Abstract
A lower bearing air strut which moves the point of steering rotation of a dirigible road wheel to the bottom of the reservoir of the strut. This provides improved support between the road wheel assembly and the air strut and allows the air spring to be leak tested prior to vehicle assembly. The upper mount is fixed to the mounting tower by a retainer ring so it does not rotate and provides improved sealing of the upper extremity of the air spring.
