I have a 1997 A4 1.8t quattro with 130000 km on it. For the 2 years after a long drive, I start to hear squealing from the rear right tire i believe. It sounds like metal on metal - very high pitched. I have replaced the tires and rims but the noise persists. It goes away if i pull the parking brake up slightly and then release it. The noise comes when i'm driving at highway speeds or city speeds in a straight line or in turns, whether im braking or not. As soon as i let the wheels cool down tho it goes away. im thinking its a wheel bearing but not sure.
If anyone has advice - please post a reply - but preferably if you could email me at hitman247 at hotmail dot com
Thanks alot guys G
