How do you remove old and install new rear bumper on a 2005 Mazda 3 sedan?

To remove the old rear bumper on a 2005 Mazda 3 sedan, begin by opening the trunk and removing any fasteners securing the bumper cover, typically located in the trunk area and under the rear lights. Next, unscrew any bolts or clips along the underside and sides of the bumper. Once all fasteners are removed, gently pull the bumper away from the car. To install the new bumper, align it with the mounting points, secure it with the previously removed fasteners, and ensure everything is tightened properly.
