I had something similar with my last axle order. When it showed up, the hub face width was 4” wider than what ordered.
I called them up and they apologized and shipped one out quick.
When it arrived, I called the guy up and asked him how I was supposed to get the bad axle back to them.
“I’ll call you back.” That was in may. I’ll be welding up a utility trailer with it soon.
