Contact noise generated between a striker cap mounted on a strut and a jounce bumper connected to a shock tower is reduced by providing an axial projection on the roof of the striker cap. The projection progressively displaces and compresses the elastomeric jounce bumper material and thereby avoids large compressive impulse forces and associated noise generation.

A sealing washer assembly includes a threaded fastener, a nut and a resilient member attached to the nut and washer or screw and washer. The resilient member, typically a polymer of propylene, ethylene or other suitable material, is oversized with respect to the nut. The assembly is useful for connecting one member to another via an opening in the first member, and particularly, provides a system for sealing the opening against the passage of fluid, such as air.

An automotive suspension strut module has an upper mount assembly which includes a unitary plastic upper mount carrier formed with a through passage which is concentrically disposed about the strut principal axis. The passage is formed with a recessed pocket terminating in an internal annular shoulder, on which is seated a composite strut rod isolator having a metal rod connector cup embedded therein. The rod threaded upper end, which is positioned through a cup bottom wall aperture for threaded attachment by a nut, has its isolator annulus bonded to the connector cup by virtue of the side wall of the connector cup being embedded in the annulus of the rod isolator, whereby the strut rod loads may be tuned independently of the suspension travel loads. An upper end of the plastic carrier is molded with a radially outward flange, defining a circular undersurface seat for an upper end of the suspension helical spring, thereby providing a compact light weight strut upper mount assembly that is readily mounted to the vehicle body structure.
