An assemblage far mounting a caster wheel (3) on a depending stationary post (10) on a wheeled load carrier comprises a body element (20) having a cylindrical chamber (20a) concentrically surrounding the support post (10). The body element has a bracket (20b) for mounting a caster wheel for rotation about a horizontal axis. A vertical stack of washers (21, 22) surround the support post and alternate ones of such washers are secured to the support post and rotatable within the cylindrical chamber while the remainder of such washers arc co-rotatable with the body element about the axis of the support post. The cylindrical chamber is filled with a lubricating fluid to a sufficient depth to cover all abutting surfaces of said washers, thereby providing viscous fluid sharing resistance to shimmying movement of the raster wheel relative to the support post.
