Hmmmm, that is possible. I am referring to towing with a Hensley (at least for me, never liked towing without one). But the physics seems to make sense. Place a bar into a box, that is not precision fit, crank a 1000 pound bind on it, and from time-to-time, it is going to "clunk" But maybe its not on all hitches.

And, I was being serious. Between the A frame mounted bike rack and excessive side scrubbing of the tires, I try not to turn sharp. I'll pull back and forth multiple times to avoid.....and mirror visibility is better that way too.

This thread is applicable to my sloppy shank to receiver fit I had a couple of years ago. I discovered a bent hitch pin while towing. Not good. I found my shank fit so poorly in the receiver that the hitch pin is what resisted torsional forces.
The situation was made worse in my case as my Super Duty came with a 2 1/2 receiver as well as a reducer sleeve to get to 2" square. There was clearance slop between both members. Again, the hitch pin was getting pinched, and the holes in the receiver were getting elongated.
I found a Curt Mfg. reducer sleeve that fit rather tightly in the Super Duty, better than the Ford supplied one. Then I welded the Curt reducer sleeve to the Pro Pride shank eliminating any slop between those two members. The heat of the weld distorted the Curt reducer enough that I had some serious power sanding to finally get a loose enough fit that I could assemble the shank to the receiver. These steps eliminated most of the slop.
I can now twist my shank using my Rock Tamer bars and the hitch pin stays free, or unbound. And my hitch pin is free and unbound when the trailer is connected and weight bars tightened. I do not believe the hitch pin was designed for any torsional forces, only sheer with the acceleration and braking forces.
So if the slop is great enough that it binds the hitch pin, I recommend figuring out a way to eliminate it. Weld build up on the shank, and then ground to a good fit would work in my view. I would use a bead weld, not a spot weld. You need some good bearing area so you don't wear the receiver. I also purchased a better hitch pin for added security. I even keep a grade 8 bolt in the tool box just in case I see anything unusual with the hitch pin.
By the way, I could not detect any difference in towing or noise before and after I eliminated the sloppy fit.

I bought an anti-rattle device- basically a U-bolt and a flat piece of metal turned up at one end.

I know there is a bolt on device to remove the play but you have to unbolt it every time you want to remove the head. That doesn't sound too convenient.

Spot Welding sounds kinda "Buckshee"! It'll work, but I have a better way.
I have a Husky hitch, with a Hidden Hitch on the tow vehicle, pulling a Hi-Lo. [ I don't have an Airstream yet.] I measured .064 play between the hitch shank and the receiver.
So, I made two shims .060, one for the side, [pin hole drilled], and the other for the top. If I can send you a photo or two, I'll try to.
In keeping with my old Air Force Sgt.s. dictum; "if it moves, lubricate it; if it doesn't paint it; if it talks back, salute it!"
Since there is a modicum of movement there, I grease the shank using heavy grease, and lube the spring bars with Moly-Slip.
It works; no rattle, and the hitch comes out easily.

The hole for our hitch pin has worn oval on one side. This is in part due to the slop between the shank and receiver, with the TV dog tracking causing the shank to put excess load on one side of the receiver.
Back in the 70s, I worked at a hitch mfg. and heard of a person driving 500 miles without the hitch pin in and they didn't lose the trailer. This was because of the much tighter fit of the shank and receiver back then. Bet one couldn't do that with today sloppy fit! I wouldn't want to drive 5 miles without the pin, let alone 500. Hope putting the pin in is never overlooked or the angel clip as well.
Cheers, John

Considering that my hitch weighs about 100lbs with the mud flaps attached to it and I don't have a place to store it when it is not on the truck, I end up leaving it on there. The mud flaps also protect drivers behind me from rocks. It is also rude to park your Prius so it takes up more space than my Excursion. The hitch also serves to discourage rude tailgaters.
It is also rude to drive 60 on an interstate and block traffic. Rude is the new normal these days, where have you been?

Take a look at HitchRider.com. They have a hitch vise that works great. 30 bucks.

I welded a piece of thin steel to the side of mine and filed it to fit.

I would be worried about so much slop that is bends the pin. That is not a normal amount of slop and I think that warrants a new receiver being installed. Welding these receivers makes me a little worried about changing the properties of the metal. I have gone so far as to weld a nut to a receiver extension and then using a bolt to take up the slack. This was used on an extension piece that held some steps for a slide in camper. The modified piece was not used to pull a trailer.

I resemble that remark.
Right now it is out. But when we leave for the summer it will probably be in until we get back in October. Stay well clear of the back of "giant pick up trucks".

Insurance cos. will have field day if leaving hitch on and doing damage plus so will cops, or causing personal injury.

Yep, I have been using beer can shims to seal the pipes on Ironhead heads for years.

I drink my IPA out of bottles
I think we have so 7 up cans, I'll try cutting a some strips to see how it works.

What about side to side stinger movement?

IPA, yup good stuff. Aluminum shims, me thinks too soft to hold up.

My aluminum shims were too soft and got beat thin in about one trip. I went to Home Depot and got some Simpson Strong Ties metal mending plates for under a buck. They are steel and seem to hold up much better. One thickness shim on the bottom and one on the side seems to take all the slop out of my hitch system. My hitch receiver is on a Jeep Grand Cherokee, 2012.
I have an Andersen hitch system. When I was at the Andersen plant in Idaho Falls, ID they told me that they buy the shank shaft material pre made and have no actual control over it's dimensions. They indicated it is a standard stock industrial metal product. They said that many of the receivers built seem to be oversized and of course they also have no control whatsoever about the receiver socket size which comes on the rigs as delivered to the customer.
I don't recall this being a problem in the "old days" but seems to be common now.

I found some flat washers in my parts bins but they were too thick. How thick are the Simpson Strong Ties?
