A universal joint is disclosed which is made primarily of plastic. A center cube of the joint has two pairs of opposed rod ends. The arms of bifurcate members may be molded directly about the rod ends, or on a bearing mounted about the rod ends. The bifurcate members may be all plastic or plastic-covered steel. The center cube and rod ends may be molded as one integral plastic unit or, if desired, the rods may be made of steel with the center cube made of plastic and molded about the rods.
