take the nuts off the axle then you might need to tap sprocket hub off,
it might help if you can have someone sit on bike (big person) and have them hold rear brake.
then you get a pipe wrench or a cresent wrench with a breaker bar, if needed. and once you get all that off
get a block of wood put it against axle and tap it out through the carrier. dont forget to take
brake caliaper off
