The noise has not come back since I have posted this thread. Since I have been reading some of problems with spun bearings, I guess I am a little paranoid about any new sound coming from the engine bay especially if it sounds like a knock. I do think the noise will come back since cars can't fix themselves. Can anyone confirm if there is a knocking noise caused by a spun bearing that the noise is not intermittent and gets louder at higher RPMs?
