> 3 dayThis stuff works!!!, My rear diff. in my 04 gmc yukon 5.3 L had a whinning sound when making sharp turns, I had the fluid in the pumpkin replaced a few days ago and it was still making the whining noise going into a sharp turn so i picked this stuff up at a auto parts store in my area , i had not heard about this stuff prior to buying it, but wanted to give it a try at only 8 bucks a tube, so i added some to the fill hole on the rear diff and drove about 20 miles to mix the additive with the rear diff fluid, well and i also went into a parking lot and made some sharp turns and presto noooo more noise!!!! im a happy camper!! I wanted to give this stuff 5 stars because im that impressed, but i`ll see how long it holds up.

> 3 dayI 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.

Greater than one weekInstalled new gears which I purchased here and since my 67 GTO has Safe-T-Track, it requires this additive. Works as it should, just pour the complete contents into the rear end prior to filling with fluid. This helps it mix itself when you add the diff. fluid (which I also purchased here).
