Okay, here is what I do and so far it's worked perfectly. When installing the wheels make sure everything is clean, apply a thin coat of gray anti seize grease to the beveled surfaces and a little on the threads.. install wheel and seat it with the wing nuts. Give the wing nuts a few good smacks to make sure it's tight. Install safety wire, basically the SS wire just tells you at a glance the wheel is still tight when doing a walk around.
Removing the wheel, jack up the wheel so there is just enough pressure on it to keep it from spinning when you hit the wing nut with your lead hammer.
Apply a great amount of W-D-40 to the threads and let it soak. Now start beating the crap out of the wing nut, rotating the wheel so you can smack each wing on the knock-off wing nut.
