[NASSTY]

100ml bottle of modifier was about $12. The guys I know using it haven't looked back. Their diffs quieten'd up a lot as well as the clutch packs in their LSD's worked more progressively. As I understand it, the problem with oils is that they keep on changing composition but we still use diffs that are almost 30 years old. I'd give it a go before taking the diff to a specialist. Mike Roddy rebuild my diff. It's a 3.07 LSD.
