Hi,
My '08 Yukon Denali has developed quite a bit of sagging in the rear suspension (1-2"). I'm a bit of a noob, but believe this trunk has air springs. I notice that I hear a pump run for a short while when the engine is run, but even with this it's sagging. Both sides appear to sag by around the same amount.
I've read about the need for new shocks, springs, blocks and more, but am not sure what the source problem is on this factory air suspension.
Any way to tell if it's the air springs or something else? Any suggestions of what to check?
