I WOULD USE THE OLD FASHIONED 7-9 INCH abrasive wheel on an angle
grinder. Should be 10 minutes and the pain will be over./

Would that give you enough clearance?

Bought a brand-new hitch ball to replace the dented

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.

Grab a chisel or a cheap screwdriver. Drive it between the bumper and
the top section of the ball to see if wedging it
up some you can get a thread to engage so you can back off the nut.

The lock washer is still fully compressed.
There isn't a gap to wedge into. I don't think I lack
for axial force.

Threads, yes. Those I don't have.
