Bed Wheelhouse

The rear wheel housing, also known as the rear wheel well or is the area in the body of a pickup truck that surrounds and encloses the rear wheels. It is located on both sides of the vehicle, behind the rear doors or cab, and in front of the truck bed.

Here are some key aspects of the rear wheel housing:

1. Structure and Protection: The rear wheel housing serves as a structural component that provides support and rigidity to the vehicle's body. It helps maintain the proper alignment and positioning of the rear wheels. Additionally, it acts as a protective barrier, preventing road debris, dirt, and water from directly contacting the wheels and other components in the wheel well area.

2. Wheel Clearance: The rear wheel housing is designed to accommodate the size and movement of the rear wheels, allowing them to rotate freely without rubbing against the body of the truck. It provides adequate clearance for the suspension system, axle, and other associated components.

3. Aesthetic and Styling: The rear wheel housing contributes to the overall design and appearance of the pickup truck. It can be contoured and shaped to complement the truck's exterior styling and create a cohesive look between the cab and the truck bed.

4. Mud Flaps or Splash Guards: In some cases, rear wheel housings may have integrated or attached mud flaps or splash guards. These accessories help reduce the amount of dirt, mud, and water kicked up by the rotating rear wheels, keeping the vehicle cleaner and protecting the body from damage caused by debris.

5. Customization: Some truck owners may choose to modify or customize the rear wheel housing to achieve a specific look or accommodate larger wheels and tires. These modifications can involve widening the wheel well openings or installing aftermarket fender flares for a more aggressive appearance.

The rear wheel housing plays a vital role in ensuring the proper functioning, protection, and aesthetics of a pickup truck. Its design and construction can vary depending on the specific truck model, make, and year, as well as the desired functionality and style. Typically the rear wheel housing of a pickup truck is made up of an inner section and an outer section. The outer section is the piece that's often sat upon when taking a ride in the bed of the truck. If you put your knuckles directly on top of the rear wheel and then lift your hand upward you'll be touching the inner wheel housing.

The terms wheelhouse, wheel housing, wheel house, and wheel well are virtually interchangeable.
