I had a similar problem on my 04 expedition. I just bought it and the headlights were aiming too far down. A rather larger gap was noticeable between the headlight and the hood. The so called adjustment bolt did nothing. I removed the headlights and found 2 issues. On the adjustment bolt there is a washer. Make sure when you re-install the headlight the washer sets on top of the plastic slot and is visible when looking down behind the headlight. Without the washer being in the correct location it will not tighten the headlight in place.
Second I found the adjustment bolt adjusted nothing. It merely tightened the headlight in place. What I had to do was to loosen this bolt and physically move the headlight into place and the re-tighten the bolt. Hence the slot is the adjustment. Turning the bolt CW or CCW did not move the headlight.
I tried several things trying to figure why the lights would not move until I realized I could move the light with my hands and tightened them in place using the adjustment bolt.

This may not be your issue but I found the owners manual instructions to be useless.

AIMING THE HEADLIGHTS
The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim and adjusted as necessary. Certain state and local authorities have requirements for headlight aiming; these should be checked before adjustment is made.

CAUTION About once a year, when the headlights are replaced or any time front end work is performed on your vehicle, the headlight should be accurately aimed by a reputable repair shop using the proper equipment. Headlights not properly aimed can make it virtually impossible to see and may blind other drivers on the road, possibly causing an accident. Note that the following procedure is a temporary fix, until you can take your vehicle to a repair shop for a proper adjustment.
Headlight adjustment may be temporarily made using a wall, as described below, or on the rear of another vehicle. When adjusted, the lights should not glare in oncoming car or truck windshields, nor should they illuminate the passenger compartment of vehicles driving in front of you. These adjustments are rough and should always be fine-tuned by a repair shop which is equipped with headlight aiming tools. Improper adjustments may be both dangerous and illegal.

For most of the vehicles covered by this guide, horizontal and vertical aiming of each sealed beam unit is provided by two adjusting screws which move the retaining ring and adjusting plate against the tension of a coil spring. There is no adjustment for focus; this is done during headlight manufacturing.


Because the composite headlight assembly is bolted into position, no adjustment should be necessary or possible. Some applications, however, may be bolted to an adjuster plate or may be retained by adjusting screws. If so, follow this procedure when adjusting the lights, BUT always have the adjustment checked by a reputable shop.
Before removing the headlight bulb or disturbing the headlamp in any way, note the current settings in order to ease headlight adjustment upon reassembly. If the high or low beam setting of the old lamp still works, this can be done using the wall of a garage or a building:

Park the vehicle on a level surface, with the fuel tank about 1 / 2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall.

If aiming is to be performed outdoors, it is advisable to wait until dusk in order to properly see the headlight beams on the wall. If done in a garage, darken the area around the wall as much as possible by closing shades or hanging cloth over the windows. Turn the headlights ON and mark the wall at the center of each light's low beam, then switch on the brights and mark the center of each light's high beam. A short length of masking tape which is visible from the front of the vehicle may be used. Although marking all four positions is advisable, marking one position from each light should be sufficient.

If neither beam on one side is working, and if another like-sized vehicle is available, park the second one in the exact spot where the vehicle was and mark the beams using the same-side light. Then switch the vehicles so the one to be aimed is back in the original spot. It must be parked no closer to or farther away from the wall than the second vehicle. Perform any necessary repairs, but make sure the vehicle is not moved, or is returned to the exact spot from which the lights were marked. Turn the headlights ON and adjust the beams to match the marks on the wall. Have the headlight adjustment checked as soon as possible by a reputable repair shop.
Hope helped with this (remember rated this help) Good luck.

On the upper grill side of the headlight assy. there
should be 1 or 2 push pins that hold the seal on the
headlight assy to the front of the fender. Also check
for a guide/push pin on the inner top of the assy on
the outer fender side. That should be all there is to
hold the headlight in place. Hope this helps.
