Wheels keep falling off!?

[Renix]

I have a rampage xt pro and the rear wheel nuts keep loosening after a good ten minutes of running. It's funny to watch the wheel take off without the truck but getting annoying and starting to jack up the inside of the wheel. Any ideas?

Take a triangular file and sharpen the knurl on the back of the nut. Or start using blue loctite.
