Abstract
To manufacture an axially collapsible driveshaft assembly, first and second tubular members are disposed in an axially overlapping relationship. Central portions of the concentric tubular members are then deformed into conformance with a die cavity having a non-circular cross sectional shape. The deformed first and second tubular members are then cut to provide two pairs of outer and inner tubular sections. Next, the outer tubular sections are removed from the associated inner tubular sections, and the inner tubular sections are oriented such that the deformed portions thereof are aligned with the deformed portions of the outer tubular sections. Lastly, the deformed portions of the inner tubular sections are inserted within the deformed portions of the outer tubular sections to form a pair of axially collapsible driveshaft assemblies.
