A vehicle frame assembly includes a side rail formed from a first side rail member including an end portion having a closed cross sectional shape and a second side rail member including an end portion having an open cross sectional shape. The cross sectional shapes of the end portions of the first and second side rail members may be formed having either a rectilinear, circular, or other cross sectional shape. Preferably, the end portions of the first and second side rail members are formed having complementary cross sectional shapes. To form a joint between the first and second side rail members, the end portions thereof are arranged in a telescoping relationship. Then, the end portions are secured together, such as by welding. If desired, one or more notches may be formed in one of the side rail members to facilitate the welding process and to provide additional welding junctions between the first and second side rail sections.
