I made my own because I'm able to, they're kind of pricey to buy, but they do work.
I went through this on my Wife's Vibe last fall and just welded up my own out of scrap steel I had lying around, and yes I tried heat (oxy acetylene), and an air chisel, all the tools I've been using over the past 50 years turning wrenches to break rusty corroded parts loose. This tool I made was the last choice, and it did work. I've taken a lot of frozen parts apart in the last 50 years, this was one of the toughest parts to disassemble I've run across in all those years.
Without one of these hub buster tools, and a BFH, I doubt you'll be able to do it at home.
