Purpose and Function in the Bodywork

The presented hinge is dedicated to the rear right side of the trunk lid in W169 series models, where it is responsible for precise guidance and support of the lid during opening and closing. As a structural element working on the lid's pivot axis, it influences:

• maintaining the correct position of the lid relative to the fenders and bumper,
• even load distribution during lifting and lowering,
• limiting stress on the body panels and seals of the rear part of the vehicle.

By preserving the factory mounting geometry, the hinge allows for installation without interfering with the body structure, which is particularly important for post-accident repairs and adjustment of panel gaps.

Horizon Blue Metallic - 391 Color Scheme

The hinge is finished in the Horizon Blue Metallic - 391 color, allowing for an aesthetic match with the bodywork in the same shade without the need for additional painting. This is especially important in the area of the rear lid, where:

• the visible part of the hinge should harmoniously blend with the body paint,
• maintaining color consistency contributes to the visual continuity of the side and rear lines,
• the risk of shade differences due to repainting is reduced.

Such color matching facilitates quick replacement of the part during repairs, shortening the time needed to return the vehicle to service.

Mounting and Operational Characteristics

The hinge is designed for installation in the rear right part of the vehicle, in the area where the trunk lid attaches to the roof structure and the side of the body. The construction, based on the factory solution, ensures:

• compatibility with original mounting points in the body,
• cooperation with the factory lid lifting mechanism,
• stable operation throughout the full range of opening and closing.

As a component from the Trunk Lids & Tailgates group, the hinge is crucial for maintaining the seal of the rear part of the vehicle – correct lid alignment reduces the risk of leaks around the seals and unwanted noises during driving.

Condition and Application in Repairs

The part is a used item intended for reinstallation in a vehicle where the right trunk lid hinge needs replacement. It is particularly suitable for situations where:

• the original hinge has become deformed or cracked,
• there are problems with the lid closing evenly,
• adjustment of the lid position is necessary after body repairs.

Using an original design solution allows for maintaining the performance parameters intended by the vehicle manufacturer, which is important for both durability and user comfort of the rear body section.

Integration with Other Trunk Lid Components

Replacing the right trunk lid hinge should be considered in the context of the entire rear area, which includes the lid, seals, gas struts, and mounting elements.
