Abstract
In one aspect, the invention is directed to a half-cradle for use in a vehicle frame. The half-cradle includes a cast end member formed from a first material and first and second tubular cross-member stubs extending from the cast end member. The first and second tubular cross-member stubs are made from a second material. Each of the stubs has an end buried in the cast end member, wherein the buried end is uncapped. Each of the tubular cross-member stubs has an interior that is configured to sealingly receive a core for use in preventing the filling of the stub with molten first material during casting of the cast end member.
