I have a 2" leveling kit on my 2007 MegaCab Dually+ I am towing a 30' deck-over gooseneck all the time and when fully loaded (11,790KG) my headlights are always shining into oncoming traffic. I took the headlight assembly apart but there seems to onlybe a screw on the side for Left OR Right adjustment? Am I missing it?

Also, on the fog lights its totally opposite, you can adjust UP or DOWN, but not RIGHT or LEFT.

Any help would be greatly appreciated, Thanks guys!

 

STANDARD PROCEDURE
FRONT LAMP AIMING
VEHICLE PREPARATION FOR LAMP ALIGNMENT
1. Check for and correct any burnt out bulbs.
2. Repair or replace any inoperative, worn or damaged body or suspension components that could hinder proper
lamp alignment.
3. Verify proper tire inflation pressures.
4. Remove any accumulations of mud, snow or ice from the vehicle underbody and clean the front lamp lenses.
5. Verify that there is no load in the vehicle (cargo or passengers), except for the driver.
6. The fuel tank should be Full. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each estimated
gallon of missing fuel.
7. Verify correct vehicle suspension height.

The procedure that follows will prepare a suitable front lamp alignment screen.

1. Tape a line on a level floor 7.62 meters (25 feet) away from and parallel to the flat wall that will be used as the
lamp alignment screen. The level floor will be used as the horizontal zero reference.
2. An adjacent wall or floor member that is perpendicular to the alignment screen can be used as the vertical zero
reference. If there is no adjacent wall or floor member that is perpendicular to the screen, tape a second line on
the floor perpendicular to both the alignment screen and the first line, and outboard of either side of where the
vehicle will be positioned. This will be used as the vertical zero reference.
3. Position the vehicle so that the side of the vehicle is parallel to the vertical zero reference, and so that the front
of the lamp lenses are in the vertical plane of the parallel line taped on the floor 7.62 meters (25 feet) away from
the screen.
4. Rock the vehicle side-to-side three times to allow the suspension to stabilize.
5. Jounce the front suspension three times by pushing downward on the front bumper and releasing.
6. Measure the distance between the optical center of one of the lamps being aimed (head or fog) and the floor
(horizontal zero reference). Transfer this measurement to the alignment screen with a piece of tape placed horizontally
to the floor. This line will be used as the lamp horizontal reference.
7. Measure the distance between the vertical zero reference and the optical center of the nearest lamp being aimed
(head or fog). Transfer this measurement to the alignment screen with a piece of tape placed vertically across
the appropriate (head or fog) lamp horizontal reference. This is the centerline reference for the first lamp.

HEADLAMP ALIGNMENT
NOTE: Due to the linear nature of the headlamp cutoff, a properly aimed low beam headlamp will project the
top edge of the high intensity pattern even with the headlamp horizontal reference line on the alignment
screen. No horizontal (right/left) adjustment is required for this headlamp beam pattern. The high beam pattern
will be correct when the low beams are properly aimed.
1. Turn the headlamps On and select the Low beams.
2. Rotate the headlamp vertical adjustment screw
on the inboard side of each front lamp unit housing
to adjust the beam height as required.

FOG LAMP ALIGNMENT
NOTE: A properly aimed front fog lamp will project a pattern on the alignment screen 100 millimeters (4
inches) below the fog lamp centerline and straight ahead of the lamp.
1. Turn the fog lamps On.
2. Rotate the fog lamp vertical adjustment screw (2)
on each lamp to adjust the beam height as
required.
