A method and apparatus for assembling combination shock absorbers and leveling struts of the type comprising a telescopic direct acting shock absorber having a reciprocable piston and piston rod, with the piston rod carrying a cylindrical dirt shield which cooperates with a rolling or flexible diaphragm member extending between the body of the shock absorber and the dirt shield in defining a variable volume pressurizable chamber. The dirt shield is displaced relative to the shock absorber in response to the magnitude of pressure maintained in the chamber whereby to selectively control the attitude between sprung and unsprung portions of a vehicle. The method and apparatus of the present invention includes means for initially inserting one end of the diaphragm around the body of the shock absorber for selectively gauging the axial location thereon and thereafter for crimping a suitable clamping ring around the outer periphery of one end of the diaphragm so as to fixedly and sealingly secure the one end to the body of the shock absorber. Means are then provided for selectively inverting an opposite end of the diaphragm, for sleeving the same over the adjacent end of the dirt shield, and for pressurizing the unit so as to properly axially position the diaphragm with respect to the dirt shield. In this position, the opposite end of the diaphragm is clampingly secured to the end of the dirt shield, whereby the diaphragm and dirt shield will cooperate with the body of the shock absorber in defining the aforesaid pressurizable chamber.
