A vehicle frame having a side/cross member joint, including a pair of side members each having at least one opening therethrough, the openings having a plurality of generally straight edge portions. A cross member is connected to the side members, wherein the one cross member is disposed in the openings in the side members. The cross member is deformed radially outwardly such that an outer surface of the cross member is formed with a pair of grooves having radially extending walls on opposite sides of each of the openings in the side member. A plurality of flat and semi-circular portions are formed in the cross member corresponding with the straight edge portions and the semi-circular edge portions of the openings.
