ok, got my wheel bearings today and was going to replace the 3 in my rear wheel...slight problem though, the bearing on my brake disc side has somehow separated. the inner race has come out, along with the balls, but the outer race is still inside the hub. how in the hell am i going to get that out now?!? any tips? there's only a mm of the outer race jutting out, which is not enough for me to use something to pound it out!
