Purpose and function in the chassis system

This suspension assembly has been designed specifically for Mercedes W212 E 220 CDI models, where it is responsible for the stable handling of the front right wheel, transferring loads from the body to the road, and working in conjunction with the braking system. The integrated brake disc and wheel hub ensure precise rim guidance, while the suspension strut maintains the correct geometry of the front axle.

The placement on the vehicle at the front right side allows for the direct replacement of a damaged or worn component without the need to interfere with other suspension parts. This helps restore proper vehicle handling, reduce vibrations, and improve stability during braking and cornering.

Assembly construction and benefits of a complete module

Combining the suspension strut, brake disc, and wheel hub into one assembly facilitates installation and reduces the risk of errors during system assembly. The modular nature of this component:

• simplifies the service process – fewer disassembly and assembly operations,
• helps maintain proper hub alignment relative to the disc,
• promotes even operation of the braking system,
• facilitates the inspection of cooperating components on the right side.

Additionally, the specified weight of the assembly is typical for a complete suspension module with braking components, which confirms its full service configuration.

Identification parameters and fitment

The item belongs to the Suspension replacement kits category and is intended for Mercedes vehicles. Identification is facilitated by the OEM part number and available interchangeable numbers, allowing for precise verification of compatibility with the specific engine version and equipment of the W212 E 220 CDI. It is worth paying attention to:

• the OEM designation assigned to this type of suspension strut,
• reference numbers used interchangeably in the manufacturer's catalogs,
• dedicated placement on the vehicle – front, right side.

This approach minimizes the risk of selecting the wrong component and allows for maintaining factory handling parameters and braking system performance.

Condition, origin, and practical application

The product is used, which is a beneficial solution for users looking for original components for a Mercedes while maintaining reasonable repair costs. Original parts from disassembly usually work better with the factory suspension geometry than random replacements of uncertain origin.

Due to the nature of the component, installation in a specialized service center is recommended, with a front axle geometry check after replacement. This will allow you to fully utilize the potential of the W212 chassis, reduce uneven tire wear, and ensure predictable vehicle behavior in daily operation.

Complementary elements and system expansion
