I have a 2019 Yukon 5.3. I just changed the front diff. I only removed about 2.3 pints, it says that it is supposed to hold 3 pints. I had the front up on stands when I drained it, and when I went to fill it, it took almost 2 quarts and it hadn't started to run out yet. I then put it down off the stands and it just wanted to drip out the fill hole. I let it drip for a while and then I jacked it back up and tightened the fill plug. It ended up taking about 1.85 quarts, but everything I read said 1.5 quarts (3 pints). I poured out what came out and it was 37 oz. which is 1.15 quarts. Could it have gotten that low with 48,000 miles on it?
