A method of welding together a motor vehicle structural assembly is available. The vehicle structural assembly includes a boxed member including an outboard wall, a top wall, a bottom wall and an inboard wall spaced from the outboard wall. The inboard wall has an opening therein. The motor vehicle structural assembly also includes a cylindrical support including a first end and a shoulder spaced from the first end at least the distance the boxed member inboard wall is spaced from the boxed member outboard wall. The method comprises spinning the support and advancing the support through the inboard wall opening so that the support first end is friction welded to the outboard wall and so that the support shoulder is friction welded to the inboard wall.
