Abstract
A method of manufacturing a drive line assembly includes the initial step of providing a driveshaft tube formed from a metallic material and having a substantially uniform wall thickness. The driveshaft tube terminates in an axially extending cylindrical end portion. Then, a diameter reducing portion is provided that is formed from a metallic material and has a substantially uniform wall thickness. The diameter reducing portion includes an axially extending cylindrical first end which is co-axial with and permanently fixed to the axially extending cylindrical end portion of the driveshaft tube. The diameter reducing portion further includes an axially extending cylindrical second end. The axially extending cylindrical first end of the diameter reducing portion defines a first diameter, and the axially extending cylindrical second end of the diameter reducing portion defines a second diameter. The first diameter is larger than the second diameter. Lastly, a tube yoke is provided that is formed from a metallic material and includes a pair of opposed lug ears having respective orifices formed therethrough. The tube yoke includes an axially extending cylindrical end portion which is co-axial with and permanently fixed to the axially extending cylindrical second end of the diameter reducing portion for axial and rotational movement therewith.
