Manual Air Removal
When compressed air enters the rear load leveling system, its only normal means of escape is through the electrically controlled air vent solenoid. To bleed air from the system manually, place a Schrader type tire valve on the air compressor. Remove the black plastic protective cap and depress the inner valve stem. When air is fully bled from the system, remove the air line from the dryer or air shocks by pushing down on the retainer and pulling the air line outward.
