Leaf spring pads are polly ones that are brand new. So I don't think it would be that.

I hope I didn't break an axle tube. I have seen that before but thinking it would worse if that was the case. I have a eaton 3:36 setup in a 8.2. Almost everything has been replaced on this car.

I was wondering if the front perches for the leafs could be moving a little with the torq. I only hear the noise on a hard take off and/or a hard stop.
