A method of manufacturing a hollow structural frame rail includes rotating a tube relative to a tool to reduce an outside diameter of the tube at predetermined positions along the length of the tube. An elastomeric insert is positioned within the tube. The tube is bent at a location containing the insert. The bent tube is hydroformed to define a finished shape of the frame rail.
