Hi, I have bought a used 1999 Transit Camper 2 years ago. The closing of the sliding door was worsening since then. Now, it only closes with force after many attempts. A friend that drove the car told me that it event opened by itself when he was driving on a veeery bumpy road.
It seems like that there is some kind of resistance that does not allow the back part of the door to close and lock properly. I have made a video, because it is much easier to understand.
I have applied WD40 to all moving parts involved with no improvement.
Please let me know: What would you do in order to fix the problem?
