A bearing liner comprises an elongated resilient non-metallic unitary structure having a plurality of generally planar sides for placement between a steering sleeve and correspondingly planar-sided steering shaft. The liner is adapted to receive the steering shaft, and in a preferred form comprises four sides having a square cross-section. Each juxtaposed side is joined together by a flexible web which has a cross-section substantially thinner than the average cross-sections of the sides. Each of the sides includes two arcuate, axially extending integral spring channels which define its edges and which are designed to accommodate torsional lost motion between the steering shaft and sleeve members. In a preferred form, the liner is formed of an injection molded composition of nylon having carbon fibers and polytetraflouroethylene, the carbon fiber imparting strength to the composition, the polytetrafluoroethylene supplying lubricity.
