05 H2 SUT Air Suspension
 

Hello everyone-
What a great forum! First time posting so don't crucify me if I sound stupid. I woke up this morning and noticed my wife's 05 H2 SUT air suspension was completely deflated to the point that the rear wheel wells were about 2-3 inches from the top of the rear tires. This is the second time this has happened. The last time was a few weeks ago-so it doesn't seem to be deflating regularly. In order to re-inflate the bags, I had to start the truck, close the driver door and press the ride height control button on the dash. Has anyone had similar problems? If so what was the fix and costs involved? Thanks for your help!

Don't fix the air suspension convert it over to conventional coil springs. The cost and headaches with the air is not worth it you fix the problem now and soon something else with the air system will fail and it goes on and on.

Mine was doing the exact same thing it drove me nuts. One day down 5 days up. It was the air bags with small holes in them. Some days the bladder coverd the holes so it did not leak down and others it did not seal. It cost me 400.00 labor and bags.

Yes I agree. Changing it to conventional coils will do the trick.
