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.
