What funny is it only does it under a HARD load, you really have to romp on it to get it to do it, it will do it while turning but again only on a hard load. It acts like soemthing is trying to engage, and it wasn't doing it all that often, it does seem to be getting worse though. Axels area easy enough, especially on that side, I've replaced the hub twice in the last six months, so I guess I'll do the axel when I put the sway's in.
