glad I found this thread. Now I know its the drivebelt. I am going to have the belt replaced and the tensioner to play it safe. If they give me crap on either I will pay to have it replaced or both if I have to.
Also been getting the rear brake squeal. They will be silencing my F at the next visit....but in a good way.
Thanks to JOEZ for the write up and DIY thread as well.
