Trunk Lid Hinge Purpose and Function

The presented hinge is dedicated for installation in the rear, right part of the body, in the trunk lid area. It is responsible for stable guidance of the lid during opening and closing, maintaining the correct geometry, and evenly distributing loads onto the body structure. Thanks to this, the lid operates smoothly, without unwanted play, jamming, or jumping.

Its placement on the right rear side of the vehicle allows for precise fitting to factory mounting points, which facilitates installation and reduces the need for additional bodywork modifications. The use of an original design solution helps maintain the seal and proper fit of the lid to the seals.

Color and Paint Matching

The hinge is finished in Obsidian Black Metallic - 197, which is a significant advantage when repairing bodywork on vehicles with the same paint shade. In many cases, this allows for reducing or completely omitting additional painting work, shortening repair time and lowering its cost.

Color matching is important not only for aesthetic reasons but also practical ones – it minimizes the risk of shade differences between body parts, which is particularly noticeable in dark, metallic colors. As a result, the vehicle maintains a consistent appearance after the repair.

Technical Characteristics and Advantages of Using a Used Part

As a part from the Doors and Door Panels group, the hinge operates in demanding conditions – it handles loads resulting from the lid's weight, user force, and actuator operation. The use of an original design ensures appropriate rigidity, durability of connections, and compatibility with factory mounting elements.

The part comes from dismantling, which in practice means a favorable combination of original component quality with an attractive price compared to new aftermarket parts. For many users, this is a sensible choice for collision or operational repairs where maintaining proper lid function and compliance with factory specifications is crucial.

Practical Application in Service

The right rear trunk lid hinge is primarily used for:

• repairs after collisions involving the rear part of the body,
• replacing worn or bent trunk lid hinge components,
• restoring proper closing and alignment of the lid relative to the fenders and bumper,
• reducing excessive play and creaking during lid operation.

Using an original hinge allows for maintaining factory reference points during adjustment, which facilitates setting gaps and aligning the lid with the rest of the body. This is particularly important in premium vehicles, where the precision of part fitment contributes to the overall impression of quality.
