I have never seen a hitch seize in, many many slop around and rattle. If it is not welded, then it is one in a million.
That means I learned something today, every truck I have ever seen, even without a load the hitch slops around. The only ones I have ever seen that do not rattle are the ones I built, and they have a longer receiver, and are bolted with two boltsSeen it plenty of times. Someone buys a truck with a hitch, installs a receiver with "their" ball and leaves it there because all they tow is a little 4x8 utility trailer. After a few good winters, all the rust swells up and locks the receiver in the tube. Without towing something heavy, it never gets a good work out to wobble the tube bigger.
Our company F100 had the same issue. I finally got them to leave receiver in the cab until the few days a year it's needed. That way it's not stuck(like it was one day I tried to remove it becasue I got tired of knocking my knee into it).
I see them rusted in all the time.I have never seen a hitch seize in, many many slop around and rattle. If it is not welded, then it is one in a million.
