I just leveled my '09 SCrew and think I need to adjust my headlights down a little. Is their a spec for headlight adjustment? If so, what is it? Second, how do I do it on an '09? Thanks in advance for your help.

 

I'm pretty sure the "pattern" and the adjustment screw location are in your owner's manual.

Personally, when I adjust mine, I just take the truck out to a deserted road at night and aim them down the right side of the road on low beam so they give me the best "view".

Try googling headlight aiming


Several links on this, all seem to say the same thing as the owners manual ( the steps to get to the aim are slightly different but have the same end results )

The aiming procedure starts on page 56 in your owners manual and includes the adjuster locations
