Starting about a week agom, i've started getting a bad grinding, squeaking noise when I open or close my door. Just started suddenly....one day it was normal, the next day it was there. Seems to be associated with the keep-open mechanism in the hinges. I thought about spraying some wd40 on it but don't like the way it attracts dust and dirt, so I used siliucone spray instead, but it didn't seem to have any effect at all. Sort of acts like something has broken, due to the fact that it happened so suddenly. Am posting this in the hopes that someone else has had the same problem and will save me the trouble of diging into it. ln my experience, car door hinges are best left alone unless absolutely necessary. Adjusting them can be a real pain.
