Good stuff! Here is how i used it: How to change the differential fluid in a 2012 Dodge Challenger 3.6 liter. Link: https://www.youtube.com/watch?v=3HJ6zoGZy5k

I bought this for a 2020 Ram 1500 classic. The additive seems to work but my rear end still makes an ever so slight noise upon sharp turns when accelerating, and when its cold. Now when I say it makes a noise you have to really listen for it and it only last 1 or 2seconds then its over with. And from what I have read this is a normal occurance for this type limited slip rear end. I dont remember it making the noise before the oil change, but I wasnt listening for it either, and after the oil change I was listening for it. So Im going to say its fine. The noise hasnt got any worse, and doesnt do it regularly.

As advertised

easy to use and will quiet noises from limited slip rear end

Three stars because it probably will work for some but it didn’t fix the chatter on my F-150. The Motorcraft XL-3 stuff did though.

Seems to be working as expected. Only been installed for about 500 miles.
