Method for mounting a cylindrical bearing having a closed end wall around a trunnion of a cross member of a universal joint by fitting the bearing in a bore of the corresponding yoke under such conditions that the end wall of the bearing affords an elastically yieldable support, optionally through intermediate means, for the end face of the trunnion. The method comprises giving to the end face of the trunnion and to the parts conjugate therewith, namely the end wall of the bearing and/or the intermediate means, such an arrangement that, in a first stage of said fitting, when the parts conjugate with the end face merely come in contact with the latter and possibly in mutual contact, a first axial distance between the open end of the bearing and the end face is distinctly less than a second axial distance which must be finally obtained between the open end of the bearing and the end face. Thereafter, the end wall of the bearing and/or the intermediate means are plastically deformed, in a final stage of said fitting, so as to eliminate the differencebetween said two axial distances and thereby achieve said elastically yieldable support by elastic return consecutive to the plastic deformation.
