I cleaned up the hitch pieces and installed a grease fitting. I only used one zerk in the middle after seeing how it was built. The end plates act as the bearings for the shaft and the pipe center has about an 1/8" larger Dia. so it will just get filled with grease and push out of the ends. I don't think it will ever seize up again. I hope this is the last surprise that needs to be fixed and I can get this put back together this coming week.
