How To Replace Headlight Housing 2000-06 Chevy Tahoe

All right. There's these little retainers right here. Slide these out and slide these straight up. You can grab the light assembly, slide straight forward. Disconnect the connector right here. There's two tabs. Just slide up on the two tabs and then the connector comes out. And same with this one. And there you go. Now with the new light assembly, these are test bulbs so you want to take these out. Replace the bulbs. Twist this to the left, slide it out. And this bulb is HB4U. Slide this in position. Same with this one. This is the high beam. Twist to the left. Slide it out. This bulb is an HB3U. And twist it to the right and you can line it up with the plugs, connect the bulb, and connect the high beam bulb. Just line this up. And take the pins. Get both pins started first. All right. Push the pins, lock them in place. After you're done, you're going to want to make the adjustments. There's an adjuster right here. This one is going to move the headlight sideways left to right and then to go up and down you're going to go down here. You're going to use a E8 socket. It's like a star. You can go down there, and if you don't have an E8 socket, you can actually just use a 1/4-inch socket. That'll work as well. And adjust accordingly.

This is going to be a general tutorial on how to aim your brand new TRQ headlamp assemblies. Okay. So looking at your brand new TRQ headlamp assembly, you're going to see where your low beam is, and you'll see a little dot right in the center. And that is the access point, okay? So what we're going to do is we're going to mark that with an erasable marker just so it's easier to see. Next, what we need to do is measure from the level ground up to this point and take note of that measurement. Now we're just going to pull the car up to our wall. On our vehicle, we remember that the measurement was 28 inches for our access point. Your vehicle may be different, but that's where I'm going to put this tape, just above that 28 inches. We'll do the same on the other side. Okay. So let's just back the vehicle up straight back 25 feet from the wall. And now that we moved our vehicle 25 feet back from the wall, we're going to start with our measurement here. That's where the headlamp center is. We're gonna go down 4 inches on the driver side. On the passenger side, we have our line here. What we need to do is go down 2 inches. To adjust the driver side, we're going to cover our passenger side headlamp. If you look at the backside of your headlamp assembly, you're going to see something that looks like this. This is the adjustment. Some of these headlight assemblies have one, two, or even more of them, but you should at least have one. This is how we're going to adjust the headlight beam. Now we're going to lower the top part of the beam down to just below this line. When you turn the adjustment to the right, it brings the beam up, and if you turn it to the left, it'll bring the headlight beam down. And this is this way on most vehicles. Let's continue on to doing the passenger side. All right. We properly aligned our TRQ headlamp assemblies. Okay. And on the quality TRQ headlamps for a pickup truck, the procedure is going to be the same. You're going to find your center dot, mark it, and then you'll measure from the level ground up to your dot.

So once your headlamps are properly adjusted, it'll be time to adjust your fog lamps. You'll notice on the driver side, the focal point is all the way at the bottom right now. I would like to bring it up so it meets up with approximately the bottom of the focal point of the headlight. Some fog lamps have an adjuster, others don't. The ones that do have an adjuster, you would just turn the adjustment to the left or to the right to adjust the beam up and down to where it needs to be. Now with your TRQ headlamps and fog lamps properly aligned, you can drive down the road safely.
