This is probably true but they are a very simple mechanism which should work freely when clean. I've been able to compress the balls and spring inside the tube with a C-clamp but have been unable to transfer the compressed unit into the sliding track. It is very precarious when compressed with a lot of stored energy.
I don't see any possibility of preventative maintenance on the mechanism without removing the whole unit from the door.
