Wonder if myb can help with this one. My mazda etude was in a left-side smash a few years ago. Now the passenger door is making a bad creaking noise when opening/closing. It happens at each lock on the door travel. I suspect it's that black joining arm between the 2 hinges. I've sprayed q20 but the noise is still there. Anybody had any experience like this or know what this joining arm is called or what could be causing this noise?
