long-icon-xIs Your Suspension Failing? Ready to Order

How do I know if my 1986-1992 Cadillac Seville Air Suspension is failing?

Look for the following classic red flag indicators of a failed or leaking air suspension system on the 1986-1992 Cadillac Seville. Early diagnosis of a bad suspension is the key to avoiding total failure. An inability of the Seville to maintain the proper ride height is a bad sign. Any sudden height variance between different sides of the Seville should be further investigated. This may look like one sagging end, one inflated end, a squatting down appearance, or a shifting lean from one side to the other. If the air compressor stops working or runs too often, a bad suspension has likely put excess strain on it. In late-stage suspension failure, there will be an illuminated suspension warning light on the instrument cluster. The longer the Seville owner postpones a suspension repair, the more expensive it is.

long-icon-questionWhy Choose Strutmasters?Ready to Order

Why choose the Conversion Kit over replacing the air suspension system on your 1986-1992 Cadillac Seville?

The original air suspension system on the 1986-1992 Cadillac Seville is comprised of various parts that must always function in sync. If one part stops working, the system is defunct. Strutmasters' air to non-air suspension conversion kit eliminates this reliance for good. The kit, made in the USA, comes complete with two front strut assemblies, new mounts, and quality Eibach springs. The parts are more reliable than the originals and guaranteed by Strutmasters' Lifetime Limited Warranty. Each kit is accompanied by detailed instructions and online installation videos that help customers get it installed in about one hour per wheel. ASE certified experts are also available to provide tech support over the phone. Lastly, the cost of the kit is a fraction of the prices of dealership direct replacement and individual part replacement.

What kind of suspension does my 1986-1992 Cadillac Seville have?

The 1986-1992 Cadillac Seville is built with the following suspension components:

1986-1992 Cadillac Seville Shock Absorbers (x2)- a 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.

1986-1992 Cadillac Seville Electronic Air Struts (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.

1986-1992 Cadillac Seville 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.

1986-1992 Cadillac Seville 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.

1986-1992 Cadillac Seville Solenoids (x4)- 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.

1986-1992 Cadillac Seville Compressor- 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.

1986-1992 Cadillac Seville Dryer Assembly- used to keep moisture out of air lines and air springs in order to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build-up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced in order to eliminate the moisture and prevent any further damage.

1986-1992 Cadillac Seville Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

1986-1992 Cadillac Seville 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.

“Greetings,
Just purchased and installed your CAD-F1P complete strut conversion kit in my 1992 Cadillac Eldorado.Your salesman Mike was most helpful and I must say it solved my bottoming out and poor handling issues I had caused by my worn out stock units. The car sits higher in the front now just as it did when the car was new.

Thanks for supplying a great value priced replacement strut alternative.”
