In my opinion you will be needing new bearings as the are pretty damage and the expanders will not do their intended job. This is what happens when someone pulls the bearing caps and doesn't remove the screws from the expanders. Bearings are getting a little tough to find but they can be found. I think a guy parted out a 10 on ebay and the bearings may still be available.
He might have sold them, there was a set with the expanders posted a few days ago.The only ones I see on ebay are for a 10K..
