Hi Everyone!

I have been a FREQUENT viewer of this forum but this will be my first post.
I currently drive the Alabaster White 2004 XFire Coupe. 50k miles --- been driving it since it had around 30k. A few months back, I began to heard a noise coming from under the hood, to me, it sort of sounds like a grinding/churning noise. I only notice it when I am either in a drive-thru or at a stop light.

The noise is very hard to explain but I think grinding/churning is fairly accurate; the churning almost has like a repetitive tick; as if maybe something is turning and again "grinding/churning"

I have taken it to Chrysler dealership twice and had the service mechanics looks at it. One who was a "Crossfire Specialist" ---- He found nothing at all wrong. While I understand..he is a professional...I know my car and I know when I originalyl bought it, it was not making this noise so I am PRETTY sure...that SOMETHING is going on; I just can't imagine what it is.

Have any of you heard this noise or would you have any clue at all as to what it could be? Any advice would be greatly appreciated.

I am at the point now where I am considering trading my car in for another Alabaster Coupe just to get rid of the noise but if I do that, I will lose financially --- so I would "prefer" not to.

Anyone?
