I've had a low speed (like 0 to 10 mph) sort of growling noise for a long time, already replaced the front hubs (had play) and front/rear pads and rear rotors, noise still there. Now thinking it must the the rear hubs. I'm guessing they're more of a PITA than the front's due to having to deal with the parking brake cable. For anyone that's done this, how hard is it to detach/attach the cable, if that's even necessary?
With the wheel and brake calipers removed and turning by hand, the rear hubs don't make the same noise, but they do make some rubbing noise, but then that's with no load on them.
