I promise you that castle nuts are not one time use. There is a lot of things recommended by manufacturers that are completely unnecessary. OP don't bother buying a new one unless yours is damaged. I never replace them (unless they are damaged) at work and I've literally replaced hundreds of hub assemblies. Never had a single issue with reusing one.Bulloch,
Two Ford dealers told me it is a one time use bolt along with searching the forums. There's was an answer I read about it forming or some **** after it gets to to spec.
Bolt or nut? I'm not claiming to know 100% that it's not a mechanical lock nut..... but it would be highly unlikely that it would be. Bearings must be packed with grease... and have proper pre-load set on them which is typically done with a castle nut and cotter pin; not a lock nut. If it is in fact a mechanical lock nut I agree it should be replaced. If it's a castle nut, there is no reason to ever replace it unless it is cross threaded or has damaged threads for some other reason.Bulloch,

Don't hate on my Haynes manual bitch! That thing saved me tons of money before I knew anything about cars!IDK either.... Haynes and other manuals suck 90% of the time. Either way, if it's a castle nut its re-usable; if it's a mechanical lock nut replace it.
Your shop forrman is taking a big risk for saving the customer a few bucks. One failure and your shop will be the crap sued out of them. Just saying.Never had a single issue with reusing one.
