**need Help On Installing Rear Sprocket

I cant seem to get the freewheel hub off
i need some help getting off...what do i use to get it off and how
would also be great if someone had some step by step directions on how to do it
thanx

I know its not the perferred method but I cut mine off with a dremel. I cut it down till I was barely nicking the threads. Then I basted it in wd-40 and was able to get enough flex from the cut & lbe from the WD to get it unscrewed. Then the day after I put, remounted everything on I decided to buy a set of bling bling rims, lol.
