Used Heater Core

Front door hinges carry the full weight of the door and endure thousands of open-close cycles over the life of the vehicle. Worn hinge pins cause the door to sag, which shows up as difficulty closing, misaligned latches, and gaps between the door and body that let wind noise in at highway speed. Redline has 2 used Heater Core listings from 1 verified sellers across 2 makes, including Mercedes Benz, Bmw vehicles. Each door has an upper and lower hinge, and both must be in good condition for the door to hang correctly. Replacing just one while the other is worn will not fully correct the sag. Order as a pair if possible. Door hinges are left-and-right specific because the pin orientation is mirrored. Also check whether your vehicle has check straps or spring-loaded detents built into the hinge that hold the door at specific open positions. These integrated features vary between models and affect the hinge part number.
