Rear Stance Height Different Between Driver and Passenger

[SidFarcus]

Looking at back of my Yukon in the driveway, I noticed the driver side and passenger side look to be at different heights. Grabbed a tape measure and confirmed there is a inch and a half difference. Rear shocks have been replace in the past year even though I know shocks have no bearing on height. Am I looking at a bad or broken spring? Anything else I can look at under the rear to diagnose?

Passenger Side: 37.5 inches

I have the same problem and the only possible answer I got is leaf springs. The other is gas tank weighing the other side down.

So I have my Yukon up on ramps in the front backed into the driveway that has a slight incline. I measured again the height in the rear from the ground to the start of wheel well on both sides. The driver side rear is 39 inches and the passenger side rear is 36 1/4 inches. Three inches seem like a big difference between the two sides. I looked at the coil spring on the passenger side and it doesn't seem to be broken.

You're not looking at anything that's broken...what you're seeing is known as the "Chevy Lean".  Google "Chevy Lean" and you'll find hundreds (if not more) possible causes and nearly the same # of fixes.
