Purpose and Vehicle Placement

The steering knuckle is designed for the front left side of BMW E81, E87, E90, and E91 series vehicles. It is responsible for the correct seating of the wheel hub, cooperation with suspension elements, and the steering system, which directly impacts driving stability and safety.

Its placement on the vehicle is clearly defined, which facilitates part selection during collision repairs, replacement of worn components, or comprehensive suspension overhauls.

Technical and Functional Characteristics

The steering knuckle belongs to a group of components that transfer loads from the wheel to the suspension, making its proper geometry and rigidity crucial. The OEM BMW construction ensures:

• correct positioning of the hub relative to the shock absorber and control arms,
• stable mounting of suspension and steering system components,
• preservation of factory wheel alignment angles after correct installation and wheel alignment.

Thanks to this, the steering knuckle can be used for both standard repairs and suspension overhauls after mechanical damage.
