Purpose and function in the suspension

The rear knuckle with hub in the Audi A8 / S8 D4 is responsible for stable wheel mounting, transferring loads from the control arms, and maintaining the correct position of the hub relative to the body. Its placement on the vehicle is the rear left side, which is important when selecting parts in relation to other suspension and braking system components.

This element works with control arms, the wheel bearing, and bushings, creating a rigid yet appropriately flexible system that influences:

• maintaining correct wheel alignment and camber,
• even tire wear,
• vehicle stability at higher speeds,
• driving comfort when overcoming bumps.

Original Audi origin

The presented knuckle comes from the Audi brand, which means maintaining factory design parameters and full compatibility with the suspension system of D4 generation A8 and S8 models. Original manufacturing translates into proper fitment with other components, without the need for modifications or adjustments to mounting elements.

Thanks to this, the part is suitable both for standard replacement of worn components and for repairs after mechanical suspension damage, where restoring the original axle geometry is crucial.

Used condition and benefits of choosing

The knuckle with hub is offered in used condition, which allows for a significant reduction in repair costs while maintaining the manufacturer's original specifications. This solution is particularly beneficial for comprehensive work within the rear suspension, where several elements are often replaced simultaneously.

Choosing a used OEM component is a reasonable alternative to cheaper replacements of uncertain quality, especially in high-end vehicles such as the Audi A8 and S8, where driving precision and comfort are of significant importance.

Selection and compatibility

To correctly select the knuckle for a specific vehicle, it is worth paying attention to data such as manufacturer markings, body version, and suspension configuration. The product has an assigned OEM part number and interchangeable numbers, which facilitates verification of compliance with Audi's factory service documentation.

Additionally, information such as SKU, brand, condition, and placement on vehicle is available in the product card, which helps to quickly confirm that this is the correct rear left suspension element for your model.

Repair expansion and related elements

When replacing the knuckle with hub, it is worth considering simultaneous inspection of other components from the Wheel bearings, hubs and bushings group, such as wheel bearings, control arm bushings, or other hubs on the same axle. If you are planning a comprehensive repair or upgrade of the rear axle suspension zone in your Audi and need other elements from the same group, such as additional hubs, wheel bearings, or mounting bushings, check the available parts in the Audi Wheel bearings, hubs and bushings category.
