The 1997-2002 Ford Expedition 2WD is built with the following suspension components:
1997-2002 Ford Expedition 2WD Air Springs (x2)- commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. 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.
1997-2002 Ford Expedition 2WD Coil Springs (x2)- Coil springs hold the vehicle up but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change air shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocks.
1997-2002 Ford Expedition 2WD Rear Gas Shocks (x2)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.; the air spring assembled on top of the strut is commonly referred to as an air strut.
1997-2002 Ford Expedition 2WD Air Lines- tubes that run from a compressor (air suspension) to the air struts which carry pressurized air to the air bags components in order to adjust the height of the vehicle, respectively.
1997-2002 Ford Expedition 2WD Solenoids (x4)- This vehicle is equipped with 4 solenoids. These plastic components connect the electrical connection and lines of suspension components to the suspension control module. The solenoids are responsible for regulating the air pressure in each air spring or air shock. Solenoids are a small piece of the suspension system but they play a big role in how well it functions. If a solenoid is not working properly, it will cause the vehicle to be unlevel and, in turn, cause the compressor to burn out.
1997-2002 Ford Expedition 2WD Compressor- This vehicle is equipped with one air suspension compressor. The compressor is responsible for pumping up the air springs and shocks. When the air suspension starts leaking, the compressor is forced to run continuously to try and keep the air springs inflated. After a couple of days of running non-stop, the compressor will burn itself out. Replacing the compressor is a timely and expensive project to undertake.
1997-2002 Ford Expedition 2WD Dryer Assembly- This vehicle is equipped with a dryer assembly. The dryer assembly is responsible for getting moisture out of the air lines. Once the air suspension parts start to leak, moisture will build up throughout the air system. Moisture damages the air suspension components from the inside out. The dryer must be replaced whenever the compressor is replaced to prevent further damage.
1997-2002 Ford Expedition 2WD Suspension Control Module- This vehicle is equipped with a 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.
1997-2002 Ford Expedition 2WD 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
Proper diagnosis of a failed or leaking air suspension system is key in order to avoid total failure of the 1997-2002 Ford Expedition. Look for these common signs that the air suspension system is going bad, before it‚Äôs too late. The most noticeable sign that the air suspension system is failing is a major difference in ride height from the front to the rear end of the Expedition. Typically, with this model, the rear suspension fails first causing that end to sag. The front end will likely remain inflated. This gives the illusion that the Expedition is ‚Äúsquatting‚Äù down in an unusual fashion. One obvious sign of suspension failure is an illuminated suspension warning light on the interior instrument cluster. The condition of the air compressor can indicate a suspension problem, as well. If it has stopped working or is running too long (longer than 15-20 seconds at a time), then a suspension repair or replacement is likely needed. Any visible cracks in the rear air springs (caused by dry rot) further prove the suspension has gone bad.
OEM Replacement Cost
+ Front Air Springs ($837/air spring)
+ Rear Shocks ($253/air shock)
+ Coil Spring ($189)
+ Compressor and Dryer Assembly ($720)
= TOTAL: Over $2,820 (and that doesnt even include replacing electronic components that are known to fail such as the height sensors).
