Here is what I found out after removing the bed and exposing the mechanism. The main drive shaft is connected to the motor through a transfer case. The end of the shaft has a
drive pin through it, no nut.Using a 5/8 8 point socket I was able to get an electric impact on it but it would not move. Inspecting what is normally inside the coach all the slides were
lubed and clean, the main nut that the drive screw goes through was gummed up. I removed another access panel to be able to see the entire screw assembly and that is where the
problem was. Part of the slides ,once the slide is in the out position, is exposed to the weather. The lube turned to a gummy paste and jammed the slide. A good cleaning and using
a different lubricant I got the slide to work properly. The next time the slide is out I am going to inspect and clean as necessary. Amazing how a little dust and dirt can change your
day.
