Should not have any or very little in the axles or carrier. If you do, could be the thrust washer between the axle ends is shot or the carrier thrust washers are. If this is an unknown rear end, could be the babbitt washers are coming apart. If you are setting up new, I set mine for a little preload/drag. I set the one side to get correct contact between the ring and pinion then set the other side to get a little preload.
