A universal joint between an upper steering shaft and a lower steering shaft in a tilt-adjustable motor vehicle steering column includes a pair of bifurcated yokes formed to near-net-shape integrally with the upper and lower shafts, a plastic jacket molded in-situ on each of the bifurcated yokes, and a plastic centering sphere. Each of the plastic jackets has a pair of exposed, frusto-conical bearing surfaces molded thereon which slidably engage corresponding frusto-conical side walls of cross grooves in the plastic centering sphere.
