So I noticed the other day that my brake rotor appered to be bent. So I ordered a new one. Looking at it closer I relived that a mounting bolt had snapped off in the hub. So I Tryed to get it out with pliers no luck, it was stuck so then I tried an easy out, still no luck. I heated it up and still wouldn't budge. Long story short I decided to drill it out and re tap it. I got about halfway through it and then the drill bit bent and went of to the side into the Hub. So now half of the bolt is still there and I have a crooked hole in my hub. how hard is it to replace the rear hub? Is that something I can do my self and have it be semi straight?
