Slide out

[RWD40]

I just registered on this website so please bear with me.
I have a 2018 Aspen Trail 29 ft. with bunk room. I want to sell it but the slide out needs adjusting. I don’t even know what kind it is. When bringing it in it goes too high and hits the ceiling on the right front side. I have to step on it to lower it enough to get all the way in without rubbing on the ceiling. Once it’s in it’s not touching the ceiling but the floor is raised up on this side only. It’s been doing this for a while now and today it got worse. Any ideas? Thanks everyone.

Hi, first, what type of mechanism does it have? Cables? gears on the sides, worm on the bottom?

I don’t know what type of mechanism my rv has on the slide. It has 2 rails it rides on.
