of axles, each axle including a rotary hub and a plural number of threaded studs centered in a ring pattern around the axle axis; said shaker mechanism comprising a plural number of fixtures, one for each axle; and a powered actuator supportably connected to each fixture for imparting vertical oscillatory forces thereto: the improvement wherein each fixture comprises an annular housing; an annular axle-support element located within each housing for universal rotary motion around a point on the axle axis; and an annular adapter plate removably attached to each axle-support element; each adapter plate having a number of circumferentially-spaced openings therethrough arranged in the same ring pattern as the aforementioned studs, whereby each said adapter plate can be fitted onto an axle hub with the studs extending through the adapter plate openings; and nuts threaded onto the studs to rigidly secure the adapter plate to the hub; the adapter plates being sufficiently sized so that adapter plates having different numbers of stud openings therethrough can be removably attached to a given axle-support element, thereby achieving a significant commonality of fixture components while continuing to use existing fixtures with a range of different wheeled vehicles.
