2001 lightning suspension question!
 

i recently purchased a 2001 ford lightning and the previous owner had airbags placed on the back of the truck, i prolly wouldnt want to replace it just yet but i realized that there is a slow leak so its bein annoying having to fill it up every 2-3 days and was just wondering what kind of a kit a person could buy to replace the whole system.

air bags are really only needed if its super low. How low are you?

we need more info

What kind of airbags are you talking about, like air suspension or helper airbags? I have Firestone airbags on the back of my Lightning for towing. Under normal driving, I have no air in them. When I tow my boat (4000-4500 lbs), I inflate them to keep the rear end from squatting.

First thing I would do is see where they are leaking from. Likely the leak is from 1) air air fitting, 2) air tube, or 3) the airbag itself. The fittings and tubes can easily be replaced. Once you get to a leaking airbag, it may just be cheaper to install a whole new set depending on the replacement cost.
