Purpose and vehicle placement

The presented steering knuckle is a suspension system component mounted on the rear axle on the left side. It is responsible for precise wheel guidance, transferring loads from the body to the ground, and working in conjunction with other suspension and braking system components. A correctly selected steering knuckle is crucial for maintaining driving stability, even tire wear, and the proper operation of safety systems.

Technical characteristics and compatibility

The steering knuckle has been designed specifically for the Mercedes W203 C 220 CDI model, which means it is compatible with factory mounting points and geometric parameters specified by the manufacturer. The item belongs to the Suspension replacement kits group, making it suitable for both standard repairs and comprehensive rear suspension rebuilds. The product has a dedicated OEM part number and associated interchangeable numbers, which facilitates verification of compatibility with a specific vehicle version.

Benefits of using an original steering knuckle

Using a steering knuckle designed for a specific Mercedes model allows for the preservation of factory handling parameters and ride comfort. The main advantages include:

• proper fitment for the rear left side without the need for modifications,
• maintenance of correct suspension geometry after wheel alignment,
• consistent cooperation with other chassis components,
• suitability for use as part of a broader suspension replacement kit for this model.

As a result, the steering knuckle provides a solid foundation for restoring proper vehicle handling after mechanical damage or operational wear.

Condition of the component and practical application

The offered steering knuckle is an aftermarket component, which allows for economical repair while maintaining a design consistent with the original. This type of solution is particularly beneficial for post-accident repairs when it is necessary to replace several rear suspension elements simultaneously. A properly selected and inspected used component can effectively restore the correct operating parameters of the chassis without placing an excessive burden on the budget.
