Chances are it is a bearing in the differential. It could be one of the pinion bearings, or one of the bearings on the yoke (one inside the diff and one on the outside under the pinion seal. As far as just looking, it is hard to tell. It will actually need taken apart to see if there is damage to the roller bearings or the race.
