You can get a Ford tool at most auto parts stores for about $8, makes it easier.
But a 4mm or 1/4" socket should work, might be 5/16th?
You need a tape measure and some masking tape.
Measure from the ground up to the
center of the light, write it down
Measure from the center of the Ford emblem(center of vehicle) to the
center of the light, write it down
Hopefully both lights are the same height and distance from center of vehicle, if not, then adjusting the headlights is the least of your concerns, lol.
You need a level drive way or parking lot with a wall at least as high as the head lights.
You need to park vehicle so head lights are 25ft from this wall.
Put a horizontal piece of tape on the wall 2" LOWER than the height of the headlights, use the bottom line on the tape as the marker.
Put a piece of tape vertically on the wall where you think the center of the vehicle is.
Go behind the vehicle and look if you guessed right
, if not move it.
You can also measure from each head light to the center marker, if they are equal then it is the center.
Now measure out from center tape marker and put another vertical tape line at each headlight location, from when you measured it above and wrote it down
.
The wall should look something like this now:
---[-----l-----]---
Turn on the head lights, of course dusk or night will make this easier
Beams should be dead center on the vertical markers on each side
And the top of the beam should be at the bottom of horizontal tape line.
I often lower the drivers side beam slightly so I don't blind other drivers if I have a heavy load, but up to you.
These are single lens setups so high beam should be fine once low beams are setup.
If you installed a 6" lift on the truck you may want to drop down the beams another 3" or 4"
, but up that high you often can't hear the cursing of oncoming drivers when they pass by, if you can then.............get a subwoofer
