Vehicle Application and Function

This kit, from the Suspension Replacement Kits category, is designed for the rear axle on the left side. The knuckle serves as the central mounting point for suspension and brake system components, transferring loads from the wheel to the body and working with other components of the BMW X3 F25 30dX N57N rear suspension.

The placement on the vehicle, specified as rear – left side, ensures unambiguous installation identification, minimizing the risk of part selection errors. The integration of the knuckle with the brake caliper and disc helps maintain the consistency of the suspension system's geometry and operating characteristics.
