Sooo. I'm replacing the 2 5/16" ball on my receiver. It's a 1 1/4" shank. The nut on the existing one has worked loose enough that it rattles around and messed up the threads so I can't tighten it back up. I'm going to use a 4 1/2" cut off wheel to zip it off of the receiver. on the new one I will tighten it as much as possible with a 3/4" air wrench, also use blue loc-tite. My question is would it hurt to put a couple of tack welds to the receiver? Possibly one on the nut at threads also, to keep the new one from working loose. Thanks Crete
