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.

Jounce bumper and dust shield subassembly for a suspension damper

A cap having an opening mounted on the upper end of a damper includes an annular wall which encircles the cap opening and projects upwardly from an upper surface of the cap. A plurality of resilient tabs extends radially from the upper end surface of the annular wall. The lateral dimension of the tabs is slightly greater than an opening in support structure of a vehicle, e.g. a mounting tower. To quickly connect the upper end of the damper to the mounting tower, the mounted end cap is forced through the tower opening to compress the tabs. As the tabs clear the tower opening, each tab springs radially outwardly to retain the damper in place.

Mounting assembly and method for a damper

The strut mount is secured to the piston rod of the damper of the strut and provides the upper seat for the suspension spring. A support plate with a coned opening cams a snap ring held in the isolator or rubber body of the mount radially inwardly. At the top of the coned opening, the snap ring deflects radially outwardly over the top of the coned opening to engage the upper surface thereof to lock the isolator and the strut in position.
