Thank you and I couldn’t believe it when the owners manual didn’t give any information. I am not sure if this reply will include @915_Tahoe but my VIN is 1GNSCFKDXMR346696.

@Tgoody you have a response, hope it helps

I guess I should get an opinion if 75W-90 is ok because Chevy says 75W-80, which I can’t really find locally.

Thank you,

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.
