Damaged, improperly greased or misadjusted wheel bearings, most common if
you have the older style tapered roller bearings. Ray didn't overlook this,
it's merely an expansion of his comment "improper rotor installation."

One other problem - very rare in my experience, is an improperly remachined
rotor. Many years ago I had disks turned by an auto parts store that owned
their own brake lathe. The lathe's collet was out of true.
