Mine was doing this after I replaced the carpet and padding that the slide sits on when in. After some research I found that the carpet and padding was thicker then the factory original carpet and padding. I removed the nice plush padding and my problem went away. My slide was hanging out a 1/2" at the top. If you have redone the flooring this may be your problem. The slide can be adjusted if needed.
