Abstract

A universal joint includes a seal assembly that is positioned between each trunnion and a corresponding cup. The seal assembly includes a resilient seal that engages an inner surface of the cup and an outer surface of the trunnion. A deflector provides a snap fit for attaching the cup to the trunnion. The deflector is formed form a rigid and deformable material that protects the resilient seal from contamination, in addition to retaining the cup to the trunnion.
