Abstract
A shaft for a vehicle including a first member having an internal spline and defining an inner cavity, a second member having an external spline, and a boot mounted over the vent and adapted to substantially prevent contaminants from entering the inner cavity through the vent. The external spline of the first member and the internal spline of the second member cooperatively allow an axial sliding movement of the second member into the inner cavity of the first member and substantially prevents rotational movement between the first and second members. One of the first and second members defines a vent communicating with the inner cavity. The first and second members and the boot cooperatively form a substantially airtight enclosure.
