    "Service Air Suspension" - message from dashboard
    Would it cost less to replace the air suspension with the springs?

      Not that big a difference in price, definitely cheaper by a few hundred but more importantly, your Hummer will ride differently and will no longer be "original". Maybe that don't matter to you though. Some people it does. It will be easier and is a one day job to install the springs and skip fixing the air suspension. You will always have the warning message displayed also. The fix for the air suspension could just be replacing the rear air springs but I did an '04 about 3 years ago and had to replace both rear air springs, the compressor and the control module. The repair bill was $2000

      Check out the many on-line auto parts sources; such as - or - to list just two sources - for the replacement parts, such as the suspension bushings.

    What causes the suspension to shake at about 50mph

      If you are saying that your mph begins to decrease at the same time the shaking begins, then your cause might be a frozen front brake caliper, but this would almost always cause a pull to one side or the other. If it is just shaking and you are not 100% sure as to whether the speed is really being affected, then try rotating the tires front to back and see if the shaking goes away. Check the front end components for looseness also.

      what happens is your computer sets a fault in the air compressor control unit and usually disables compressor operation until the code is cleared with a scanner or by running its self tests without any faults (could take 40 to 60 tests before the code will clear itself)the fastest way is to have the codes cleared to see if it functions normally afterwards.Also try to locate the compressor relay im unsure on this vehicle where it is at but if you can locate it try tapping on it and see if the compresor runs as your old compressor may have fried the relay.

    Why does the rear of my truck keep going down instead of leveling off like it use to when its parked?
    I have 121,000 miles on my vehicle. One morning I got up and the rear of the vehicle was sitting down. It looked like I had 2 flat tires on the rear of the vehicle. When I got in the vehicle and started it up, let it idle for a little while the rear end ...

      Have to check the suspension module for fault codes. I just got done with an 04 H2. Had fault codes and suspension error message. I am ver familiar with this system so if you can get someone to read the fault codes I can help. But I will tell you now that the pumps do go bad and if you have to replace the pump aka the air suspension air pump you then also have to buy a new air suspension control module that does not come with the new pump, even though the air suspension pump costs about $900. The module is another $290 about. Cannot say whats going on (nobody can for that matter) until codes are pulled. Standard cheap code readers cannot access it, only the professional shop grade $2000 scanners can like my OTCGenisys. I doubt they did anything intentional.
