Abstract: An illustrative embodiment includes a propshaft system including a first constant velocity joint generally defining a first axis and having an inner first race, an outer first race, and a first grease cover mated to the outer first race. The propshaft system also includes a first flange having a first flange mating surface and a first flange contour surface. The propshaft system also includes a second constant velocity joint generally defining a second axis and having an inner second race, an outer second race, and a second grease cover mated to the outer second race. The second grease cover is defined, at least in part, by a second grease cover flange surface and a second grease cover contour surface. The propshaft system additionally includes a propshaft portion extending at least partially between the first connection apparatus and the second connection apparatus.

Abstract: A propeller shaft for use in a motor vehicle having an in vehicle installation error proofing method includes a fixed constant velocity joint on one end of the shaft, a plunging constant velocity joint on the opposite end of the shaft. The plunging constant velocity joint having a mechanical stop to prevent backwards installation of the shaft in the vehicle driveline.

Abstract: An improved constant velocity joint grease cover and flange assembly and method of making the same. The constant joint has a mating surface with a first anti-slip portion. The flange has a mating surface with a second anti-slip portion, the grease cover has a first mating surface with a third anti-slip portion adapted to receive and mate with the first anti-slip portion of the constant velocity joint, and a second mating surface with a fourth anti-slip portion adapted to receive and mate with the second anti-slip portion of the flange. The respective anti-slip portions functions to reduce shearing forces on connecting bolts of the assembly caused by applied torque.
