My Evo makes a goofy noise whenever the terrain under me is not entirely smooth. Whatever it is, its not effecting performance but If you don't have the stereo on it's really annoying. Its almost like a creaking but its not high pitched enough to be a creak. It sounds more like something jiggling around but it never changes positions. It always sounds like its coming from the front drivers's side. Any ideas? Think it's worth a trip to the dealer ship?
