Purpose and Function in the Vehicle

The presented hinge operates in the rear section of the body, responsible for guiding the trunk lid on the left side. Its tasks include:

• maintaining the correct pivot axis of the trunk lid,
• ensuring smooth opening and closing,
• stabilizing the lid's position in extreme positions,
• limiting unwanted play and stress in the mountings.

Thanks to its design tailored for the BMW X5 E70, the hinge works with factory mounting points, which facilitates installation and allows for the preservation of the original geometry of the rear body section.

Color and Visual Fit

The element is made in the shade of Black Sapphire Metallic - 475, allowing for a cohesive match with a body in the same color. In practice, this means a reduced need for additional painting work when installing on a vehicle with a matching finish, as well as an aesthetic integration of the hinge into the trunk lid line.

Technical Characteristics and Installation

The hinge is designed as a dedicated element for a specific model, taking into account the loads acting on the trunk lid and the operation of the entire hinge system. The design includes:

• operation on the left side of the vehicle,
• cooperation with factory mountings of the lid and body,
• appropriate rigidity while maintaining smooth movement.

This solution allows for maintaining correct alignment of the trunk lid with adjacent body elements, which is important for both sealing and the operation of the lock and seals. Dedicated placement on the vehicle minimizes the risk of adjustment problems and reduces installation time.

Item Condition and Service Application

The offered hinge is a used part, making it an attractive solution for accident repairs, replacement of worn-out elements, or restoring the full functionality of the trunk lid on the BMW X5 E70. Choosing an original used hinge allows for maintaining factory fit while reducing costs compared to a new component.

Repair Extension and Correct Part Selection

When working on the rear section of the body, it is worth paying attention to the completeness of the hinge system, the condition of the mountings, and the color consistency of elements cooperating with the trunk lid. Correct component selection is facilitated by identification using the OEM number and interchangeable numbers, as well as verification of vehicle placement and color.
