I have a '96 26ft Gulfstream Conquest with about a 6ft. slideout. We left the slideout open all last season at our campground. This year we plan to do some traveling but when I tried to close the slideout, it would only go in a couple of inches. Then the hydraulic pump would kick out. After tinkering around, I found the manual lever and I was able to manually bring the room in. I went underneath and Greased the rails and the channels they slide into, sprayed the cables and pulleys with silicone, but no help. Does anyone have any other ideas?
