this a job for the suspension professionals
there are coil springs with the air bags already inside the coils that will fit straight in
the thing with air bags is that if inflated to the correct pressure , the height of the springs will not vary as the load is taken by the air bag and not the coil spring
for example heavy vehicles running on air bag suspension retains the same ride height regardless of the load on the vehicle
what you propose is great for towing trailers, caravans etc or carrying heavy loads on the tray at the back
If the bag hasnt completely failed (punctured or worn to leaking) they can come "unseated" from the base at the bottom of the "bellow" or bag. Not very common but possible. Alternatives to dealer parts and installation checkout ARNOTT air springs. The bag alone runs about $100. If you can afford it replace both fronts with the ARNOTT new generation one piece airspring. The are easy to install and offer little or no headache. Lastly, if you are a fan of the unsurpassed comfort of your Range Rover air-ride suspension, dont let anyone talk you into the coil spring conversion. Its not the same level of comfort and you will feel a big difference in handling. Good luck!
Not really. The air bags act as replacement or extra coil springs to hold the car up. You might be able to replace them with coil springs from a Crown Vic. That may cause problems with the front air bags and the rest of the system.
The answer to your question is yes. They do sell a replacement springs for that vehicle.You may have air bags on the rear that appear to be leaking down you might check the air lines for leaks but most the time its the bags themselves that are leaking. This could get expensive replacing the bags the alternative to this is take them out and install coil springs with shocks. They sell the replacement conversion springs to your vehicle in a set the shocks will have to be purchased seperately. I did this to a lincoln town car for a customer of mine worked out well and didnt even notice a difference in the ride. Instructions will come with it and how to disable the wire so that the air suspension light will not come on.
Replacing the air bags is only cheaper if that is the only problem with the vehicle (which it hardly ever is). The air bags or other parts will act like a house of cards and over work your compressor and other components within the air ride system. Converting over to coil springs is definately the way to go.. eventhough I hardly ever recommend finding safety and suspension parts at a junk yard. Springs are easy to cut corners and costs on and a cheap spring can cause catastophic results. http://www.strutmasters.com offers affordable conversion kits and provides a lifetime warranty on all the kits they sell. The springs are only made of powder coated, American made steel coils that are designed to last the lifetime of the vehicle (unlike those airbags and compressor) http://www.strutmasters.com/lincoln-town-car-suspension-s/37.htm there is a direct link if it helps anybody having these problems. There are less expensive versions out there, but you get what you pay for.
Air suspension is controlled by the compressor in your engine compartment. The compressor runs when the suspension is not level. Either because you have loaded the car with exceptional weight and the system is now adjusting the ride, or you have a leak in the system, or you have a bad sensor.
If you have a leak, the most likely culprit are the air suspension bags, the air suspension solenoids or possibly the lines to them.

I don't work for either of them. I own a 96 TC and have replaced my air suspension with coil springs form Strutmasters. Work GREAT and I have no more air suspension problems. Rides just as good too. You can't tell the difference.
my brother in law replaced the air springs on my '94 town car with rear coil springs from a '92 crown vic. He raised the rear tires off the ground and put jack stands on the frame for safety on both sides. Then disconnected the shocks at the lower end and removed the air springs.removed rear tires and used a piece of 2x4 to pry axle down to provide clearance to put coil springs in place. then hooked shocks back up and it worked fine. the only way the coil springs could come out is if the car was upside down and then who cares. This project only cost $ 25.00 Real cheap being we were broke!
I have a 2002 Bravada w/air suspension. When the compressor is loud it is bad. I bought a new one for less than $300 off the net but after 6 months it is not inflating the rear even though it runs briefly after start-up. It is most likely the compressor check valve. The Compressor Service Kit costs about $25 at the dealership. My rear air springs went bad (right side first) with cracked rubber and leaking. The right side was always lower when it would inflate and would leak until the whole rear was down. New air springs are about $85 w/o shipping @ GMPartsDirect.com. Also, the sensor can go bad but my buddy who works on Bravada/Envoy said this is usually NOT the problem. Compressors go bad after a few years and the air spring rubber deteriorates causing leakage. If the air springs leak, the compressor runs alot more and wears out faster. I'm not a certified mechanic, but have replaced the compressor myself and it took about 2 hours. As for the Compressor Service Kit instructions- you can search "Bravada Letting You Down?" on the net and a tech gives full instructions on how to service the compressor. He states that the compressor check valve sticks and it will not build pressure to inflate the rear of the vehicle.
