Need to know what your question is.
A person can reset the air ride suspension on a Cadillac Deville by disconnecting the compressor wiring harness from the compressor itself. This is accomplished by putting the vehicle on ramps.
On a 1997 Ford Expedition : ( NO ) not on the front suspension It could have the REAR load levelling air suspension
It costs about 1,200 dollarsIt costs about 1,200 dollars
The air bags may need to be replaced. Check the air suspension switch and maybe the fuse that controls it.
The switch can be found under the dash on the passenger side of the vehicle, closest to the door.
One can find an air ride suspension specialist in San Diego on craigslist. AOS is a craigslist user who offers support as an air ride suspension specialist in San Diego.
So what is the question ?
Ebay
I think they have air ride shocks in the rear not the whole suspension.
Air ride compressor, air suspension compressor, and air pump are the names used for the same device. They are used to pump up the air suspension.
The Expedition can have the regular rear suspension...coil springs, shocks, etc or it could also have been equipped with air suspension. If yours is leaning to one side I'd bet you have air suspension and a bad air bag.
