have a bumping noise under car that has been there for over a year an just keeps getting louder, it will do it when driving an sounds like a exhaust pipe moving. I have checked everything an cannot seems to pinpoint it and it does not do it all the time. Talked to the ford dealer an they said they will just have to start trying things because they have not run into this before. Any help out there?

Hard to diagnose noises over the internet really, but can you post a video of the sound and we will give it a shot. Likely something lose like you mentioned the exhaust. Depending on what it sounds like it could be control arms or something like that starting to fail. How many miles on the car?

My internet guess would be suspension bushing or exhaust hangers.

Start by checking your swaybar links...

I think crjackson2134 might be right. I recently experienced the same thing and it turned out it was my lower control arms and the bushings. Also, if the car squeaks like when you go over speed bumbs then just lubricate it

My 2012 had a broken sway bar end link. That would be something to check also.

My 2012 had a worn end link and it took took me forever to track down the noise. I would start with them.

If it helps, see tido2K's thread

So what was it?
