Default truck problem please help quickly

i have a 97 ford expedition with about 120,000 miles and today when i went out i found that the back was way down like a lowrider wheels almost rubbing the wheel well, so i took it for a drive thinking that it was just the airsuspension not leveling, after driving i found that only the frint air suspension will work and when in park the frint would raise and when driving the front will lower to even out with the back?? wtf is wrong does it have a rear compressor or what could be the problem?

there is an air line union that connects the air line from the compresor to the air line going to rear air suspension that likes to break. it is located under the brake master cylinder. part is like 1 in long and is hard plastic with a quick coupler at each end. sometimes the lines come completely disconnected. this always makes the rear bags deflate. check that, part is like $30 from a dealer.

just have to ask... is the automatic leveling suspension switched on? it would display a yellow "ck suspension" light on dash.

I agree with onebadragtop. I work for ford and replace those unions by the truck load.
