The one on the other side, yet unmodified, is a bit loose, and difficult to tighten because it's hard to get a grip upon the square nuts where they are inside the bar. My version makes it easier to get at the back fasteners.
Once it gets loose it will indeed work the mounting holes larger until they tear. This all happened before I received the trailer.
I was wary of unbolting the torsion bar, even with the shell up and it's weight holding the shell support bar down upon the torsion bar (don't ever do it with the shell down!). I don't know if there is any twist (and thus stored energy) in it in that position. Others should approach this carefully or leave it to a professional mechanic, at least until we find out if there is force stored in the bar while it's up. If that force releases suddenly, pieces will go flying and could hurt or kill. Someone who has parted down a TM could tell us how it behaved during disassembly..
