Slideout not closing
First, check under the slide box on the inside for any obstructions. Loose bolts, nuts, etc.
In the compartment next to the generator is a nut in the overhead inside the compartment. I think it is a 5/8". This nut operates the gear box. Use a socket driver to operate the gear box. If it does not move, you could have a broken shear pin in the gear box or a broken roll pin under the couch that connects the left and right gears.
I have experienced a pin shear in the gearbox but, the slide was making a different noise so, I stopped and brought it back in. I have never brought the slide in manually.
Keep us informed.
