X2!! I had to drop the oil pan several times in less than a week trying to stop a leak from the screw that connects the oil cooler lines. I originally was thinking it was the oil pan gasket.Just pull the bolts that mount the front diff to the frame and let it droop. It’s just enough room to get the pan off, I’ve done it on my 02 Denali. Might have to pry down a bit on the diff while you wiggle the pan out but it’s not hard.
