ABSTRACT:
A vehicle part suitable to form a part of a rigid vehicle assembly, such as a vehicle frame assembly or the like. The vehicle part is formed from a cylindrical blank having a predetermined wall thickness and a predetermined peripheral dimension. The cylindrical blank is bent and hydroformed to provide a tubular wall having a central bend therein of at least approximately 30.degree. and opposite angularly related end portions. The central bend has a peripheral dimension in excess of approximately 10% of the predetermined peripheral dimension of the cylindrical blank. The central bend includes a concave portion free of wrinkles and a convex portion having a wall thickness within plus or minus 10% of the predetermined wall thickness of the cylindrical blank.
