Abstract: A torsional vibration absorber for a vehicle is provided. The torsional vibration absorber including a front pilot bearing adapted to couple with a vehicle shaft. A spring member is coupled to the front pilot bearing. An inertia ring having an inner surface is operably coupled to the spring member, wherein the front pilot bearing is centrally disposed along the length of the inertia ring. A rear pilot bearing is adapted to couple with the vehicle shaft, the rear pilot bearing having a portion adjacent the inner surface at one end of the inertia ring.

Abstract: An adapter for sealing an outer joint portion of a joint assembly, the adapter includes a main body having an aperture for receiving an outer joint portion, the aperture including an inner sealing surface. The inner sealing surface has a plurality of track portions and a plurality and root portions, where each root portion includes a root midpoint and two track connecting points. The track connecting points connect the root portion to the track portion. The root portion includes a first root radius and an offset root radius, where the first root radius is measured from a first center, and the offset root radius is measured from an offset center. The offset center is located closer to the center axis of the adapter than the first center. Each root portion includes the first root radius at the track connecting point, and gradually transitions to the offset root radius.
