A structure for retaining a bearing cup mounted on a universal joint cross within an opening formed through an arm of an end yoke during use. An external circumferential groove is formed about the outer surface of the bearing cup. An internal circumferential groove is formed about the inner surface of the opening formed through the arm of the end yoke. A recessed area is formed on a surface of the arm of the end yoke adjacent to the opening. The recessed area is of sufficient depth that it extends below the internal groove formed within the opening. Thus, a portion of the internal groove is exposed to the arm surface. To retain the bearing cup within the opening, a snap ring having a central portion and a pair of leg portions is installed such that the leg portions extend into the internal groove formed in the opening. The bearing cup is inserted within the opening until the external groove on the bearing cup is aligned with the internal groove formed in the opening. When this occurs, the leg portions of the snap ring extend into both the external groove formed in the bearing cup and the internal groove formed in the opening. The central portion of the snap ring is maintained within the recessed area formed in the surface of the end yoke arm. As a result, access to the snap ring is maintained for easy removal when disassembly of the bearing cup from the end yoke arm is desired. |
