If I'm not mistaken, there's a special tool to remove the freehub body, but doing that is a bit pointless since the body has a very coarse thread that isn't compatible with any of the newer freehub bodies which are 14x1 thread
The freehub body can be rebuilt if it's having problems, although I can't recall if that one comes apart from the front or from the back. If yours is totally wrecked, I may have a replacement around somewhere. I don't have the special tool though. If it comes apart from the front I do have the tool to take it apart.

Billy, I think what you have is not the later Hyperglide but the early Uniglide cassette. I believe that you can unthread the small cog using two chain whips (someone correct me if I am wrong). than the rest of the cogs slide of as one piece. You cannot use hyperglide versions as the groove configuration is different. On the uniglides all the slots are the same on the hyperglide you have the one slot that is larger. I have filed off the offending larger larger area on the cog body and it works fine on the Uniglide. I think, however you have to make sure you file off the rear facing edge rather than the front so that the cassette body does not move forward when you push down on the pedals. Hope I do not have this all wrong.... Edward Albert Chappaqua, New York, U.S.A.
