I have a 95 town car whose rear air shocks started leaking and not keeping the rear of the car up. Estimates to repair ranged from $1500 to $2500, as the shop (that I didn't trust much) said the computer that controls it needed to be replaced, and maybe the compressor...they wouldn't know until they replaced the non-refundable computer.
Instead I did web searches and found a vendor who sold me regular springs and shocks to replace the air bag suspension. I don't remember the exact cost, I think parts plus paying the shop to install them came to around $600 total. You can probably save a couple hundred if you make the swap yourself.
It took me about 5 miles of driving to "get used to" the different ride. 20,000 miles later and I'm still very pleased with the choice to dump the air suspension and go over to essentally what's in Crown Victorias (which are based on the same general platform.)
If you want/need me to look up who I got the kit from contact me off-list via email.

You can troubleshoot the rear air suspension of your 1990 Lincoln Town Car with a diagnostic tester. Most Lincoln dealerships have diagnostic testers.

Yes, it is.

Look under the rear of the car and you will see it.

you do mean shocks and not airbags right? well, you change shocks on the rear just like any other car with them but on a Lincoln the best way is to have the car resting all the way down,"with the airbag switch off". place a jack directly on the rearend and raise the vehical a little to release tension off the bolts. it's easier to put them on this way cause when you buy new shocks they are already compressed and its hard to pull or extend a compressed shock.
