I don't have this issue with this coach, but I have some friends that did have this type of issue. They used birthday candles to fix the binding. Open the door all the way, clean the track of dust and debris. Take a B-bay candle and using the flat end rub it in the groove of the track on both sides. Then open and close the door a few times. You may need to do it more than once to get them slipping. The wax will not cause the material to swell up like a liquid lube will, and should reduce the binding that is causing the problems that you are experiencing.

Good luck!
