Thanks for the replies, I guess the wheel is acctually called a rolling landslide.
I worked on it last night & was able to get the bracket off & in the vise. I got it to spin a little with the help of a 24" pipe wrench, then with the puller was able to get it apart. I think the heating & cooling helped, its a tight pressed fit with no rust on the surfaces where they were together. The wheel is shot & still stuck on the axel & the hub has been welded in three places. I am going to see if I can find a trailer stub axel & hub that will fit and then just make a new wheel to fit.
