ABSTRACT:
A method of forming a receiver tube for a motor vehicle trailer hitch assembly. The method involves a forming operation in which a length of square tube stock is mechanically formed to define a reinforcing bead around the hitch receiving end of the tube. The process further partially forms and sizes the inside surface of the tube. The resulting receiver tube improves over prior art multi-piece constructions in terms of appearance and corrosion resistance.
