don't know if anyone will be able to answer this or not, but here goes:
I've got my old 4.3 diff laying around, I've been thinking of putting it back in while I replace the shaft seals in my Torsen, but it makes an odd noise. When the output shafts are turned in opposing directions, there is a very audible gear noise sound, seemingly from the spider gears. It's not a grinding sound, more like you can just hear the gear teeth in the spiders as they mesh with each other. My question is - is this normal for a non-lsd diff? Or is it shot? It's got ~142k on it.
