Purpose and function in the vehicle

The described suspension assembly has been designed specifically for the rear, right side of the body, where it is responsible for transferring loads from the wheel to the body and stabilizing the vehicle during acceleration, braking, and cornering. Integrating the suspension strut, wheel hub, and brake disc into a single module facilitates service, shortens repair time, and reduces the risk of installation errors.

Thanks to the factory design, both the wheel position in the wheel arch and the cooperation with the braking system and safety systems are correct. This is particularly important in Mercedes-class cars, where steering precision and predictable body behavior are crucial for driving comfort.

Suspension kit construction and benefits of complete replacement

In one module, you receive the elements responsible for wheel guidance, its mounting, and cooperation with the braking system. This configuration allows for the following during a single service operation:

• restoring the correct seating of the wheel on the hub,
• minimizing play and unwanted vibrations within the rear axle,
• maintaining proper cooperation with the brake caliper and disc,
• reducing the need for repeated disassembly of the same elements.

The complete suspension assembly on the right side of the rear axle is particularly useful after collisions, mechanical damage, or in the case of advanced wear of several components simultaneously. Instead of selecting individual parts, you can use a ready-made module, which facilitates workshop work and speeds up the vehicle's return to service.

Original Mercedes component – fitment and identification

The product comes from the Mercedes offer, which means maintaining factory design parameters, geometry, and material quality. The original suspension assembly ensures proper fitment with the body, compatibility with factory mounts, and predictable vehicle behavior after repair.

To ensure the correct selection of parts, it is worth using the OEM number and interchangeable numbers, which are listed in the technical specification. This facilitates verification of compatibility with a specific engine version and vehicle equipment. If you want to check step-by-step how to properly match a component by catalog number or VIN, the following guide will be helpful: how to choose the right car part by VIN and OEM number.

Condition, installation, and service application

The item is offered as a used suspension assembly, which is a reasonable compromise between the cost of repair and maintaining the original manufacturer's quality. This type of solution is often chosen for post-accident repairs when larger parts of the suspension system require replacement, and purchasing new components would be economically unjustified.

The location on the vehicle has been clearly defined as the rear right side, which minimizes the risk of error during ordering and installation. The suspension assembly is intended for installation in place of the factory element, using original mounting points and standard service procedures used in Mercedes vehicles.

Support with selection and other Mercedes suspension kits

If you are planning a comprehensive repair or upgrade of the suspension zone in your Mercedes and need other elements from the same group, such as additional struts, hubs, or complete rear axle modules, check the available parts in the Mercedes suspension replacement kits category.

When choosing used suspension components, as with other key subassemblies, it is worth knowing the differences between regeneration and the use of original parts from dismantling.
