It is a hand-me-down from my father in law. He bought it new and uses it on his farm. I thought it was strange too since both back tires are new and it should have been noticed when they were changed. When I took the wheel off the hub nut was loose and the cotter pin was in three pieces laying in the wheel dust cap. There was some rust on the axle splines so it was loose for a while. To be safe I replaced the hub and it was still a bit looser than it should be so I have an axle on order.
