In at least some implementations, a differential for a vehicle includes a pinion gear, a pair of side gears and a housing. The side gears are meshed with the pinion gear and the housing defines a cavity in which the pinion gear and side gears are received. The housing also has an opening with an inner end leading to the cavity and an outer end spaced from the inner end. The opening is adapted to receive a shaft therethrough for coupling of the shaft to one of the side gears and the opening is defined at least in part by a journal surface. The journal surface is concave with respect to the shaft and provides a converging portion from the inner end to a central portion between the inner end and outer end and a diverging portion from the central portion to the outer end.

A boot assembly for an articulating joint is provided, including an inner layer and an outermost layer. The inner layer is constructed from a first material and the outermost layer is constructed from a second material that is different from the first material. The outermost layer at least partially covers the inner layer, and the second material includes a self-repairing polymer.
