only the front air bags leak, and only sometimes?
where is the release valve and could that be the prob? it is only the front and I heard a motor of some kind come on yesterday and then it went down.
Loriandrick, The most probable source for the leak would be your rubber air springs. Just like rubber tires and rubber hoses, they have a finite life and should be replaced with new rubber air springs. New air springs can be had for about $125 each delivered and as low as $290 for a complete set.
