Abstract
A jounce bumper and dust shield subassembly includes a washer having an annular opening for receiving a piston rod of a damper. A jounce bumper includes an axial bore for receiving the piston rod and top and bottom surfaces. A resilient collar is provided on the top surface of the jounce bumper. A dust shield includes a body and a planar end surface having an annular opening for receiving the piston rod. The planar end surface of the dust shield is placed against a lower surface of the washer so that their respective openings are aligned. The collar of the jounce bumper is inserted through the dust shield and the openings of the dust shield and washer to trap the planer end surface between the jounce bumper and the washer, thereby forming a subassembly.
