It's an additive that you add to the gear oil to keep the clutches from
chattering. You can buy it at any good auto parts store, just ask for
limited slip additive. It will come in a tube of around 4 or 6 ounces.
Most synthetic gear oil already has the additive in it. I doubt that
the lack of the additive is causing the noise you are describing as the
bearings and gears do not require it, just the clutches in the limited
slip unit.
