Annoying Trailer Hitch, Here’s a Rattle Free Fix

Creating A Custom Form Fit Insert For Your Trailer Hitch Storage
I never thought that trailer hitch storage would be a problem. Yet I have found that my receiver hitch and hitch pin rattle around in the back of my vehicles. This is both annoying and distracting for reasons more than just its rattling. I neither want to leave the trailer hitch attached (I have had other ones effectively rust-weld themselves permanently in place) nor do I want to risk not having it available when I need it. So I first tried to store it under the trunk floor. That wasn’t an effective place for trailer hitch storage since it didn’t solve the rattling, even if it did give me more storage space.
Then I saw a post somewhere, it may have been Bethepro, about doing a custom form fit insert for your screw drivers in an L-BOXX-2 (or other brand equivalent). So I decided to try that as a new trailer hitch storage solution. In my first attempt I used a plastic garbage bag liner, and the very soft foam failed. Since I am stubborn I tried again, and after researching some more, I finally found a solution for my trailer hitch storage.
Rattling Trailer Hitch Storage Problems Solved
There were just a few general steps I solved to create a new trailer hitch storage in the trunk of my vehicle:
- I found an old sheet that my wife had relegated to a drop cloth and cut two roughly circular sections of it, one to line the wheel well of the spare tire and a second to cover the wet foam. It is important that the foam can breathe in order to cure properly so use cotton cloth, a sheet, T-shirt or whatever else seems to work best.
- Then I filled the lined well with a 68 0z. large can of Mono™ large gap expanding foam, shaking it vigorously every 30secs in order to get it all out and distributing it evenly by depositing the foam in concentric circles.
- I placed my second circle of sheet over top the foam and gently patted it down.
- Through trial and error, I determined that the foam needs to set up for at least 10 minutes to an hour prior to placing anything heavy on it. For me, I could temporarily place the hitch pin after 10-20 minutes, but if I left it would have sunk to the bottom, either trapping itself or touching the bottom and defeating the purpose.
- However, the receiver was too heavy no matter what, so I needed to suspend it in the foam without the foam having to carry the weight. What I ended up doing (on the fly, so others may have better ideas) was to suspend it from a wooden bar placed across the spare tire by using an old hard drive magnet screwed into the wood.
- I ended up giving the whole thing almost 24 hours to cure, then I trimmed one particularly large bubble of foam which may have touched the trunk cover.
- I placed the hitch and pin in their new homes and closed the liner, and it is working well so far. The whole trailer hitch storage system weighs only a few ounces / few hundred grams.
