Bridget,
I believe that you will need to also replace your wheel rims, due to the proprietary
Uhaul rims.
This is something that I think I would like us to do someday in the future, so that we don't have to experience the fear of broken proprietary parts while on the road. It happened to us once when our hub blew, but we just happened to find a
Uhaul dealer who fixed trailers and who happened to have two hubs in his remaining inventory (dealers are no longer allowed to keep parts, according to him).
