Changed front and rear differential lube and transfer case. Oil and filter and tire rotation. Sucked 2.5 qts out of trans thru Fitz stick did it cold that's all that came out.
Try facebook I sold my F150 to a guy five hours away within 30 minutes of posting it. It was a 2018 XLT 4x4 amazing how stuff sells on there. I will never trade a vehicle in again.
I hate it when they say that. They can be in the vehicle with you while it is doing it and they will still say it. That is why I traded my Frontier in on my Ranger it had very noticeable rear diff noise and said we do not hear it.
