The 2004-2007 Buick Rainier is built with the following rear suspension components:
2004-2007 Buick Rainier 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 factory air springs are the number one cause of all air suspension leaks. Since all air springs all 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.
2004-2007 Buick Rainier Shock Absorbers (x2) - has metal tubing filled with gas-charged hydraulic fluid that dampens vibration and reduces bounciness caused by travel on rough road surfaces. Some models dampening may be controlled by the suspension control module and can be very costly to replace.
2004-2007 Buick Rainier 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.
2004-2007 Buick Rainier 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.
2004-2007 Buick Rainier Solenoids (x2) - usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension 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.
2004-2007 Buick Rainier 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 air springs 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.
2004-2007 Buick Rainier Dryer- prevents moisture build-up inside of air suspension parts.
2004-2007 Buick Rainier Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle's correct ride height.
2004-2007 Buick Rainier 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 any of the following signs present themselves in the 2004-2007 Buick Rainier, a failed or leaking air suspension system is likely at fault. A visible indicator of improper ride height is a sudden uneven height difference between different sides of the Rainier. Often the rear end will drop from three to five iniches. This makes the Rainier look like it's ‚Äúsquatting‚Äù down in the rear. The air suspension system must be fixed promptly before other vehicle components wear out. For example, the air compressor may stop working. If the air compressor is running too often (it will be overly-noisy), a bad suspension may already be taking its toll. The final, and most obvious, symptom of a failed suspension system is an illuminated suspension warning light on the dashboard. Early diagnosis of a failed suspension is the key to avoiding total failure. At this point, it's time to carefully research the repair and replacement options available.
OEM Replacement Cost
'+ Air Springs ($200/air spring)
+ Compressor and Dryer Assembly ($500)
= Over $900 (but that doesn't include replacing electronic components that are known to fail such as the height sensors).
Aftermarket Replacement Cost
'+ Air Springs ($190/pair)
+ Compressor and Dryer Assembly ($500)
= Over $600 (but that doesn't include replacing electronic components that are known to fail such as the height sensors).
