The 2002-2009 GMC Envoy is built with the following suspension components:
2002-2009 GMC Envoy Air Springs (x2)- commonly referred to as air bags, a plastic and rubber bag that uses pressurized air as a cushion to support the weight of the vehicle. These rubber air springs are the number one cause of all air suspension leaks. Since air springs go bad at about the same rate, if one is leaking, the other one will not be far behind. For a proper repair, all of them need to be replaced at the same time.
2002-2009 GMC Envoy Shock Absorbers (x2)- these control the wheel-to-ground contact for the rear of this vehicle. Shocks dampen vibration and bounciness caused by rough road conditions.
2002-2009 GMC Envoy Height Sensors (x2)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.
2002-2009 GMC Envoy Air Lines- tubes that run from a compressor to the air which carry pressurized air to the air bags in order to adjust the height of the vehicle, respectively.
2002-2009 GMC Envoy Solenoids (x2)- these plastic components work along with the control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.
Compressor Assembly- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.
2002-2009 GMC Envoy Dryer- prevents moisture build-up inside of air suspension parts.
2002-2009 GMC Envoy Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle's correct ride height.
2002-2009 GMC Envoy 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
If the 2002-2009 GMC Envoy is unable to reach and maintain its proper ride height, a failed or leaking air suspension system may be the cause. Look for the following common signs of a bad air suspension system, and resolve any issue before total failure sets in. Typically, the driver will notice a sudden three to five inch drop in the rear of the vehicle. Look for an illuminated suspension warning light on the dashboard. Lastly, check other vehicle components for signs that a bad suspension has caused them to wear out. The air compressor, for example, may have stopped working already. If it is running too often (noticeably noisy) then it may be in danger of wearing out soon. Any of these suspension problems should be fixed promptly. There are a variety of direct replacement and repair options available to resolve the issue.
OEM Replacement Cost
+ Rear Air Springs ($160/spring)
+ Rear Shocks ($80/shock)
+ Air Compressor Assembly ($420)
= TOTAL: Over $900 (and that still doesn't include replacing electronic components that are known to fail such as the height sensors).
Aftermarket Replacement Cost
'+ Air Compressor and Dryer Assembly ($110) + Rear Air Springs ($130/spring) + Rear Shocks ($40/shock) = TOTAL: Over $450 (and that still doesn't include replacing electronic components that are known to fail such as the height sensors).
The assorted parts that make up the air suspension system on the 2002-2009 GMC Envoy must always remain in sync. When one part stops functioning, the system is defunct. As The Suspension Experts, we knew there had to be a more affordable and better quality alternative to direct replacement at the GMC dealership. The Strutmasters air to non-air suspension conversion kit, made in the USA, includes two cold-wound steel coil springs and two shocks for the rear end of the Envoy. DIYers love that the kit is installed in about one hour per wheel. Designed to save time and frustration, each kit includes detailed installation instructions. ASE certified technicians are available to answer questions about the repair, from start to finish. Installation videos are available to view online, too. The customer service is top-notch, but the low price is what convinces most of our customers to make the switch from an air to a non-air suspension system. Review the difference between the following three prices: that of repairing the air suspension system with Original Equipment parts at the GMC dealer; that of installing aftermarket air suspension replacement parts piece-by-piece; and that of eliminating the air suspension headaches for good by installing the Strutmasters rear suspension conversion kit.
