Definition and construction of a crossover

A car steering knuckle is a massive metal component, usually made of steel or aluminum, that connects the wheel hub to the suspension and steering system. It includes, among other things, the shock absorber mounting eye, the wheel bearing housing, and the ball joint sockets. Vehicles such as the Audi A6 C6 and BMW E46 use steering knuckles of various sizes and camber angles, adapted to the suspension geometry of the given model. Aluminum versions, found in the Audi A4 B8, for example, are characterized by lower weight, which translates to better handling and lower fuel consumption.

Why are crossovers so important?

Steering knuckles are one of the most important components of the suspension and steering systems. They are responsible for connecting the wheels to the rest of the vehicle, and their precise operation influences aspects such as:

• Vehicle stability – Steering knuckles ensure optimal wheel alignment angle, which has a direct impact on driving comfort and safety.
• Precise maneuvering – Thanks to the steering knuckles, the car responds to every movement of the steering wheel, enabling confident and smooth driving.
• Reduced tire wear – Properly functioning steering knuckles minimize the risk of uneven tire wear, which translates into savings. Whether you're driving in the city or on long journeys, steering knuckles play a crucial role in your daily driving experience.

Compatibility and technical parameters

Steering knuckles differ in design, so it's crucial to choose a part compatible with your specific vehicle model . For example, the Audi A3 8P steering knuckle differs in bearing diameter (82 mm) from the Audi A4 B8 steering knuckle (85 mm), even though both belong to the same VAG group. BMW models, such as the E36 and E46, feature different variants depending on the drive type – rear-wheel drive and front-wheel drive versions have different mounting points.
