You seem to know your LSD's Do you know if a bad or worn LSD can cause a very loud noise that sounds like a small bomb went off in my back seat when under extreme acceleration. I have a 2011 Roush stage 3. I have eliminated everything from the clutch back to the rear end. This sounds strange but it almost seems like the pinion gear is jumping one tooth when this bang occurs. Is this even possible? Any help is appreciated .
