Hope your right cause Im same boat and planning to chase this problem in 1000k when I hit the 20k mark.
Yup, it's on my 4 page invoice from picking up the truck today. Also on order (from US) is my new front left axle assembly. I had more than one type of clunk (but I didn't break it on purpose...)
Trick is to befriend your service advisor at the dealer. He just beams when I drive in, as my exhaust rattles the windows in there, and he knows I drive it like it was meant to be driven. I've had hoses/lines replaced that Ford will never know about, but its due to being nice, respectful, knowledgeable, and handing him the occasional TSB he's never seen before!
