Bought a brand-new hitch ball to replace the dented
and cruddy old junky looking thing.

Whilst tightening it with medium force (using a short
1/2" ratchet without a cheater) I managed to strip
the nut threads (I think). The thing is now stuck in
the bumper and the nut just rotates backwards without
unthreading if I attempt to back it off.

Right now, I'm thinking that I will carve a slot
up the male thread and cleave the nut in two using
an angle grinder and cutting disk.

Better idears, please.

Just a thought....If there's enough room there and you could borrow a
large enough nut splitter the job would almost do itself:

I've had a couple of sizes of nut splitters in my "hell box" for 30+
years and every so often one comes in handy.
