Magic in a bottle
I would have never guessed that 4oz of an additive could make such a huge difference. My 'Cuda has a 3.55:1 Auburn posi in it. Even though I use limited slip gear oil, it would chatter and buck when I would turn the car. It was embarrassing and worrisome when I would back into or out of a parking space because it was so loud. Auburn is known to have issues of this type due the their clutch cone material. Added the full bottle into the read end and I was stunned. Before I found a parking lot to do figure 8s with, to mix it up and work it in, the rear end was already quiet. At speed, the car would feel somewhat rough... that has been eliminated. It worked so well that I was worried the posi would slip, so I found a vacant road to test it. After three fast starts, all of the marks showed exactly the same start and stop of tire spin.

Yukon Magic!
This stuff is magic. Have a 2021 GMC Yukon xl AT4 and rear differential started groaning on slow turns on a cold start. Had dealership flush and add new oil. The groaning diminished a little but was still there. So I drained the new oil and added Yukon Friction modifier with AC Delco modifier and 2 bottles of AC Delco synthetic rear axl oil. Did 4 figure 8s and the groaning is all gone. Sounds like brand new. This is a common problem with this vehicle. And this is the solution.

Highly rated additive. Shipped by a seller I purchase from frequently. Easy to add to oil and a good value. Strong odor though.
