NIVOMAT shocks 2005 Yukon XL SLT- ride height?

[mountie]

With 142,000 miles, the truck seems fine, feels fine.... But what is the correct height measurement DIFFERENCE on front, COMPARED to the back? I want to see if the rear shocks are worn. ( Rear certainly not too low as shown in photo) When Nivomats fail, does the rear stay lower?

Put a few hundred pounds of stuff in the rear to make it sag, then drive it a block or two. If the Nivomats are working, the rear end should come back up to height.
