Abstract: A method of manufacturing a shock absorber includes inserting a floating piston into a tube, disposing oil into the tube, and inserting a piston-rod assembly into the tube. The piston-rod assembly has a piston coupled to a rod. The method includes inserting a rod guide assembly into the tube. The rod guide assembly includes a sintered metal rod guide having a seat and a seal disposed in the seat. The rod extends through the seal. The method also includes deforming a wall of the tube into engagement with the sintered metal rod guide to provide a piston-cylinder assembly and inhibit axial movement of the rod guide assembly relative to the tube. The method further includes pressurizing the piston-cylinder assembly and forming a flange portion of the tube over an upper surface of the sintered metal rod guide.
