I have an exhust leak due to a broken bolt in the exhaust manifold in my 2002 expedition (5.4). I've taken it to two garages and both places could not get it out. Does anyone have any advice?

This is unfortunately a common problem for 5.4L engines. Persoanlly I'd raise hell with the dealer for a 3 year old truck. They might cut you a brake. THere is a TSB related to this problem. Partial text follows:
