Well, that bubling is certainly bad. But as noted -- often compressors are going sound when the get loud. But it might be just the rubber insulating grommets...
My front bags were leaking down slowly and the shocks were shot on all four corners. When I priced out all the parts for my 04 (same as yours), I realized that it was going to be cheaper to go to coils.
I have the shop manual for my 04. About 100 pages of diagnostic algorythms for the air suspension, much of which requires Fords own diagnotic tool (not just a code reader). The Ford tool allows the dealer to individually let down the air in a corner to check the solenoid (4 of them). etc etc....
I just decided that the LSS was not worth the trouble...
FWIW -- I bought a dryer and remanufactured pump from americanair about 6 weeks before the slow airbag leak started up front. Nice looking unit and much quieter, and ran less. So the original was likely dying (I replaced my compressor becuase it was loud and running a long time).
But as other posters note, it MIGHT just be the grommets, plus the leak you have already discovered.

I'm leaning toward getting the compressor/dryer from american air, I just hope the dryer leak was my only leak so I don't burn up that compressor too.
Thanks everyone for the help!

Certainly just about any leak can cause the compressor to run. Bear in mind, this is a small volume, high pressure pump. Its not made to pump lots of air, as it usually does not have lots of demands, just a little adjustment here and there.

This is worth a shot, but I can find the isolators on the American Suspension website??
