Abstract
A component for use in a vehicular driveshaft assembly includes a tube yoke formed from a first material and having a hollow cylindrical sleeve portion extending co-axially therefrom. A first end of a driveshaft tube, also formed from the first material, is disposed telescopically about the sleeve portion of the tube yoke and is secured thereto using conventional welding processes. A transition member includes a main body portion having a hollow cylindrical sleeve portion that extends co-axially therefrom. A second end of a driveshaft tube is disposed telescopically about the sleeve portion of the transition member and is secured thereto using conventional welding processes. A slip tube shaft formed from a second material that is different from the first material is formed having an enlarged end portion that is generally hollow and cylindrical in shape, having an outer diameter and a wall thickness that are approximately equal to the outer diameter and wall thickness of the main body portion of the transition member. The enlarged end portion of the slip tube shaft is secured to the main body portion of the transition member by friction welding.
