As long as your axle bolt is straight... just threading it in by hand without wheel would be good enough for me. If it spins in all the way easy and smooth that should be good enough and rule out a bent swing arm without crazy, difficult measurements.
You have a few threads going about this, and been offered good advise. But you left out lots of things, then dropped in a low side. The second wheel you bought used... did you change the bearing? Did it press in tight? Or did you just install the wheel with old bearings?
Your first wheel bearing issue, did you buy the bike new? Or was there a PO for that as well? What bearing is it? One or both?
I'm just asking to help with diagnosis. This whole thing is weird.
Odd for sure.
