There is a white ...screw/knob/whatever you call it on top of the headlight assembly. You turn it to raise or lower the beam. Best to do this against a garage or a wall of some sort so you get an even line. You can use pliers to twist it, just be careful not to break it off.

tblazed's Headlight Aiming Post

Here's a link to a great post by tblazed that shows a graphic representation of how to adjust your headlights.

I printed it out on May 9, 2009 because I needed to adjust my headlights after the McMeister Lift was installed. Good thing I kept it because I did a search, but it didn't show up in the list. So I guess I can't give you a raspberry about using the search feature. Go figure. (Aw, what the heck - :raspberry).

Beam Problem

Adjusting the headlamp is not my problem, it seems to be the beam on the drivers side has a different shape than on the passenger side. I was wondering if there is a different type replacement bulb? I adjusted the beams as even as I could. The high beams were exact but the low beams just don't look the same. The drivers side shines in peoples rear view mirrors and I know it is annoying them. I readjusted so it is not shining in peoples mirrors but the high beams are way off. The drivers high beam is almost useless now. Any suggestions??? :bonk:

The reflectors in the headlight assemblies are shaped differently on the left and right sides. Make sure the bulbs are in correctly and aim the lows. The highs should be correct.:m2:
