I have a 32ft enclosed car trailer that since 1999 I have probably 200,000mi with the same ball on several different trucks and I never grease it. It shows some wear but nothing I am concerned about. Had a ball shear off once but thats a different story.
^This.
While I don’t track mileage on my trailers or any work trailers, even with old work trailers that certainly have far more use than most dedicated recreational uses, I’ve yet to see a ball or coupler “wear out .” Broken, smashed, rusted, yes.
Can’t say I’ve even recall seen that type of grinding as those pictures.
