If you over tighten the axle nut and drive for a little and the shaft pops out, is the shaft toast and needs to be replaced, or can you re-set it?

Thanks,

Edit: My noobness: I didn't have the shaft all the way in. It popped out. I took it apart, got it in the additional 1/8 of an inch and could no longer "overtighen" the axle nut.
