I looked through some posts, and didn't see this particular problem. Our dining room slideout started going very slow, in and out. Also, since this started, it is putting three orange lines on the linoleum floor. Not rusty orange, but marks that look like a crayon, but don't rub off. I lubed everything I could see underneath, and it's quieter, but something must be out of whack to make those marks. sound familiar to anyone?
