My right side drawer slide did that in my rockwood 8282ws. Found out that a sofa leg had punched thru floor and twisted the sofa causing the drawer to be in a bind. FR repaired everything for me free at the Goshen rally last year. I'm sorry I don't remember seeing a label anywhere. Maybe you can call forest river for advice. They have contact numbers on this forum.
