What kind of suspension does my 2001-2002 Mercury Grand Marquis have?

The 2001-2002 Mercury Grand Marquis is built with the following suspension components:

2001-2002 Mercury Grand Marquis 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.

2001-2002 Mercury Grand Marquis Shock Absorbers (x4) - 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.

2001-2002 Mercury Grand Marquis Coil Springs (x2) - the front of the town car already has coil springs, that’s why we not only offer replacements for weakened coil springs in the front, but our conversion kit puts the same, sturdy design on the rear of the vehicle.

2001-2002 Mercury Grand Marquis 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.

2001-2002 Mercury Grand Marquis 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.

2001-2002 Mercury Grand Marquis 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.

2001-2002 Mercury Grand Marquis 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.

2001-2002 Mercury Grand Marquis Dryer- prevents moisture build-up inside of air suspension parts.

2001-2002 Mercury Grand Marquis Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

2001-2002 Mercury Grand Marquis 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.

How Do I Know If My Air Suspension Is Failing?

The most common symptom of a leaking or failed air suspension is a sudden noticeable uneven height difference between different sides of the vehicle. The vehicle could have a sagging rear end or front end, it could lean to the left side or right side, or the entire vehicle could be squatting down lower than normal. Other symptoms could include a suspension warning message or light in the instrument cluster, or the air compressor no longer working or running way too often (which would be very noisy and noticeable). The last major tip is your vehicle is no longer able to reach or maintain the proper ride height.

Why choose the Conversion Kit over replacing the air suspension system on your 2001-2002 Mercury Grand Marquis?

We have already seen the assortment of parts that construct the air suspension system. Our conversion kit gets rid of having to depend on all of those parts functioning correctly and in sync. This conversion kit consists of (2) replacement coil springs for the front, and (2) Eibach coil springs to delete the air bags in the rear. The conversion not only saves you time and frustration, it saves you lots of money. Now let’s take a look at the cost difference between choosing an air vs. a non-air suspension system. Here, we are going to compare three prices: the price for repairing your air suspension system at the dealer, the price for installing aftermarket air suspension parts on your vehicle, and the price of getting rid of the faulty air ride heartache and installing a brand new coil spring suspension conversion kit:

What kind of suspension does my 1997-2002 Ford Expedition 4WD have?

The 1997-2002 Ford Expedition 4WD is built with the following suspension components:

1997-2002 Ford Expedition 4WD 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 4WD 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 4WD 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 4WD 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 4WD 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 4WD 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 4WD 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 4WD 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 4WD 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.

How Do I Know If My 1997-2002 Ford Expedition 4WD Air Suspension Is Failing?

There are a couple of distinctive things to check for when trying to diagnose whether or not the air suspension on your 1997-2002 Ford Expedition 4WD is failing or has failed. A clear sign of suspension failure is a difference in the height of the front and rear of the vehicle. Ordinarily with this vehicle, the rear will fail first causing the vehicle to look like it is squatting down in the rear. Another sign of a failing suspension is the suspension warning light on the instrument cluster. Another sign would be the air suspension compressor running too long (The compressor should never run more than 15-20 seconds) or not at all and visible cracks in the rear air springs caused by dry rot.
