when air shocks collapse on a navigator its an indication that one of the air bags are bad (dry rot). once one bag is bad the leveling system automatically lowers the other. i have changed many air bags on lincolns and i must say that they last a vey long time, ussually dry rotting between 8-10 years. however i would suggest changing them both. there are other possibilities leaky line, bad shut off valve, etc. these are rarely the problem. 95% of the time its the airshock (airbag) itself.

Call every local shops in your area for estimates.
A 1988 Lincoln Towncar has shocks in the front.
youre automatic air ride suspension went out it happens to alot of navigators/expeditions that came from the factory with rear air ride shocks
You have to replace with springs and shocks
Bad shocks

If you have figured out where it is leaking from then here is a link to check out. I haven't used these people yet, but I am planning on it if I need to replace the air shocks in the front...
I have a 2001 navigator. Been towing with it for over four years. I pull a 5500lbs trailer and never had a problem with the air bags. When I put the tongue weight on the hitch, the air bags pump the truck back up perfect.

Bad shocks, ball joints bad, tires out of balance. More then likely shocks.
