Rear Axel Nut

[pickles]

So I got a flat tire. was having trouble with the axel nut over on the side with the muffler
the service manual says

"Remove the rear axle nut"

This has proven not to be as simple as seemed.
I used a 19mm wrench and a 17mm on the other side.
it WILL turn, but the other side does as well. I fear ive almost stripped them, they do have significant damage as well as the socket/wrench im using.

ive seen tutorials where people just use one 19mm wrench with a pipe for leverage.
Whats wrong here? I tried a torch, as well as locktite.
I suspect I need a differant tool, the suzuki one is 100 and its just a peice of metal
any help or anyone been through this?

I wish i would have just rode it to the dealership


will upload pictures soon.


thanks guys
