The 2003-2009 Hummer H2 is built with the following suspension components:
2003-2009 Hummer H2 Rear Air Springs (x2)- (models with air suspension only). Commonly referred to as air bags, a plastic and rubber bladder that uses pressurized air as a cushion to support the rear of the vehicle. The rubber air springs take the place of a traditional steel coil spring used on most other vehicles. Tiny cracks in the rubber portion of the air springs are the number one cause of all air suspension leaks. Since all air springs go bad at about the same rate, if one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time .
2003-2009 Hummer H2 Shock Absorbers (x4)- Metal tubes filled with gas-charged hydraulic fluid to control bouncing motion and dampen vibration caused by travel on rough road surfaces.
2003-2009 Hummer H2 Compressor Assembly- Creates and sends pressurized air to the air springs. When the air suspension starts leaking, the compressor (also known as an air pump, has to start working harder to try to keep the system inflated. By the time air suspension leaks down completely, the compressor has normally failed completely or damaged to where it can't keep the system at full PSI.
2003-2009 Hummer H2 Height Sensors (x4)- A linkage located near each wheel that constantly measures the height of the vehicle and reports this information back to the suspension control module. The ride height sensor is a moving part and eventually they wear out.
2003-2009 Hummer H2 Suspension Control Module- This vehicle is equipped with a computer known as the suspension control module. This module is the brain of the suspension system and it reads all of the signals that are being sent by the height sensors and determines if the vehicle needs to be raised or lowered.
2003-2009 Hummer H2 Rubber O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
Suspension Failure Signs
A sudden loss of three to five inches of ride height in the rear of the vehicle is the most obvious sign of trouble. Millions of up and down motions and dry rot due to age causes tiny cracks to form in the rubber portion of the rear air springs. This lets air leak out of the system on your 2003 to 2009 Hummer H2 and causes the vehicle's onboard compressor to run overtime. Eventually, once the cracks get large enough, the compressor can no longer keep up. When the compressor overheats and shuts down, the air springs deflate and drop the rear of the vehicle three or so inches. If this happens intermittently, it is probably due to the compressor shutting off to cool down. At some point, it will no longer be able to make enough air and full failure will be in effect. Another sign of trouble is an illuminated suspension warning light in the instrument cluster. Unfortunately, when any of these events occur, a big repair bill is right around the corner.
OEM Replacement Cost
+ Rubber Air Springs ($289/spring)
+ Air Compressor Assembly ($1363)
= TOTAL: Over $1941 (and that doesn't even include replacing electronic components that are known to fail such as the height sensors).
