Purpose and Fitment for W639 Bodywork
This hinge is dedicated to the rear section of the body, on the right side, for W639 series vehicles. Its design has been developed to maintain the correct geometry of the trunk lid suspension, which translates to:
- proper closing and opening of the trunk door without jamming,
- stable guidance of the tailgate throughout its full range of motion,
- maintaining the seal of the door perimeter against the bodywork.
Thanks to its factory origin, the hinge works with original mounting points, facilitating installation and minimizing the need for additional adjustments.
Arctic White - 9147 Color and Visual Aspect
The part is finished in the Arctic White - 9147 shade, used on the bodywork of this series. This allows for an aesthetically pleasing integration of the hinge into the car's lines, without visible color differences on the rear of the vehicle. In practice, this means:
- a consistent look of the rear tailgate after replacing the part,
- no need for additional painting if the body color matches,
- preservation of the factory finish character.

Performance Characteristics and Installation
The rear tailgate hinge in this variant is designed as a component operating on the axis of the trunk door opening, bearing the loads resulting from the tailgate's weight and forces encountered during operation. The appropriately selected geometry and structural rigidity contribute to:
- reducing play in the trunk door mounting,
- minimizing the risk of the tailgate sagging or becoming misaligned,
- maintaining proper sealing of the gaskets.
The part comes from disassembly, allowing for the preservation of original manufacturer specifications while reducing repair costs. This is a solution often chosen for bodywork servicing when the priority is to combine factory fit with a reasonable budget.
Why Choose a Used Trunk Hinge
For components like trunk door hinges, using a used part of factory origin is a rational compromise between cost and functionality. You receive a component consistent with the vehicle's construction, which allows for restoring proper tailgate operation without the need to invest in more expensive solutions.
