Running and/or sitting long periods of time with low gear lube will cause those bearings and seals to dry up and go bad. A full diff housing allows for the lube to partially fill each axle tube with gear lube before reaching the bottom of the fill hole. It's important to be on a level surface when you check or fill the diff so both those bearings get lubed. It's also important to check the vent making sure it's open and not clogged. You can see in the pic that that bearing was dry, "bad juju!"
