Mercedes-Benz C E Class W204 W212 Rear Subframe Left N/S Mount Plate Bracket

MERCEDES C W204 left rear beam bracket is a component from the group of longitudinal body frame parts and brackets, designed for use in the rear left zone of the body. It provides stable support for the beam and correct transfer of structural loads within the Mercedes C-Class W204 generation body.

Specifications and technical data

• SKU: A2043520146
• Mark: Mercedes (Genuine OE)
• Condition: Used
• OEM Part Number: A2043520146

• Category: Frame Rails & Subframes

Purpose and Function in the Body

The left rear beam bracket is responsible for a rigid and repeatable connection of the beam to the body structure on the left rear side of the vehicle. A correctly selected component in this area is crucial for:

• maintaining the rear axle geometry during driving and under load,
• stable vehicle handling in corners and during braking,
• even distribution of forces within the longitudinal body frame parts.

The placement on the vehicle, specified as rear – left side, allows for unambiguous identification of the component's position and reduces the risk of errors when selecting parts.

Construction and Fit for Mercedes C W204

This component belongs to the category of longitudinal body frame parts and brackets, meaning it is designed to work in a critical load-bearing area of the body. Its shape, mounting points, and geometry are adapted to the specific rear body architecture of the Mercedes C W204, ensuring that:

• it fits factory mounting points without the need for structural modifications,
• it works with the beam and other brackets within the rear body section,
• it maintains the correct position of the beam relative to the longitudinal members and other frame components.

Such a precise fit is particularly important for collision repairs and for restoring the original body rigidity.

Operational Characteristics

As a structural component, the beam bracket operates under variable load conditions, exposed to torsional and bending forces, as well as vibrations transmitted from the suspension. A correctly selected part helps in:

• limiting unwanted play in the beam-to-body connections,
• reducing noise and vibrations transmitted to the cabin,
• maintaining predictable vehicle behavior during dynamic driving.

Its placement on the rear left side of the vehicle is also significant for wheel alignment control – a stable bracket mounting facilitates maintaining the set geometry parameters.

Practical Application and Installation

The presented bracket is intended for Mercedes vehicles of the C W204 series where replacement of a structural component in the rear left part of the body is necessary. It is suitable for both post-collision repairs and body reconstruction due to corrosion or wear.

• Clearly defined vehicle placement simplifies part identification in catalogs and during body inspections.
• Belonging to the category of longitudinal body frame parts and brackets indicates its use in a load-bearing, not decorative, area.
• The possibility of verification by OEM part numbers and interchangeable numbers allows for precise confirmation of compatibility with a specific body version.

Benefits of Using Original Geometry

Using the appropriate beam bracket in the Mercedes C W204 translates into a number of practical benefits:

• restoration of original rear body rigidity after bodywork repairs,
• increased driving stability when the vehicle is fully loaded,
• improved suspension performance due to proper beam support,
• easier control and adjustment of wheel geometry on the rear left side.

This solution is particularly important for drivers who expect consistent road behavior from their Mercedes and want to maintain driving parameters close to factory specifications.
