I broke a lug bolt off on the rear of my 325is Friday at the track, ending my day, and yesterday I managed to get the broken piece out but in the process I buggered the threads so another lug bolt won't thread in. I'm going to get a thread chaser to see if I can clean it up enough to use, but am not hopeful of the outcome. I welcome any advice on pulling the hub to replace it. I know you have to have a hub puller and a big socket to get the nut off, and maybe I can borrow a puller somewhere.
