ISSUE
Some 2007-2009 Expedition and Navigators vehicles equipped with rear load leveling suspension, may exhibit air suspension leak down on one or both
rear corners after extended periods of time in temperatures of -22 degrees Fahrenheit (-30 degrees Celsius) or below. The leak down is the result of
premature wear of solenoid seat at low temperatures.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Determine that concern occurs at -22 degrees Fahrenheit (-30 degrees Celsius) or below, after sitting long periods of time, usually over night. If concern
does not occur under these conditions, do not continue with this procedure.
The concern may not be duplicated if the vehicle has been sitting inside for over 15 minutes. Replace the air spring solenoid valve per Workshop
Manual, Section 204-05: Vehicle Dynamic Suspension.
