Before starting, park your vehicle on a flat surface and engage the parking brake. Wear safety gear and ensure the engine is off. Gather all tools and components to streamline the installation process.
Remove the Existing Bumper
Use your socket set and screwdrivers to detach the existing bumper. Carefully remove any bolts, screws, or clips holding it in place. Keep these fasteners in a safe place in case you need them later.
