Air Suspension Hissing - Please direct to correct thread

[shawnwilkins]

I have a 2004 H2 Victory Edition and have a love/hate relationship. At this point, gas is the cheapest thing about the vehicle. As with everyone else it seems, my air supsension only leaks sometimes and then all the time.

When I shut off the vehicle and get out I can hear the air coming out of the suspension like if you poked a hole in a tire. It is very loud and will leak all the way out sometimes and then others only for a second.

I have read that it might be the exhaust valve on the drivers rear behind the gas cap but it seems that I can hear it on both sides. Maybe it is just because it is so loud.

Thanks and I appreciate any help. At this point I am ready to fix the truck and sell it. It has already cost me about $4000 in repairs this year and only has 80,000 miles on it.
