What sounded like an axle bearing to the far far right of my car apparently, isn't. I replaced it two weeks ago, and the noise returned the day I finished replacing it. So I'm fairly content in saying that wasn't it. I was told that it could be the brake, but I don't know what I should check. I'm fairly sure I need new pads back there, just because I don't know how long the previous owner had them on for, along with the front pads, but I'm not sure if I'm going on a wild goose chase.
