Abstract
An automotive steering system hydraulic cylinder and method for making the cylinder are disclosed. The cylinder is attached to a rack and pinion gear assembly housing so that a piston from the assembly creates a variable displacement chamber within the cylinder. The cylinder features a smooth interior surface to provide a sealing surface with the piston and an end that has been closed by spin-forming. The method provides a means of easily fabricating such a cylinder.
