i use a 1" 3 fool long bar through the rear sprocket over the swing arm and wheel and use a breaker bar to loosen it but beware if you use your arms when it go’s it will smack your fingers in the nerf don’t use an extension bar put the socket on the nut with just the breaker bar and use your foot on the bar it will go, once you stop the rear wheels turning it will go fairly easy

Try heating up the nut, then spray PB blaster around the front of the nut. Let sit a few, tap the nut and spray some more. Give it a few more and hit it with an impact.. Use a nozzle attachment, to concentrate the spray between the nut and whatever it's attached to..
