Major Problem

[realbrotha31]

I was driving around in my 2000 Navi and the rear end just drops slowly and doesnt come back up. Its like im driving a low rider or something. Very Bumpy ride its horrible. Like there is no air in the air bags or something.

You may have a leak in one or both of the air springs or a leak in the air line. A similar problem happened in my parents' 1999 Continental. It was an airline that time. You can verify if it is just a leaking spring by allowing the truck to achieve normal ride height, then shutting off the air suspension. If one side of the rear, or both leak down, then you have one or two leaking springs. It should be fairly easy to replace on your own. Replacement parts are available from the dealer or American Air suspension, which may have Ford parts for less. For the most part, Ford springs usually last the longest, so you have to see where you stand on the short term cost vs. long term durability scale. Best of luck!
