Ford Expedition 2007 4x4

Expedition 4x4, clean body with no scratches except near the driver's door; the trunk door has minor dents. There is an issue with the engine timing gears and a problem with the 4x4 locking mechanism (this is what I generally know about it). The vehicle is fully loaded, 4x4, the trunk opens electrically, the air suspension system was replaced with coil springs, but I converted it back to air, noting that the original system is still present, I did not remove it. The car has been inspected and renewed.
