happened to me on a number of occasions.  once in the tiger and another
time in my mercedes rally car.    both times, annoying, but no harm done.
a lot more 'disturbing' things have happened to me ;)

using new studs and accurately torquing the nuts with a torque wrench (and
rechecking them after a few miles) should prevent all but the most abusive
modes of failure (i.e. large sticky tires and an LSD).

even a wonderfully fat, mega strong stud will fail if under or over torqued=
.
