Every headlamp has two adjusting set screws. One for vertical and horizontal. They are normally a torx driver socket that will turn these screws. If you have a garage use the garage door at night to set the beams reflecting off the door. Centering the truck to a center mark on the door would be helpful when you make the adjustments. That way your headlamps should aim evenly. Please note if your driveway is not level jack up the trucks rear end to make it so. Leveling the vehicle makes the difference before any adjustments are mad

  • Take it to a shop that has headlight aiming equipment. The adjuster compensates for level and uneven floors when setting up to aim your headlights. Doing it that way assures you won't be misaimed causing oncoming drivers to be blinded. Keeps the cops from ticketing you too.

How to adjust headlights.....1998 GMC


Open your hood. Look right above your headlights just inside the hood area, you'll see a small steel rod sticking up. To it's outside, against the fender is another one. They have tiny hex heads on them. Find a good fitting socket and adjust away. The fender side rod is in and out, the inside one is up/down.

I have a 2002 GMC sierra 4/4 and my torsion bar needs adjusted


i did mine on my 04 2500hd. first you have to jack it up by the frame to take the weight of the suspension, you should be on level ground, turn the bolts so they push up start with like 1 or turns on each then put the truck down and measure both sides and adjust until your height is where you want it and level on both sides. you might have to do it a few times until you get it where you want it. dont go to high or the ride will be rough

How can I adjust the headlights on my 2007 Fod


The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
