Need help with diff whine?

So I wanted to share my experience with trying to eliminate diff whine.

So originally I was running Turner solid diff mounts to help with broken diff bolts and Axel hop that had caused a lot of Carnage. The whine was bad and I lived with it for a year. I decided to do an super 8.8 swap it has a Torsen T2R differential and is known for being noisy even when using factory rubber mounts. I had mounted it solid with steel mounts no bushings at all. The whine was horrible.

So I had remembered an old dynamat display with the bell and had the idea of using something similar.


I decided to go with Rockville rockmat as it is cheap butyl rubber and has an adhesive that is good to 300 f . Cost less then $15

I had used two strips at the front of the sub frame and back at the top most part closest to the body. I had also stuck a chunk on the top of the diff.

Well it worked no more whine. I have been running it like this for about two months the adhesive is holding with no signs of delamination from the heat under the car.

I know my set up is different then everyone else but the concept should work the same. I hope this can help quiet some differentials.

Yes I know this stuff is made for car audio.
