A universal joint includes a first joint yoke and a second joint yoke having respective base portions. Each of the joint yokes has two yoke arms that are attached on the respective base portions. Each of the yoke arms ends in a free end and has an inner face facing toward the longitudinal axis and an outer face facing away from the inner face. Each of the yoke arms has a bearing bore extending between the outer face and the inner face. The inner face of each of the yoke arms has a first recess that is open toward the free end and that ends in the corresponding bearing bore. A journal cross assembly includes a journal cross having four circular cylindrical trunnions arranged at right angles toward each other, each trunnion supporting a bearing bushing having a cylindrical envelope face and a cylindrical bore. The bearing bushings are supported on the trunnions by rolling members. The envelope face, in the area of the first recess, has a first support-free portion and, diametrically to the first support-free portion, a second support-free portion that is provided between the bearing bushing and the corresponding bearing bore.
