2001 Lincoln Navigator

These Lincoln air suspensions are terrible. I have converted many over to coil springs at a fraction of the cost of replacing/repairing the bags. If the rear bags don't inflate, there is a broken air line to the bags or the bags are leaking

Usually between the frame and the rear axles. A lever type device, should be fairly easy to locate. Check that the compressor is building air pressure and storage tank. Air bags not leaking and etc.

could just be a seal on the air line itself, or possibly a whole in the line or one of th eleveling air bags. gong thru the water should'nt have any effect on it,unfortunately these are just like any other part, or seal they just eventually wear out.

The air bags commonly go bad on these trucks as well as the Expeditions. They are called Air Springs. I sell better quality ones than those sold at auto part stores and they are also a bit cheaper than dealer parts. But either way the problem is you have bad air springs.

Your air bags are leaking and sounds like your air compressor doesn't work. Suspect new air bags and a new air compressor. And/Or ride height sensor located at the drivers side fender well above the controll arm.

my air bag went bad and the samething happend i changed the shockes and did away with the air it was cheaper

Sounds like your air ride suspension is either leaking air in the air bags, air lines,etc, or the compressor is not working. If your truck is still under warranty take it to the dealership to get it fixed or with a good mechanic. If it is an air bag or the compressor start checking online for any good, cheap parts because parts for this SUV run expensive.

The most common cause is the air suspension bags leaking, you will need to pressure test them and ID if one or both are leaking.
