Purpose and Function in Suspension

The rear right knuckle hub assembly is responsible for precise wheel guidance and transferring loads from the road surface to the suspension. It is a key element for:

• maintaining the correct rear axle geometry,
• vehicle stability during acceleration and braking,
• proper operation of the wheel bearing and mounting elements,
• even tire wear and correct tread contact with the road surface.

Thanks to its specific side fitment (rear, right side), installation is straightforward, and the risk of incorrect installation is minimized.

Compatibility and Reference Numbers

As an OEM part from BMW, the knuckle hub assembly is designed to work with the factory suspension and braking system of the relevant models. The presence of a dedicated part number and associated interchangeable numbers facilitates selection by catalog, VIN, or service documentation, which is particularly important for professional workshops.

If you are planning a more extensive repair or upgrade of the drivetrain, it is worth considering selecting other components from the same line to maintain consistency in suspension performance parameters.

Condition, Application, and Benefits of Installation

The component is offered as a used OEM part, allowing for savings while maintaining original construction and mounting points. This is a practical solution in situations such as:

• repair after mechanical damage (e.g., hitting a curb, collision),
• restoring correct geometry after detecting a bent or cracked knuckle,
• suspension service for fleet and private vehicles where repair economy is important.

Installing an original knuckle hub assembly helps reduce additional adjustments and fittings, which are typical for aftermarket replacements with poorer manufacturing tolerances. A correctly selected component affects handling stability, driving comfort, and predictable vehicle behavior in corners.

Performance Parameters and Tire Selection

The product is designed to work with a specific tire profile, which is important when configuring wheels and suspension. Maintaining compliance with the vehicle manufacturer's recommendations regarding rim and tire sizes allows for proper drivetrain operation, avoids excessive bearing loads, and preserves factory traction characteristics.

When replacing the knuckle hub assembly, it is recommended to simultaneously check the condition of the bearing, mounting elements, and wheel alignment to fully utilize the potential of the newly installed component.
