Application and Function in the Vehicle

The presented hinge is intended for installation at the rear of the body, on the right side, in the Mercedes A-Class W177 generation. It is responsible for the stable guidance of the trunk lid, its proper opening geometry, and the even distribution of loads during the operation of gas springs and the lock. A correctly selected hinge reduces stress on the lid panel and fenders, which translates to a longer lifespan for the entire rear section.

Color and Paint Matching

The component is finished in the factory color Mineral Grey Metallic – B39, used in Mercedes' paint palette. For the user, this means the possibility of replacing the hinge while maintaining color consistency within the trunk recess and lid edges. In many cases, this allows for limiting the scope of painting work to potential spot repairs, which shortens repair time and reduces costs.

Technical Characteristics and Installation

The hinge belongs to the group of Gas Springs, Locks, Hinges, and Other Parts, i.e., components responsible for the mechanical operation of the trunk lid. The construction has been designed for factory mounting points in the body and the lid, which facilitates installation and allows for maintaining original gaps and sealing lines. The appropriate shaping of the hinge arm ensures the correct opening and closing angle of the lid, as well as cooperation with actuators and the lock without the need for body modifications.

As a used part, the hinge comes from a dismantled vehicle and is a particularly beneficial solution for accident repairs, where both correct fit and cost control are important. The original design ensures compatibility with factory mounting elements and seals around the rear lid.

Practical Application and Benefits of Choosing a Used Part

Choosing an original, used rear trunk lid hinge for the Mercedes W177 allows for maintaining the factory trunk opening geometry and proper cooperation with other components in this area. This is particularly important for:

• repairs after collisions in the rear of the body,
• replacing a bent or seized right-side hinge,
• restoring full lid functionality after bodywork and painting interventions.

Part Selection by Markings and Numbers

This trunk lid hinge is an original Mercedes part, bearing an OEM part number and associated interchangeable numbers, which facilitates precise identification in manufacturer catalogs or by VIN number. This allows for verifying compatibility with a specific body version and year, minimizing the risk of purchasing an incompatible component. If necessary, it is advisable to compare the shape and mounting points with the currently installed hinge on the vehicle.
