Thought of that too, since my air box is missing one clip. I already opened it up all the way and there was no difference, then I held it closed and the same. I just want to know if I'm going to wreck something by driving it.

From what some people have told me, bearing noise is usually a low pitch sound not the one I have.

So, would I be safe driving it? Maybe I'll bring it by a garage and see if they can hear my mystery sound.
