The cotter part I guess is what concerns me most with the bb. You typically need a new cotter after getting the old out correct? Suppose I could give the hub a try. Trying to manage my time with a young toddler limits my time a bit. I also have a motorcycle I have to spend some time with to get back in order to hopefully race again the end of Sept... which is priority #1 of my hobbies. The hub for whatever reason looks daunting from the illustrations though probably not as bad as it may seem. I have no clue as far as the wear and tolerances for the parts but I'm sure I could get a little help here with use of photo's. =) While it's tempting to try it myself, it might be better use of my time to have it done by someone local and have the wheels trued at the same time.
