there should be 2 torx head screws, on either side of the upper headlight, one almost right below the headlight fixture (forgot the proper name, sorry) and one recessed much deeper into it. one controls up/down, one does sidewise. park in front of your garage door, maybe 25 feet away, and do it.
if you have OEM setup and your lights are pointing high, batcha your rear shocks are tired and rear end sagged.

dude, you sound sort of freacking out with that truck. all kinds of piddly stuff going. what did you buy it for?

 

Thanks, I'll give that a try in a bit.

You're right, I am pretty OCD sometimes.
But maybe you understand.. once you get a new toy, you just want to make it better any simple way you can. I guess I wouldn't consider myself as freaking out, but I admit I may be making big deals about nothing.

I bought this as a work truck really. After the purchase (about $16k), I went out and bought a Boss plow. I'm looking forward to a heavy winter. And also some hauling, but nothing major. I didn't intend on getting a flashy truck, but I saw this and loved it (plus it's an HD so that's probably better suited for the plow).

 

It works. I don't know why I didn't think to try that one..
Thanks.

 

because it did not look like an adjustment screw. i was amazed myself. GM has some sort of a fetish on torx bolts and nuts.
you welcome, glad it worked.
hey, out of kicks, find that long rod that lays flat on top of the headlight housing. then turn it towards you and pull up and out. the whole entire headlight comes out. sweet! so do marker/DRL lights below. very clever.

 

Haha yeah it's an interesting design.. My first post on this forum was regarding replacing the daytime lights.. I had trouble getting the bulb out so I asked for help. It's been so cold recently though I think I'll wait until spring to try again.

 

no need to. there's a white plastic clip on the side of DRL assembly. you just pry it with a flathead, and the whole piece comes out. you might need to flash some light into the gap to see it.
as of the main headlight assy, i found it by pure accident. i'm like Cramer - if there's a lever or a button, i'll pull or push it. so i was standing there staring at that rod and then just sort of yenked it out - and cought headlight right on time, as it popped out. so i learned.
what you'll find about this truck that it is ****ty made, but easy access to most of all. except the fuel tank, i've heard. oh, yeah, and theATF pan removal..... yeah, that was sweet dreams indeed.[] otherwise, as far as you have set of oversized wrenches and torx heads - u good.
