I reassembled and there is enough play make me believe there should be some washers in there. who would sell/stock washers like these? they have to be big but are mostly hole. I have another pair from another trailer so I have a reference. I tried the local auto parts store (weaver) and they can’t get them and don’t stock them. etrailer.com has some but they have a flat edge on the round inside that must be for a spindle with a flat spot.

any ideas? probably will have to try McMaster carr.
