Start by opening the hood. We are going to replace these headlights on this 2009 Suburban. It's got some cracking in there, and some just pitting and scratches and sun damage, so we're going to replace these with new headlights.

We'll start by loosening these 10mm bolts on top. These headlamps are held in with two bolts on the top, and one hidden bolt that's behind the bumper here.

So that we don't damage any of the paint on the bumper when we pull the headlight out, we're going to put some masking tape here.

So we're going to peel this splash shield back, so we can get up behind, into the screw, the lower bolt, that is holding on the headlight. It also will make it easier if you turn your wheel to the inside on whatever side you're working on, so you can open this up.

It’s held in with some 7mm self-tapping screws and some push clips. I'm going to start with the 7mm self-tapping screws. Using a flat bladed screwdriver, or trim clip tool, we're going to work these barbed clips out. Then fold this up.

So, with this splash shield pulled back, now you can see the lower screw that's holding in the headlamp. This screw down here is a 10mm, just like the top ones. The hole that it goes through in the headlamp is slotted in, open. So, I'm not going to totally remove it, I'm just going to loosen it just enough so that the tab, or the ear, on the end of the headlamp will be loose, and we can pull it off from the front. You don't have to go too much, I just want to make sure there's enough room for it to slide freely. That looks pretty good.

The next step is you have to pull the bumper off of this clip. There's a bracket in here that the plastic bumper snaps in to. You're going to grab the bumper, give it a good tug. Just like that. So now, with all these bolts loose, and the lower bolt loose, and this bumper spread down a little bit, we're going to pull the headlamp out. It's got two locating tabs here, and there's another clip-tab in the back that it's going to pull off of those, so you're going to have to wiggle it back and forth, maybe a little bit. This one came out pretty easy. Move the bumper around. With the headlamp out, you can see the electrical connector here. By pushing this lock and remove it.

We're working on the passenger side, but to remove the horn, it's identical on the driver side. We go down here, under this clip for the connector. Push it down and pull it away. Take a 10 mm socket and loosen the bolt holding the horn. Then you're going to reach in and grab the bolt because it's loose now, and lift the horn out of here.

To reinstall the horn, line up the locating tab into this hole and we've got our bolts. Take one hand and hold it up, and with the other hand place the bolt in the hole. Get it threaded in. With it started, switch back to my 10 mm socket and ratchet. Just kind of bring it down until it starts to get tight. Don't forget to connect your horn or else it won't work. There's tricky things in here to get started. It didn't give me a nice click with that seated. There it is.

When reinstalling the headlamp, this tab here needs to go into this bracket here. This tab under here, needs to go underneath this locating tab. These two locating tabs are going to fit in to the fender, here. It takes some maneuvering to get this in here.

I'm actually going to plug in the headlamp right now. Yeah, you just sort of got to maneuver it in there. Then just push on it a little bit, to get past the bumper grill. So now, as we're getting close here, we want to make sure we get these two tabs in to the fender. Then push in, that should lock it in the tab that's in the back, or bracket, rather. This lower tab has slid over the screw, so that's great.

Now I'm ready to reinstall these upper 10mm bolts. You might have to give the headlight a little push, to get it in position. I’ll use my 10mm socket. Just go until you feel these get tight. Finish off the top one. Now I'm going to tighten the lower bolt. It's up in here; it's a 10mm. I'm just going to make sure the headlamp was seated all the way in.

While you've got this bumper loose, now is a good time remove your masking tape. Now you can put the bumper back into the bracket. Just push it in until it clicks. Time to reinstall the splash shield. The barbed clips are going to go in first; just push those in. Take your 7mm bolts. I’ll switch to my ratchet. If you need to adjust the aim on this headlight, the adjuster's right here. It takes a 5 mm Allen Key. On the passenger side, the adjuster is in the same spot, but this is on the original headlamp. It's just a little bit different.
