Abstract
A shaft assembly includes a first shaft. The first shaft has a first annular crest and a second annular crest. The first annular crest and the second annular crest are separated by an inclined surface. The second annular crest includes an axially extending surface attached to an end of the inclined surface. A boot is secured to the shaft. The boot includes a channel and a diaphragm portion disposed adjacent an end of the channel. The channel includes an inlet portion, a partially helical portion, and an outlet portion formed in an inner surface of the boot. The diaphragm portion is provided over the inclined surface and includes a lip which contacts the second annular crest.
