Which component is typically part of a uniside?

A uniside refers to a vehicle structure that consists of the components on one side of the vehicle, typically combining several elements into a single assembly. In this context, the rocker panel is a critical part of a uniside because it runs along the lower side of the vehicle, connecting the front and rear sections. The rocker panel provides structural integrity, aids in the vehicle's overall strength, and can be essential for collision safety.

In contrast, the other components listed, such as the rear bumper, dashboard assembly, and wheel hub, either serve different functions or are located in areas of the vehicle that do not adhere to the definition of a uniside. The rear bumper is part of the end structure, not side-specific; the dashboard assembly is oriented towards the interior front of the vehicle; and the wheel hub is a component of the wheel assembly, relevant to wheel function rather than structural side formation. Therefore, the rocker panel is indeed the component that is typically part of a uniside.
