2001 lincoln navigator suspension went out, vehicle is sitting low on rear tire

INSIDE THE WHEEL OPENING TUCKED INTO THE FRAME WHERE THE REARWARD CRADLE IS LOCATED BESIDE THE SUSPENSION AIRBAG

That is not a question you ask on the internet,
& no one has any diagrams, unless they own the
same vehicle & have purchased factory manuals

You ask a dealer by giving the parts dept your
VIN #

If your converting from air to conventional suspension,
then you ask the parts suppliers that sell the new parts
your going to use to replace the air shocks/struts

Time to trade it in.

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.

don live in the real world, that suspension is never going to work right again. you are going to spend a ton of money, and no matter what you do something else will go wrong. big mercs, lincolns, BMW, caddies, land rovers, etc all sit in the same saggy swamp. there are still thousands of collapsed Peugeots sitting in barns since the 1970s across the land waiting for a real suspension fix.

take a long look at www.strutmasters.com and consider junking the air or hydraulic suspension system and trading up to a real one with springs and shocks.

You must have a leak or its not pumping air like it should. This happened to my dads Lincoln towncar back in the day.

your truck comes with suspension airbag for a smooth right..all lincoln naviagator come with it..if your take it the shop and they forget to disable that before they lift it up..most likely they blown the airbag for your suspension...those air suspension are rear spring for your truck

it most likely blew a line going to the rear leveling valve to leval out the truck i would start there and then check the bags and the valve it self.

the auto leveling is standard on the navigator.
first you have to understan that the auto leveling system is on front and rear of these trucks.
one way to tell is do you hear the pump running and do you have air in the front bags. and if you do you need a rear level sensor.
later paul

do you have a auto leveling system?
