Had roller on closet side of bed room slide screws sheered off. Roller held in place with screws from the top, roller must have been attached before slide installed. Any thoughts on how to get roller reattached with out going to dealer and having slide removed? It's on a Sundance 2012 unit. May be able to attach with screws on the side rather than top, not sure how much weight is on roller and if it will hold.
