Look on the internet for the lube for the slide. About 3/4's of the way up you peal back the rubber seal and lube the motor and slide rail. That takes care of one squeak. This one seemed different. I lubed the seals last night. Was quiet all day for 400 miles of which about 50 were horrible roads. Now the slide went out and it once so perhaps just the connection with side wall. I will try Doug's suggestion if it happens again. I tend to agree with him. If it was the seals it should happen on anything that makes that contact. Now this slide definitely moves more than any others including the Schwintek in the bedroom.
