Abstract: A method of mounting a suspension bumper (10) in a motor vehicle providing a high degree of manufacturing confidence. The method includes inserting a first end (54) of an installation tool (50) in a blind bore (20) of the suspension bumper; aligning a retaining tip (40) with an aperture (44) in the vehicle; applying an insertion force (60) on the suspension bumper to compress the retaining tip through the aperture and allow a retaining groove (48) to engage a periphery (49) of the aperture; and applying a withdrawal force in a direction opposite from the insertion force sufficient to remove the installation tool from the suspension bumper, the withdrawal force being smaller in magnitude than a force required to disengage the retaining groove from the periphery.
