Default Slip Additive in Moser 9Inch???

My rear end whines too much on the highway and I was wondering if I could put a bottle of GM's limited slip additive to help the whine? I have a bottle sitting around.

It's not the diff making the whine. It's more than likely a bad gear install. What ratio you running, and did you have a shop re-verify that the gear pattern was good?

No, the additive won't help. Switching over to a thicker gear lube such as a 140 weight might quiet the noise down. Bob
