Plastic Clip Remover Tool or Pliers, 8mm and 10mm Socket, 3/8 Ratchet, Socket Extension
Step 1: Remove the two clips circled in yellow and labeled as “1” and “2” inside the front fender well. Remove these clips from both sides.
Step 2: Remove the 10mm screw circled in yellow. Remove this 10mm bolt from both sides.
Step 3: Remove last hidden screw on both sides. The screw is hidden behind the fender liner in the wheel well. Fold the fender liner back to reveal a 8mm screw. Remove the 8mm screw. It is located between the lining of your car’s fender and bumper.
(Pro tip: turning the steering in the opposite direction will give you more room to work.)
Step 4: Remove remove the metal holding clip that secures the bumper to the fender.
You must pull the pins off of the metal clip first before removing it. There is one metal clip in each front wheel well.
Step 5: loosen the plastic floating bumper holder holding the front bumper to the truck’s body. Loosen the 8mm screw to slide the bumper off.
Step 6: Loosen the four 8mm screws from the top of your grille. Additionally, you might need to remove six clips attached to the bottom of the bumper (pointed out by the arrows) if you have the under-body plastic or armor.
Step 7: Remove all connectors and slide bumper off of truck. In our case, we had a temp sensor attached and had to disconnect it before removing the bumper.
Step 8: Remove two 8mm screws on top of the headlight by loosening them with an 8mm socket.
Step 9: You will now be able to see the last 8mm screw that needs to be removed before you can remove your headlights. Repeat for both sides.
Step 10: With all the three headlight mounting screws removed, you will be able to remove your headlights from your car. When removing your headlights, please be mindful of where the electrical connections are and carefully unplug them.
Step 11: Enjoy the new look!
