So in my rage of working on my grizzly 660 when removing the rear knuckle to replace the wheel bearing it was locked up on the cv axle so I took a hammer to the axle end to try and pop it through. Then to realize what I’ve done and now I mushroomed the outside thread enough where I cant get the axle nut on. Anybody have any ideas as of what to do. It’s a heavy duty axle and I don’t want to have to replace it for such a stupid issue but my thread kit isnt that big. Diameter of the thread is .8

Thanks
