2020 Forrest River 26dbud slide out coming out crooked. It’s the rack n pinion style. It’s the left side as your inside the coach. I’ve researched how to adjust the 2 bolts on the motor side and that’s not the problem. As the piston pushes there will s a bar that’s attached to the other side of the slide that causes it to come out. Well, I can see the bar rotating but the gears aren’t moving to push the slide out even. What am I missing?
