rear hub studs sheared off??
Discussion
driving to work this morning I heard this regular squeak, touched the brakes it stopped, a few miles later it was there again so I pull over, the nearside rear wheel was missing a wheel nut, the stud has sheared off?? hopefully it will get me home this evening like driving miss daisy.
has this happened before? any idea why? I have done over 500 miles the last week and its been great...

I have had this happen to mine in the past (admittedly on track). It was caused by the nuts being under torqued. They had originally been torqued correctly but the wheel in question had been recently refurbed and i have been told the paint can compress and then cause the nut to become undertorqued (might be bs). I drove from Castle Combe to Farnborough with the remaining 3 nuts and it was fine although i was driving like Miss Daisy. 😉
This can happen when lug nuts are over-torqued, too. I've seen narrow spots on studs where they've stretched after some gorilla at the tire shop over tightened the lugs with his impact gun. Always use a torque wrench to tighten your lugs, and make sure that anyone who works on your car does the same. Whenever I get my car back from a shop that had to remove the wheels, I loosen and torque the lugs to be sure - if loosening any of the lugs is especially difficult, I inspect the stud for damage. After driving the car for a bit (like a hundred miles), I re torque the wheels one more time.
Oh, and please use a decent torque wrench. Some of the really cheap, imported, no-name-brand wrenches are ridiculously inaccurate. One that I measured would apply over double the torque that it was set to. No wonder the owner of that wrench kept breaking studs...

I was about to say exactly what Jim has.... sounds like they were actually over torqued at some stage to me, causes damage to the stud and they can sheer and come loose easily.
However I have had similar in one of my cars a few years back when someone tried to steel the wheels and was foiled by the 'lock nut'... basically car was driven not knowing it had occurred and the lock nut came loose and sheered all the studs eventually (I wasn't driving lol). So your nuts coming loose will have stressed them massively and the reason they were so easy to break.
