I used the GM oil and a cheap Amazon transfer pump made the job easier than squeezing the bag. I do like that setup

Thanks for the video! When you had the problem could you hear the grumbling all the time? I can hear it all the time, more so on highway with new tires. I just put the car up and sure enough when I turn the wheel I can hear the sound and it sounds like its coming from the rear differential. Only 97k on the car.

On mine I could mostly hear it when I was driving in a parking lot or doing tight turns, not when I was driving the car straight down the road. It didn't go away for me until I used the Mobil 1 and the GM differential additive. The gear oil with the additive already in it didn't work for me.

@@theazguy Do you know if you 08 has a limited slip rear end (should have code g80 in the trunk parts list). I just pulled the fluid on ours, fluid is golden clean. I looked up the alldata on the car and it could have a limited slip diff or non. Limited both rear tires would spin in the same direction when lifted off ground.

Update: After changing out the fluid there was still a grumbling sound when doing low speed turns. I ended up changing the fluid again using the GM 4 oz limited slip additive and some Mobile 1 synthetic gear oil. After that the grumbling sound went away. The Valvoline gear oil stated it had the friction modifier already in it but it didn't seem to work well for this application.

@iSaid209 after using that Valvoline gear oil and not using the limited-slip additive the car would still make a grumbling sound while doing turns in a parking lot. I ended up replacing the gear oil again with Mobil 1 and I added 4 Oz of the limited-slip additive and that completely removed the noise.

Hey I'm interested in a 2014 Cadillac ATS with 55,000 miles on it and I've seen some people said they're rear differential went bad and some people that said they never replaced/ repair their rear differential. Does changing the differential fluid prevent rear differential problems?
