Take it back to dealer, and let they do the work. My dealer charged me $220 for it. If as stated above, the "Big gun" costs $180, then it might be more wothy it to let dealer handle the work(and let they have the blame when it fails again, maybe?? :p)...
P.S. Mine failed at the rear, passn side, too....
