Gear whine is not a positive indication of impending complete failure. Have you noticed the gear whine from some commercial vehicles? Gear whine used to be common on all forms of gears if they were rotating quickly enough, with modern gear cutting machinery annd modern gear forms we have come to expect quiet running. I think the eventual failure will be loss of drive.
