Abstract
A half shaft assembly includes a half shaft having inboard and outboard ends with constant velocity universal joint inner races secured thereto. A universal joint cage and ball assembly encircles each inner race. An outer race encircles each cage and ball assembly. A protective elastomeric convoluted semi-hyperbolic boot is provided. The boot has divergent inboard and outboard ends and a convergent center. The convergent center has an inner diameter sized to fit snugly around the half shaft. The divergent inboard and outboard ends are secured to their respective inboard and outboard constant velocity universal joint outer races by a separate clamp.
