Adjust Headlights on Suburban

How to adjust the headlights on a 1995 GMC Suburban

The headlight son my GMC Suburban were really foggy and yellow. I am sure I could have cleaned them and gotten new bulbs but I found a good deal on replacement assemblies so I just changed out the whole thing. The first time I drove i the dark however, I realized I needed to align the new headlights. It was not obvious to me how to do it.

You don’t have to remove the grill to adjust the lights but since I had it off anyway, I took a picture to make it more clear how to adjust them.

Fist of all, the two 4mm hex pins that look like adjusters, are not adjusters. They are the pins that hold the light in place. If you remove these pins you can pull the headlight to change a bulb or something. To change the whole housing like I did you have to remove the grill.

The adjusters are hidden deep behind the grill. They have a funky star head on the bolt but I was able to turn it with a 7mm socket. I had the right socket but it would not fit in the access hole. I used a long extension on my nut driver to reach the adjuster bolt.

See the pictures for more info.
