Vehicle driveline joint including a vent and seal assembly

A multi-piece propeller shaft comprising:

• a first shaft segment and a second shaft segment;
• a constant velocity joint disposed between and operably interconnecting said first and second shaft segments;
• said constant velocity joint including an outer race extending along an axis A from a first outer race end operably connected to said second shaft segment to a second outer race end to define an inner surface bounding an internal cavity;
• a vent and seal assembly disposed inside said outer race in abutting relationship with said inner surface;
• said vent and seal assembly defining a plurality of venting cavities disposed serially along said axis A in fluid communication with one another, with a first one of said plurality of venting cavities disposed in fluid communication with said internal cavity and a last one of said plurality of venting cavities disposed in fluid communication with an environment of said constant velocity joint for venting air from said internal cavity to said environment;
• and
• a one-way valve member disposed in the path of fluid communication between said plurality of venting cavities.
