There are two bearings in an alternator. One (the large one) is a standard ball bearing arrangement. The other is pretty small and is a needle bearing type. Neither are really serviceable. You would have to disassemble the alternator to do it and by the time they need it the alternator is generally shot anyway. If you are hearing a squeal from that area it probably is not the alternator anyway. It is probably the belt tensioner next to the alternator and they cannot be repaired either.
