The shocks on the Town car are actually regular shocks front and rear and are separate from the air springs. They are fairly inexpensive. The rear has air springs rather than mechanical steel springs. Do not mess with them if they are working. Replacement air springs can be purchased from http://www.arnottindustries.com/ for around $100 each and they will last for another 10 years. If you can change spark plugs you can change an air spring. Arnott gives detailed instructions. Don't be afraid of the air suspension, it is much superior over the steel springs.
Because they've gone soft and saggy.

The springs in the rear support the weight of the car, and give it a smooth ride along with the shocks.
Do a web search for strutmasters. They sell kit to remove rear air bags. I assume you need rear springs. They may sell front springs. I did rears and bought shocks. Only complaint car sit a little high in rear. Cost me $350 to have someone to install. Cheaper than air bags. Fran
No, the suspension needs springs, the shocks are there to damp the springs so the car does not bounce up and down after it hits a bump.
It keeps the body of the car from bouncing around. The springs help the car ride smooth.
The car will drive fine but the rear brake shoes may drag on the drum. This will quickly wear out the rear brake shoes, hurt you fuel mileage, and cause a loss of power. Replace the springs.
Auto parts stores sell a kit with springs and shocks that replaces the rear air bags with springs. Been there, done that.
It's easy.
We are in the middle of having it done to our 2000 Ford Taurus. The dealership gave us an estimate of $365.00 to change rear coil springs only. An independent shop that we trust told us they believe you should also change the rear struts in conjunction with changing the rear coil springs. He is charging us $419.00 to do all (we live in Michigan).
