    Yesterday I started the engine to exercise the leveling and other systems. After 5 minutes the rear wouldn't come up all the way and I started to hear a rhythmic air spitting noise from the tag axle area. turned out it was the main air dryer. Not the filter, which is only a year old and in fine condition, it was the spring mechanisms inside sticking, so instead of cleaning it bought a new one at a truck parts place here and installed the whole new one. $401.01 out the door and 45 minutes of greasy filthy yckkkk....Have replaced almost my entire air system. Only a few fittings to go.lol.
