Abstract
The pivot joint assembly includes a housing with an inner wall that surrounds an inner bore which extends along a central axis. A stud is partially received in the inner bore, projects out of one axial end of the housing and is rotatable relative to the housing about the central axis. A sealing body, which is made of a single piece of a semi-rigid material, is in a static sealing condition with the housing and is in a dynamic sealing condition with the stud. The sealing body includes a portion which extends at an acute angle relative to the central axis to contact the stud such that the portion is deflectable to allow lubricant to escape the inner bore during greasing.
