Went on a long cruise and started hearing noise from somewhere out back. Sounds like it's about the same revs as the wheels. Under power I don't hear it but coasting I do. Don't see any grease leaking (from being hot) from wheel bearings. Going to get car up to redo brake system next week. Yeah, it failed again also. So what do I do to find noise? Thanks.
