Title: Joint between cross member and side rail in a vehicle frame assembly

Abstract: A method of manufacturing a vehicle frame assembly includes the initial steps of providing first and second side rails and providing first and second cross members. Each of the first and second cross members has first and second ends extending from a central portion. A desired torsional stiffness is determined for the first cross member. In response to this determination, the first and second ends of the first cross member are enlarged so as to achieve the desired torsional stiffness for the cross member. A similar process can be conducted for the second cross member. Then, the first ends of the first and second cross members are secured to the first side rail, and the second ends of the first and second cross members are secured to the second side rail to form a vehicle frame assembly.
