Other Alternators have lasted 75k - 250k ... I usually will replace bearings when other high mileage maintainence requires vehicle to be down long enough to go to alternator shop and be 'checked out' (there is a good local alterantor/starter guy).
8766hrs is a 'year' at 50mph is 435,330 miles. Make sure you have a good seat if you drive that much a year.
