Even under extreme
conditions like racing, the hubs are pretty robust units. Mileage is a big
factor in trying to estimate condition of the hubs. There is very little
that can go bad on the hub with the exception of the bearings. Every once
in a while, you'll run into a spun wheel stud, but this is a pretty rare
occurance; a damaged wheel stud is usually due to someone mounting a tire/rim
improperly.
If the spun wheel stud is really loose, you might have to
replace the entire hub as a fix. There are no other options, as the
aluminum hub cannot be repaired from such damage. If the spun wheel stud
is still on tight, it's possible you could just punch out the old, damaged wheel
stud and put in a new one.
If you notice high-pitched squealing
localized to any one corner of the car, it's usually the bearings going
bad. The noise should change with vehicle speed.
