Purpose and configuration of the component

The described suspension assembly has been designed specifically for the Mercedes C-Class S203 generation model with a 270 CDI engine, as a component mounted on the rear right side of the vehicle. Combining the suspension leg with the wheel hub and brake disc in one module ensures geometric consistency, proper wheel tracking, and stable interaction with the braking system.

Placement on the vehicle on the rear axle on the passenger side allows for precise alignment with factory mounting points, which limits the need for additional modifications and makes it easier to maintain the correct suspension performance characteristics.

Construction and function of the suspension assembly

The complete assembly includes the suspension leg, wheel hub, and brake disc, creating a functional module responsible for wheel guidance, load transfer, and interaction with the braking system. This configuration:

• ensures stable seating of the wheel on the hub,
• enables effective transfer of forces from the road surface to the body,
• guarantees correct positioning of the disc relative to the brake caliper,
• facilitates inspection and service of the entire suspension corner.

Thanks to maintaining the factory design, the system works with the standard rear axle geometry, which promotes predictable vehicle behavior during braking, acceleration, and cornering.

Benefits of using a complete set

Using a complete suspension assembly with a hub and brake disc reduces the risk of mismatching individual components and speeds up workshop work. Replacing the entire module in one process:

• simplifies installation and removal,
• reduces the number of potential points for play and noise,
• facilitates subsequent rear axle geometry adjustment,
• ensures consistent wear of cooperating components.

For the user, this means more predictable handling, stability at higher speeds, and better control over the vehicle in daily operation.

Product characteristics and practical application

The component comes from a Mercedes vehicle and complies with the manufacturer's factory specifications, which helps maintain the original driving characteristics of the S203 270 CDI model. The product has an assigned dedicated OEM part number and associated interchangeable numbers, which facilitates unambiguous identification in catalogs and service systems without the need for interfering with the vehicle's construction.

Due to its nature, this is a solution particularly useful for post-accident repairs, replacing worn rear suspension components, or restoring full performance of the chassis in cars used intensively, e.g., on long routes.

Condition, origin, and technical aspects

The product is offered as a used part, which allows for economical repair while maintaining the original design and compatibility with Mercedes factory solutions. The assembly has a specific weight, typical for a complete suspension module with a hub and disc, which should be taken into account when planning installation and handling the component in workshop conditions.

To facilitate selection and handling in the warehouse system, the product is marked with an individual SKU and OEM part number, as well as a set of reference numbers that allow verifying compatibility with a specific vehicle configuration and production year.
