This one has been bugging me for a while, and I've been meaning to ask about it. It has to do with operating the kitchen and living room slides. When I run the room all the way out or all the way in, I get a clack-clack-clack sound at the end of travel. I try to be very careful and let my finger off the switch right before it reaches the end of travel. Some folks say that's just the clutch, and it's normal. Others say it's out of adjustment and needs to be fixed. Does anyone else's Reflection do this? Is it normal? Will it hurt anything?
