Slide outs scratching floor.
2007 Monaco Executive: two slide retract with clearance over the floor. Just before the slide is fully retracted, the inside edge of the slide drop down and touches the floor, causing the scratching. I found a piece of a small broken wheel under one of the slides. If there are small wheels under the slides, how do I access them? The only adjustment I find is through a round hole in the side of a horizontal rectangle support that supports the slide. There is a threaded shaft inside this hole where there is an adjustment nut and a locking nut on the shaft.
I don't know what to do next?
