Purpose and Function of the Trunk Lid Hinge

The presented hinge is dedicated to the rear right side of the trunk lid in Mercedes W164 models. It is responsible for precise lid guidance along the opening and closing path, transferring loads resulting from the lid's weight, and maintaining the correct position relative to the body. A properly selected element of this type reduces the risk of edge rubbing, leaks, and excessive play in the closed area.

Construction, Color, and Body Fitment

The hinge operates at the rear of the body on the right side, collaborating with the lid's structure and the perimeter seal. The design intended by the vehicle manufacturer allows for the preservation of factory mounting points and correct movement geometry. Thanks to the finish in the Tanzanite Blue Metallic - 359 shade, the part can be used both for accident repairs and for replacing a worn hinge on a vehicle with the same paint code, thus reducing the scope of additional painting work.

Benefits of Using an Original Rear Trunk Lid Hinge

Using an original hinge at the rear of the body translates into a number of practical operational benefits:

• maintaining the original trunk lid line relative to the fenders and bumper,
• proper cooperation with the lifting actuators and the trunk lock,
• reducing loads acting on the mounting panels and screw points,
• minimizing noises resulting from play and improper closing,
• easier adjustment of the lid's position during installation.

An element from this group is particularly important for repairs after rear-end collisions, where even minor deviations in hinge geometry can cause problems with closing or trunk leaks.

Condition, Installation, and Service Application

The offered hinge comes from a used vehicle, allowing for economical repair while maintaining the original construction. This type of part is frequently used in body and paint shops for the reconstruction of the rear body section, as well as for replacing worn or bent hinges after many years of use. Installation is carried out at the factory mounting points, using appropriate screws and lid position adjustments, which allows for precise alignment of gaps and planes.
