Close enough!
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.
Here is the solution to this common problem i fixed my 2021 suburban with the following 3 products and saved thousands because after dealing with this problem for over a year i was going to buy a new differential but before I pulled the trigger I decided to give this cheap solution a try and it worked 100% i have zero noise or vibrations it drives perfect I love my car again. Make sure you get 2 bottles of the ACDelco 10-4091 because the differential fluid capacity is almost 2 quarts.
easy DIY project just need a little hand pump to put in the new fluid after draining the old fluid. drain plug is located at the bottom and fill up plug is at the back of the differential.
Dealerships are going to hate me for this tip Thank me later
