Why choose the Conversion Kit over replacing the air suspension system on your 2003-2004 Lincoln Navigator?

When your 2003-2004 Lincoln Navigator air suspension system goes bad, you want to know you are going to repair it once and repair it right. At Strutmasters, we are pleased to offer conversion kits with the highest quality parts available on the market. We are The Suspension Experts, and we know about the myriad parts that make up the faulty air suspension system in the Lincoln Navigator. THat’s why we created the kit- to eliminate the dependency on all those parts functioning properly and in sync in order for your ride to be safe and working on the road. The kit is a direct replacement and includes four completely pre-assembled coil-over struts that are fixed with as little as five bolts per strut in about one hour per wheel. The kit was made with our beloved DIYers in mind- watch our installation videos on our YouTube channel or ask our in-house technicians any questions about your bad Navigator suspension for extra support while getting the repair done.  The conversion kit is cost effective; it saves you lots of money on top of time and frustration. Let’s take a look at the price difference between replacing air suspension vs non-air suspension conversion kit. Now 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-over suspension conversion kit. You will soon see why many customers choose Strutmasters over dealer replacement.

long-icon-xIs Your Suspension Failing?

How do I know if my 2003-2004 Lincoln Navigator Air Suspension is failing?

You want to be aware of the common signs of a failed or leaking air suspension in your 2003-2004 Lincoln Navigator, in case you need to diagnose a bad suspension. The most obvious is a sudden and noticeable uneven difference in ride height between different sides of the Navigator. Sagging in the rear or front, one inflated side, leaning to the left or right side, or an overall appearance of the Navigator squatting down lower than usual are all indicators of suspension total failure. When this occurs, it’s common for the air compressor to cease working or run way too often (it will be loud and noisy). Other components may wear out. Your Navigator’s ride height should remain consistent. If it looks like it’s been “slammed” down to the ground, you know you need a repair. This situation is unsafe, and you can’t be on the road.

long-icon-gearVehicle Components

What kind of suspension does my 2003-2004 Lincoln Navigator have?

The 2003-2004 Lincoln Navigator is built with the following suspension components:



2003-2004 Lincoln Navigator Air Springs (x4)- 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.



2003-2004 Lincoln Navigator Struts (x4)- 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.



2003-2004 Lincoln Navigator Height Sensors (x4)- 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.



2003-2004 Lincoln Navigator 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.



2003-2004 Lincoln Navigator 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.



2003-2004 Lincoln Navigator 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.



2003-2004 Lincoln Navigator 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.



2003-2004 Lincoln Navigator Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.



2003-2004 Lincoln Navigator 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.

This is a nicely designed, high quality kit with Eibach springs – one of best made US brands. Installation was straight forward in terms of procedure, but I have some lessons learned as noted below. I have a 2004 Navigator in excellent condition. By all means, watch the Strutmaster YouTube install video.

I’m very satisfied with the ride height after install; if the springs settle a bit after time, will not be an issue. Ride character after install is pretty much same as with air springs – most drivers will feel no difference. Only the most discriminating will note a bit of harshness “at the margin”, ie, abrupt road surface roughness. I count myself as discriminating and am very satisfied with ride. Air springs are softer overall, but this set up is great.

Tools/materials I found useful are a 3/8” or preferably ½” ratcheting wrench with metric socket heads and a hollow tube handle extender bar, penetrating oil, an 18”-24” crow bar to lever the attachment point for the bottom end of the struts during install, a hammer, and of course jack stands for safety.

I found a 30mm socket head necessary for removal and install of the large bolt securing the bottom end of the strut, as well the hammer to pound this pin out and back in during removal and install. I found the 15mm socket head most useful for other bolt heads in the assembly. Most people don’t have the 30mm size head; despite have a great tool set, I did not have this large size and had to purchase it.

I recommend spraying the strut bottom end bolt head and nut with penetrating oil once removing the tires – let that sit for 15-30 min before unbolting, while doing other disassembly work. One of those bolts was particularly difficult to loosen and I struggled with it for some time. An impact wrench would have been useful; I banged on it with a hammer for a bit, which didn’t seem to help. In the end it was just brute force, and using a hollow tube handle extender. (An 18”-24” hollow tube to slip over the ratchet wrench handle, extending it and giving more leverage. Heavy gauge aluminum, steel or even a lead plumbing pipe will do.) My Navigator is a California car with mild weather elements; elsewhere that bolt assembly might have been more difficult.

The strut top end nuts have nylon locking rings, so are not hand turnable to a great extent. For the front shocks, I was able to reach down through the engine bay with about 12” of socket wrench extenders to make removal and install easier. For the rears, with very small working spaced, I had a swivel-head type ratchet wrench which made install easier – either way, securing those nuts took some time and patience.

I did the install as a two-person team and recommend it. Install was 3-1/2 hours start to finish for all 4 corners, including time to run out and purchase the 30mm socket head. We worked both left and right sides of the install in parallel, and helped each other with 4 hands when necessary – particularly when aligning the strut bottom end for install.

The above experience would have been useful for me in preparing for the work. I’m not a mechanic but have good mechanical aptitude. Luckily I have access to an extensive tool set – without that, the above notes would have been essential. Hope this helps future buyers.

Very happy with the Strutmaster kit. High quality components and fit. Great ride as replacement for air suspension. Will last a lifetime with no maintenance. Highly recommend it. And kudos to Strutmaster staff being knowledgeable, friendly and polite.
