Purpose and function in the suspension

The steering knuckle with axle shaft for the rear right side is responsible for precise wheel guidance, transferring loads from the body to the road, and working in harmony with other suspension components. In the BMW 1 Series E87 model with the 163 HP M47N2 engine, this component is crucial for:

• maintaining proper rear axle wheel geometry,
• stability during acceleration and braking,
• controlled vehicle behavior in corners,
• even tire wear.

Thanks to a design compliant with the manufacturer's specifications, the knuckle works with factory mounting points, which facilitates installation and allows for the preservation of original BMW handling characteristics.

Technical specifications and fitment

This element belongs to the Suspension replacement kits group, meaning it is intended for comprehensive work on the rear axle – especially where simultaneous replacement of several suspension components is necessary. Its specific placement on the vehicle reduces the risk of errors when selecting parts and allows the mechanic to quickly identify the correct component.

The knuckle with axle shaft is prepared to work with factory BMW solutions, which minimizes the need for modifications and allows for maintaining consistency with the original suspension design. This is particularly important in cars where handling precision and predictable steering response are prioritized.

Condition, origin, and benefits of choosing a used part

The part comes from the BMW segment and is marked as used, which allows for a significant reduction in repair costs compared to new aftermarket replacements, while maintaining the original manufacturer's specifications. A used OEM component is a good choice for drivers who want to:

• maintain factory suspension parameters without overpaying,
• preserve compatibility with other rear axle components,
• limit the risk of fitment issues associated with non-original parts.

Before installation, standard condition verification by a mechanic and subsequent wheel alignment are recommended to fully utilize the potential of the suspension system and ensure stable rear axle operation.

Application in service, repairs, and tuning

The rear right steering knuckle with axle shaft is suitable for both typical repairs following mechanical damage and for suspension upgrades aimed at a more dynamic character. Replacing this element is especially recommended when there are issues with geometry, uneven tire wear, or after a collision involving the rear axle.

For users interested in the broader use of used components in repair and tuning projects, valuable tips can be found in the article Audi on second-hand parts – tuning and repairs without compromising quality, which discusses a practical approach to using second-hand components in German cars.
