I was hoping someone might be able to offer some help to me. I have a '05 H2 SUT with the Adventure package. (Air ride etc.) I drove to work this morning and everything was fine. I went out to my driveway this evening to find my left rear is collapsed down with only about 4-5 inches clearance between the top of my tire and the fender well. The other 3 corners are fine. Is there any way to tell if it is a shock or an airbag? Is it safe to drive it like this? I noticed there is what looks like oil or grease around the lower part of the left rear shock. They're gas shocks though right? If so then is it possible to see a leak? I REALLY don't want to take it to the dealership ($$$) if it is something I can fix myself like the shocks. Any advice would be greatly appreciated. Thanks!
