I recently purchased a 2004 Rainier AWD with air suspension. This suspension seems to be rear hard and you can feel every asphalt strip you cross. Is there a relief value that could be stuck that would cause the air bags to be pressured up too much?

:tiphat Welcome :tiphat Have you checked the tire pressure? If the air ride is the problem, you would see the back-end a lot higher than the front.

The air ride system runs continuous diagnostics to see problems like that. If it isn't happy, it flashes the LED near the air inflator valve inside the rear cargo area as a clue. It's not often I hear of too-hard shocks, but that's another possible problem, but I agree it's likely tire pressure to check first.

Hi, did you find a solution, my 2006 envoy Denali has the same problem and will not come down.
Thanks,
Joe
