Audi A5 S5 8T Wheel Carrier Rear Left N/S Wheel Hub Bearing 8K0505431AH

Audi A5 S5 8T Wheel Carrier Rear Left N/S Wheel Hub Bearing is an original suspension component from the Suspension Replacement Kits group, designed for the rear axle on the driver's side. Thanks to its factory design, Audi ensures proper geometry, stable handling, and precise seating of the wheel hub and bearing in A5 and S5 8T series models.

Purpose and function in the suspension

The rear left wheel carrier is responsible for the stable connection of the wheel hub with control arms and steering components, as well as maintaining correct suspension angles. In practice, this means:

• reliable vehicle handling at higher speeds,
• even tire wear due to maintained geometry,
• proper cooperation with the braking and drive system of the rear axle. The placement on the vehicle, defined as rear – left side, allows for precise selection of the component for a specific position in the suspension, which minimizes the risk of errors during ordering and installation.

Original origin and compatibility

The presented wheel carrier comes from the Audi brand, which means maintaining factory design parameters and full compatibility with the solutions used in A5 and S5 8T generation models. The component has a dedicated OEM part number (visible in the specification section), as well as assigned interchangeable numbers, which facilitates verification of compatibility with a specific body version and drivetrain. Thanks to this, the part can be safely used as a replacement for a damaged wheel carrier in vehicles where it is required to maintain the original suspension performance characteristics and proper cooperation with other rear axle components.

Characteristics of the used component

The wheel carrier is offered as a used original part, which in practice means a real compromise between the cost of repair and maintaining factory build quality. In the case of suspension components, such a solution is often chosen for:

• post-accident repairs,
• mechanical damage resulting from hitting a curb or a pothole,
• the need to restore correct geometry after replacing other components. The used OEM component retains the original design and mounting points, which facilitates installation and reduces the need for additional modifications.

Benefits of using an original rear left wheel carrier

Using this wheel carrier in an Audi A5 / S5 8T allows you to:

• maintain factory handling and stability parameters,
• ensure correct seating of the wheel hub and bearing,
• maintain compatibility with standard control arm and shock absorber mounting points,
• reduce the risk of alignment issues after repair. For workshops and users, this means predictable installation and easier geometry control after replacing the suspension component.

Selection and expansion of suspension repair

When replacing the wheel carrier, it is worth paying attention to the condition of other rear axle components – especially control arms, bushings, and the wheel bearing. In the case of the Audi A5 / S5 8T, a broader suspension service is often performed at this time to avoid re-disassembly in the near future and to restore consistent vehicle behavior on the road. If you are planning a comprehensive repair or upgrade of the suspension area in your Audi and need other elements from the same group, such as wheel carriers, hubs, or complete mounting modules, check the available parts in the Audi Suspension Replacement Kits category.

Technical support and knowledge about used suspension

When selecting used suspension components – especially in cars with a more dynamic character, such as the Audi A5 and S5 – it is crucial to understand the differences between standard and sport configurations and to have an informed approach to purchasing second-hand parts. To better plan your repair and assess when a used wheel carrier will be the right choice, it is worth checking out our guide: Standard vs. sport suspension – differences in design and is it worth buying used suspension parts?.
