21 suburban 2wd rear end fluid capacity
Great, thank you. I tried 75w-90 and I still have the noise from the rear differential. I guess I am going to have to try the AcDelco and see if the noise goes away.- Tgoody

I have a 21 Suburban 2wd with the G86 rear end. I had a vibration and the dealership said there is a TSB that says to change the rear end fluid 3 times. So that is what I am doing as the dealership wanted over $1100. It has been difficult because I cannot find much information. The good part is...- Tgoody
