Which element is not part of the front bumper assembly?

The front bumper assembly is designed primarily to protect a vehicle's front end during low-speed collisions, and it typically consists of several key components. Among these components are the impact absorbents, which help to reduce the force of a collision, the bumper cover that serves as the outer shell providing protection and aesthetic appeal, and the license plate bracket, which is often mounted to the bumper cover for proper display of the license plate.

Wheels, on the other hand, are not part of the front bumper assembly. They are considered separate components of a vehicle's drivetrain and suspension system, serving the essential function of enabling mobility and supporting the vehicle's weight. Thus, wheels have no direct connection to any aspect of the bumper assembly, confirming that they do not fit within the context of the elements that constitute the front bumper assembly.
