  • Bent Receiver Pin - Heads Up!

    I thought I would share my findings in a separate post incase anyone else is looking for this information. Now to be honest, I am sure several people will read this and say, "Well duh!" However, I didn't think about this, so I am going to assume there is at least one other person out there that hasn't as well, and that they should see this. At least, that's what will help me sleep tonight

    Anyways, after reading the post https://gdrvowners.com/towing-and-hi...owing-accident and reading Jlawles2 post about a bent hitch pin, I thought I would check my receiver pin. What I found is in picture 1. As you can see, it has a slight bend to it. I was trying to figure out what was causing this and nothing was immediately coming to mind. While I thought it over, I figured I would take the time and paint over the rust spots on my hitch receiver on the TV, and while doing that I found the what you can see in photos 2 and 3, with the slight deformation in the receiver. This lines up perfectly with the shank on my WDH, and it became clear to me.

    When backing in our trailer into the driveway to load up and go camping, I haven't been undoing the WDH bars. Meaning they are trying to keep the trailer and truck 'aligned', meaning the hitch shank would be pushing down on the receiver, causing the slight deformation and bent pin. So, let this be a heads-up if you need it, undo your WDH bars when backing up an incline, or on a sharp corner for that matter, and check your receivers and hitch pins.

    I checked the receiver over closely, and I don't see any cracks. The shank itself is true and not bent, and when inserted into the receiver the pin hole lines up. Obviously I will be picking up a new pin, changing my load up procedures, and looking much closer to how much play the WDH shank has relative to the receiver. IE, if the shank is much smaller than the receiver, that to me would mean the shank is concentrating it's force onto a small point in the receiver, pivoting about the receiver pin.

    Stay safe everyone, and if you want to shame me, go ahead

      you might try a hitch tightener such as MAXXHAUL 50023 anti rattle clamp. i think less than 10 bucks probably amazon. used it to take the slop out of towbar tongue in another lifetime.

        Yea that was what I was thinking. Hitch tightener or hitch stabilizer (same product, different name). They bolt on and keeps your hitch from moving around within the receiver. The idea of having to remove your bars for certain maneuvers is a no go to me.

        Coincidentally I have a receiver bike rack that arrived today. After seeing the slop in the receiver I ordered a hitch stabilizer off of Amazon just a couple of hours ago. Should deliver Friday. $15.99.

          StephenO -- no "shame" in posting what an owner learns (sometimes the hard way). I'd be first in line for "prose abuse" if that was the case.

          As the others have mentioned, an anti-rattle device may help with the issue as shared in post 8 of the referenced thread: https://gdrvowners.com/towing-and-hi...7474#post57474

            StephenO I would be interested in what brand WDH you have that might cause a problem when backing or maneuvering?

              flyfshrockies - Great question Dave, and I guess I should start off by clarifying that I don't think I caused this issue in the receiver by reverse maneuvering. I had just always heard that if you are making any really tight turns when backing up, that it's advisable to undo the WDH bars. The indentation on the receiver and bent pin, I am sure was caused by leaving the bars engaged while parked on my driveway. IE, as the bars tried to keep the trailer and truck aligned, they were pulling up the truck rear end, which put downwards pressure on the receiver and pin. I should also add that when parked on my driveway, the trailer would be on the incline and the truck would stay on the level road. Our driveway is unfortunately not long enough for both!

              Anyways, I just have the EAZ-lift WDH, which I believe is manufactured by Camco? It was the hitch provided by our dealer, and at the time of purchase, the emotions of buying a new toy got to me and I didn't think to look at an upgrade. The thought of upgrading my hitch to one with built in away control has come to mind, especially when towing in the wind!

              Great username BTW, where is your secret fishing spot?

                StephenO You can see the deformation on the left bottom side of the pin from impact loading. There is a tolerance issue that is causing the pounding on the left side on the pin. Check the tolerance on your hitch pin opening, and the 2" opening and the stinger on the hitch.

                Thinking your stinger (EAZ WD Hitch) or your receiver is not cross drilled straight where the impact loading is being applied to one side of the pin rather than the entire pin, hitch and receiver. All the impact loading is being applied to this one side. Also remember a pin cannot bend if the tolerances are tight enough to not allow bending. Even with impact loading. Is your stinger solid steel?

                  Guest Great info, thanks Jim! I'm assuming by stinger, you are referring to the adjustable shank? IE, the part that goes into the receiver? I'll check all those tolerances though and measure to check if everything is aligning as expected, and that there isn't too much play in there In terms of material used on the stinger (again, assuming shank) I am not 100% sure but I'll see if I can find that info.

                  Thanks again!

                    Correct, I am referring to the shank as the stinger. Poor word choice on my part. If the pin is not horizontal and as others have stated, where you have a great deal of play in the system while inserted in the receiver, it is perceivable that the motion in the receiver is taken up by one side on the pin and is being impacted. Can you take a pic of the inside of your receiver with a new pin installed? A pic of the pin sitting on the bottom of the hole and again with pin pushed up into the horizontal drilling? Then again with the new pin installed in the shank.

                      It must be one of those Canada vs US terms . No problem, I'll get some pictures..... once I pickup a new pin

                        I want to follow up on this thread. I just checked my locking pin and it was in great shape after 25,000+ miles and nearly five years. So I have some follow up questions:

                        1. What class is your receiver?
                        2. What is the hole size on the receiver and shank?
                        3. What is the diameter of the bent pin?

                        My Truck has a class V receiver that has a 5/8" hole size. My Blue Ox shank has a 5/8" hole size. My locking pin from deadboltlocks.com is 5/8".

                        If you're using a 1/2" pin in a system that is set up for 5/8", it may be what's causing the bend.

                        Here is the brand of locking pin I'm using:

                          Hey TucsonJim, to answer your questions:

                          1. What class is your receiver?
                          Class IV
                          2. What is the hole size on the receiver and shank?
                          Both the receiver and shank are a nominal 2", which corresponds to the class of the receiver. I measured both and the receiver is 2-1/16" square and the shank is 2" square.

                          3. What is the diameter of the bent pin?
                          The bent pin, receiver and hitch shank are 5/8" in diameter and I confirmed those by measuring.

                          Some other measurements I took are:
                          - The shank is 11" long
                          - The hitch is 15-3/4" overall in length
                          - The front of the pin hole on the shank is set back 2" from the tip
                          (Our shank is not square on the end, it comes to a point tapered side to side). You can see the profile of the shank in the deformation on the receiver (Photos 2 and 3 above)
                          - I inserted the wdh into the truck and pinned it. I then measured from a single point on the hitch head to the ground two times, once with me lifting straight up, and another letting it rest. Subtracting those two vales gave me approximately 1/2".
                          - Leaving the hitch head on the TV, I estimated I could move the wdh side to side again about 1/2"

                          Happy to answer any other questions and I really appreciate everyone's thoughts here. I still intend on getting some pictures and measurements of the pin holes on the receiver and shank once I pickup a new pin.

                          At the end of the day TBH, I just hope I didn't damage my receiver or trailer frame with leaving the wdh bars engaged when I parked on the driveway to load up.

                          Thanks again

                            Dang it. I was hoping you had a 1/2" pin and you could remedy everything by just using a 5/8" pin. But you already are. Shucks.

                              My gut is still telling me the pin was bent when I had the bars engaged and parked the trailer on the inclined driveway while the truck was on the level ground. IE, the bars were lifting the hitch head, causing a downwards force on the tip of the shank, which also lifted up on the hitch pin since there is that play between the receiver and the shank. However, I barely passed my statics and dynamics courses back in the day so I could be way out to lunch
