The pictures don't tell the whole story. Had I known at the time that I would be showing these pics I would have gotten better ones. These cabinets were basically being supported by the raised panels on each side. The joints suddenly started to give out and the whole front of the cabinet was about to fall. There was little if any glue in the joints. I took the cabinets down and squared them up. After that I glued and pocket hole screwed the joints on the raised panel sides. The sides are still the structural support for the cabinets but they are much more solid now. And the panels can still expand/contract if needed. There might be a better fix, but this is what I came up with.
