Purpose and Fitment for BMW E82 123d

The offered component combines the function of a strut and a knuckle on the right side of the front axle, simplifying servicing and reducing repair time. The use of BMW's factory design ensures the correct positioning of the hub, suspension mounts, and attachment points for the braking and steering systems, which translates to predictable car behavior in corners and during braking.

As a part from the Suspension Replacement Kits group, it provides a mechanic with a cohesive set of components that allows for precise restoration of factory suspension operating parameters without the need to match various sub-assemblies from multiple sources.

Construction and Function of the Strut-Knuckle Assembly

The integration of the strut and knuckle into a single assembly ensures rigid and stable wheel guidance, while also providing adequate damping of vibrations from road imperfections. The knuckle is responsible for:

• maintaining the correct position of the wheel hub and bearing relative to the body,
• providing mounting points for control arms, tie rods, and the brake caliper,
• stable wheel guidance during changes in load and direction of travel.

The strut within this assembly controls spring movement and limits body roll, improving ride comfort and tire grip. The use of BMW's original design promotes the preservation of the correct damping characteristics, factory-tuned to the weight and nature of the 123d model.

Vehicle Placement and Benefits of Replacement

This component is intended for the front, right side of the vehicle, which is crucial for maintaining correct suspension geometry and even tire wear. Replacing the complete strut-knuckle assembly is particularly recommended in situations where:

• the suspension has been damaged after a collision or hitting an obstacle,
• there are noticeable play or knocking noises in the front suspension on the right side,
• the car pulls to one side when driving straight or braking,
• irregular tire tread wear is visible on the right wheel.

Using the original assembly allows for the restoration of factory camber and toe angles, which facilitates subsequent geometry adjustment on a measuring stand and reduces the risk of recurring steering problems.

Original Origin and Interchangeable Numbers

The presented assembly comes from the BMW OE line, signifying compliance with the manufacturer's original design and material standards. The part has a dedicated OEM number and a set of interchangeable numbers, allowing for precise verification with the BMW catalog or service software. This simplifies selecting the correct component for a specific equipment version and model year of the BMW E82 123d.

The presence of reference numbers also allows for comparison of the offered part with other variants used in this series, which is useful when planning repairs or suspension upgrades on modified vehicles.

Condition, Application, and Practical Tips

The component is offered as used, removed from a vehicle, representing a reasonable compromise between repair cost and maintaining BMW's original design. This type of solution is often chosen by discerning users who prefer used OE parts over cheaper aftermarket alternatives with uncertain operating characteristics.
