So the 2" square tube hitch is rusted into the bumper's receiver, pretty well frozen. I managed to get the hitch pin out with a little hammering. The back side of the receiver is open, so I have access to that side as well.

I've been soaking it with rust penetrating lube for a few days...

This is what it looks like from the back side...

I've tried hitting it with a hammer (regular hammer, not a sledge type BFH) & brass punch from the back side but it's not budging. What to do? Just keep soaking with the rust lube and hammering till it pops out? I was thinking an air chisel might help but I don't have one of those. <img src="/forums/images/graemlins/confused.gif" alt="" /> Whatchyall think?
