Purpose and function in the BMW suspension

The steering knuckle integrated with the shock absorber for the rear right side of the BMW 1 Series E87 LCI with the N47 unit is responsible for precise wheel guidance, transferring loads from the body to the hub, and maintaining correct suspension geometry. This component works in conjunction with control arms, the spring, the hub, and the braking system to form a cohesive unit responsible for:

• maintaining specified wheel camber and toe angles,
• vehicle stability during braking and acceleration,
• controlling shock absorber performance on the vertical axis,
• proper transfer of lateral forces during cornering.

The vehicle placement defined as rear – right side eliminates the risk of errors during selection and installation, which is particularly important for components critical to driving safety.

Compatibility, reference numbers, and part selection

The offered steering knuckle with shock absorber is a BMW part with an assigned OEM number and a set of interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration. The presence of multiple reference numbers means that the component was used in various equipment variants and model years, and its selection should be based on:

• comparing the OEM number with the number on the old part,
• verification via VIN in the BMW catalog,
• checking the placement (rear, right side) and body type.

This ensures that the user can be certain the ordered component will be structurally compatible with the factory solution used in their BMW E87 LCI 118d.

Characteristics of the used component

The presented steering knuckle with shock absorber is a used part, sourced from dismantling, which allows for cost-effective suspension repair while maintaining original BMW specifications. A used component is a good solution in situations where:

• mechanical damage has occurred (impact, corrosion, worn mounts),
• a quick replacement of a load-bearing suspension element is necessary,
• you want to maintain factory geometry and mounting points.

Choosing an original, used steering knuckle with shock absorber reduces the risk of fitment issues that may occur with aftermarket replacements featuring different mounting designs or varying performance parameters.

Benefits of installation in a BMW E87 LCI 118d N47

Using this steering knuckle with shock absorber on the right side of the rear axle allows for the restoration of proper vehicle behavior after a collision, curb impact, or long-term wear. Key advantages include:

• factory mounting points for control arms, the shock absorber, and brake components,
• preservation of the rear suspension characteristics designed by BMW,
• possibility of correct geometry alignment after repair,
• consistency with other rear axle components.

For workshops and individual users, this means fewer modifications, shorter installation time, and a predictable end result after assembling the suspension and setting the wheel alignment.
