DV8, Have you broken down the diff to see if there is any damage to your diff casing. You might want to see about that if you have an opportunity. The Phantom grip products have blown up on dynos and now people that run dynos no longer let people on the chasis style dyno if they have a phantom grip. I know that sounds far fetched, but it has happened many times locally and I am really concerned with the Legend since the diff is attached to the oil pan. Seems like a recipe for disaster!
