I've seen this kind of wear alot on construction equipment...like air compressors, light towers, small equipment trailers. The mechanics were always on guys to keep the balls greased and clean out the hitch regularly to stop the small rocks and dirt from building up inside the ball socket.
Once a ball starts getting gaulded it is done for and if grease isn't used properly the ball can and will come loose.
Nice repair........

manufactures engineers said that no way could a foreign object that was not metal harder then the ball or coupler could do this…LMAO>>ROTF
Well I can see from this that they are going to tell you it’s not their fault, they are already lying to you. Neither the coupler nor the ball are hardened, if you think I’m wrong take a file out and run it across the ball and hit the top of the coupler. If the file cuts it and it will, they are softer then 62 RC. The ball has chrome plating on it and as soon as it is gone you are down to soft metal. Any stone will cut into the ball, I have 35+ years in the Tool and Die Trade and I will tell their “engineer” the same thing I have just told you, their full of BS. Ask them why is it grinding dust will cut groves in the hardened ways of a grinder?
