Not that I can see. It’s a multi axis offroad coupler. I pulled the receiver off the truck and tried to figure out a way to get it to bind by hand connected to the trailer and couldn’t.Is the trailer side of the hitch deformed at all? I could see cresting a narrow ridge and as the truck pointed nose down, the trailer might bend the hitch like that.
