I went to run an errand today and as I pulled into the driveway the trailer hitch touched the concrete. It ain't supposed to do that, and I was pretty sure I knew what was wrong. I checked, and yep, one airbag on the driver's side has blown out. I only use them for load leveling and normally run with about 4 or 5 psi in them unless there is a load, and I can pump them to 20 pounds.
They seem to pop in single sides. I bought a new pair years ago, and now I get to put the other one on. Oh joy. The good news is it is pretty simple with the lift. Remove the shock bolt on the bottom, let the trailing arm drop, and remove the spring. The air bag is inside the spring.
The car came with air shocks. Those would last about 12 months, and needed to be replaced. They were "lifetime" guaranteed, so the new ones were free, but just the time to replace them. And they were crappy shocks. So I replaced them with Bilstiens front and back, and installed the air bags. With air bags it is imperative to use Bilstiens, or the rear end rides like a pogo stick. It just keeps bouncing. Good shocks, no issue. The Bilstiens have been on there for a long time.
