Rear end issues.

I have a 21 Yukon w almost 40k miles on it now and the rear end is having issues. At slow speeds after the vehicle has sat over night, the rear end locks up until we get a mile or 2 on it. After that, it drives normal. It makes a grinding whining noise like a 4wd making a 90° turn. Fluid was full as well. Dealer called and said only the fluid has to be changed and no damage was done to the diff. I would've thought after all the grinding and whining noises sometimes would've been damaged. Is changing the fluid only putting a Bandaid on it?

Never thought of that. GM forced me into 3 yrs so thanks for the tip! -
Drove by my dealer this morning and he said they're dropping like flies still. He said I have to drop it off next week at the end of a day and they'll give me a loaner. It will need to sit overnight like the bulletin states so they can get a morning cold start. He said it'll get a set of lifters by the way all my videos sound.. He joked and asked if I had a CEL light yet and when I said no, he said I will soon.
