OK, here is the issue. I have a thumping noise when making a right or left turn. Not a gentle turn, more like turning sharply around a street corner. Speed doesn't play into it too much. Sounds like something loose,in the trunk hitting the fender, but I took everything out, including the trunk floor liner. Nothing in there except the spare tire and jack and they are secured tightly. Any ideas?

 

Is it the Mafia boss in the trunk?

 

Sounds like your lower control arms. Get them checked out.

 

You might also want to check theover the axle exhaust pipe to make sure it is nothitting.

 

is it a crunching noise

 

Nope, a thunk, like metal on metal.

 

I have the same noise in my05 Roush. I have only had the car since 9/30/07. I am taking it in to Ford (still have the bumper to bumper warranty) soon and will post the results.

 

Upper strut mounts apparently made a thunking noise while turning according to the TSB.

 

Yep, upper strut mounts can make noise but that clunk comes from the front.
I had mine replaced on my 05 GT at about 17k miles. The noise had been around for some time before I had them replaced.
I now have something else making an occasional clunk but much better than it was.

 

great and i thought, it was lack of power steering, i turn alot since i have to drive up 5 levels several times a week to park on campus, so i got use to the whinning sound or whatever is, its good to know its that, whats the tsb number on it so i can track it?
