Well, I keep finding new noises in my truck. The Failing DMF (which is hopefully coming out tuesday) has so far rattled, knock, and hissed. It's causing a noise similar to an exhaust leak. But now there's a new noise. It's sounds like turning a wheel bearing (dry) around in your hand. When I did my back brakes, I had the drums turned. I thought I had all the metal shavings out, but if I happened to leave some in the hub, would they eat a wheel bearing in just 150 miles? Or is this just another noise from the flywheel? It only does it when you're moving though.
