rearend fluid level question

well the bearings were shot and I replaced all the bearings, seals and the axle flange gaskets. Hopefully that will take care of the problem. Tyler has a small rumble in his car so I am going to get his in and check the bearings on his axle. I can imagine what those look like. Pulled that rearend out of a 67 Coronet that had been sitting. Had no intension on running it until it was gone through but as luck would have it, it has been running for a couple of years now and all over the tri- state. So I guess I need to look at it before my luck runs out. Thanks
