I am in the middle of doing the same thing only i cant get the stupid axle out.I have had problems the whole way with this thing. my axle nut didnt have the oem nuts on it so i had to end up going and getting a 24" pipe wrench and stepping on it to get them off and i am have problems with getting the axle to break loose from the sprocket carrier. any ideas such as a puller made or something.
