ABSTRACT:
A plate, for use in adjusting the rear wheels of a four wheel vehicle incorporating all wheel steering has an elongate sheet-form bearing cage, which includes a plurality of apertures. Ball bearings or other rolling elements are located in the apertures, and a top sheet member is located on top of the ball bearings. In use, the ball bearings are supported on a horizontal planar surface, for example a support platform of a hydraulic lift or a separate base sheet member. The configuration of the cage and the bearings is such that the top sheet member is capable of limited lateral and rotational movement in a horizontal plane, to permit full adjustment of rear wheels of a vehicle having a steering capacity.
