Purpose and Vehicle Placement

The wheel hub assembly with strut, caliper, and disc is intended for installation on the rear right side of the suspension. It is a key node where elements responsible for the following are connected:

• wheel guidance relative to the body,
• transfer of vertical and lateral loads,
• maintenance of correct suspension geometry,
• stable mounting of the hub, bearing, and brake components.

Thanks to its original Audi origin, the wheel hub assembly retains the original suspension operating characteristics, which is important for both driving comfort and safety.

Construction of the Wheel Hub Assembly and Function in the Drivetrain

The presented assembly includes the wheel hub structure with the strut, as well as brake system components such as the caliper and disc. In practice, this means that one module is simultaneously responsible for:

• rigid and precise seating of the wheel hub and bearing,
• correct positioning of the brake disc relative to the caliper,
• transfer of braking forces to the suspension and body,
• cooperation with control arms, bushings, and other elements from the Wheel Bearings, Hubs & Bushings category.

This configuration facilitates servicing, as replacing the complete assembly can in many cases restore correct wheel geometry and operation without the need to intervene in each sub-component separately.

Benefits of Using an Original Audi Part

Choosing a wheel hub assembly from Audi provides a range of practical advantages in daily operation:

• Factory Fit – maintaining original mounting points, angles, and dimensions, which facilitates installation and subsequent geometry adjustment.
• Brake System Compatibility – correct caliper and disc alignment minimizes the risk of uneven pad wear and braking vibrations.
• Handling Stability – a properly selected wheel hub assembly supports even tire wear and predictable vehicle behavior under load.
• Seamless Integration with other suspension elements, including the hub, bearing, and bushings.

Characteristics of a Used Component

The offered component is a used part, representing a reasonable compromise between repair cost and maintaining original Audi structural quality. For many users and workshops, this is a way to economically rebuild the suspension while preserving the vehicle's factory specifications.

Selection and Other Category Elements for Audi

When replacing the wheel hub assembly, it is recommended to always check the condition of cooperating elements such as the hub, bearing, or bushings to avoid repeated suspension intervention in a short period. If expanding the repair with additional components from the same product group, it is worth checking the available Audi Wheel Bearings, Hubs & Bushings – the full offer can be found at the link: Audi Wheel Bearings, Hubs & Bushings.

This allows you to assemble a cohesive set of drivetrain components, tailored to a specific model, which will facilitate workshop work and reduce the risk of part incompatibility.
