01 4.4 lowers in rear overnight

Basically, the air suspension acts like it has a leak while I'm driving. The front drivers side drops lower and you can tell b/c the steering wheel becomes crooked and the DS dips. I also hear clunking, like its a sway bar link is loose on the DS, over bumps. If I raise up the suspension and start driving again, it levels off and the clunking noise goes away. Then after a few miles, it drops again on the DS and I hear the same noise. WEIRD.

Now it gets even more weird. I park the car in the garage for a few house and the whole car is leaning to the DS. Looks like a really fat person is sitting in the driver seat. Also when I get out of the car, I hear hissing like the front airshock has a leak (as its settling down). So now I'm convinced the front airshock is bad. BUT, then after I start the car up again and raise it to the full (topmost) rideheight, the leak magically seems to disapear and when I put the ride height back to the middle position, it DOESN'T leak anymore and I leave the car overnight and 24 hrs later, it doesn't even sag or lean. WTH? I also placed a floor jack under the DS front in case the car starts to sag again so I know if it is leaning. But guess what, it doesn't even touch the jack after 24hrs. What is going?! Is it a faulty airshock or is just a bad control unit? Seems really weird whats going on.

Any ideas?
I only have rear airbags on my 01 4.4- is there a common problem with those? When I open the door to get in, I hear the air pump start running and the rear end starts to go up- Any ideas??
Thanks,
T
