Abstract

Abstract A strut rod mounting assembly of the type which utilizes a pair of resilient bushings disposed on opposite sides of a vehicle frame member. A terminal end of the strut rod passes through a frame member opening and openings in the bushings with an alignment cup interposed between each bushing and the frame member. Each alignment cup includes a first cylindrical flange closely received in the frame member opening for piloting the cup itself and a second cylindrical flange closely received over an axial portion of the associated bushing outer periphery. This second cylindrical flange acts to pilot the associated bushing and thereby eliminates the need for internal piloting and pivoting means which adds high load forces on the bushing inside diameter, causes bushing pinching and abraiding and reduces the mounting assembly overall life.
