How to Install the Curt Trailer Hitch on a 2021 Honda Odyssey


Hey everybody, how's it going Today we're gonna be showing you how to install the Curt Trailer Hitch Receiver here on our 2021 Honda Odyssey. So, this is what our trailer hitch is gonna look like installed. Now, we do have a visible cross tube here hanging below the bumper, but the reason I actually like the visible cross tube is because it doesn't require any modifications to the vehicle. A lot of the time we do have that concealed cross tube. We actually do have to do some cutting or trimming to the bottom of the bumper facia here, but we're not gonna have to do that, so, our vehicle is gonna remain stock. So, if we take a closer look at the trailer hitch, number one, we're gonna have this nice rounded collar on the outside of the receiver tube.

And then number two, we're gonna have a nice, shiny black powder-coated finish. It's gonna do a great job of help protecting our hitch from rust and corrosion. It's also gonna help it blend in with the vehicle really well. So, our trailer hitch is gonna allow us to do many different things, such as towing. Now, we have a class three capacity here, which is gonna provide us with a 3,500 pound gross trailer weight rating, which is the amount we can pull outward on the receiver tube.

We're also gonna have a 525 pound towing weight rating, which is gonna be the downward force on the receiver tube. Now, keep in mind, we actually can use this trailer hitch with a weight distribution system. If we do that, our gross trailer weight capacity is gonna increase to 5,000 pounds. However, I would like to point out that the trailer hitch and vehicle are tested separately of one another. So, the lower of the two ratings, in regards to weight capacity, is the one we're gonna have to abide by.

So, in addition to towing, we're also gonna be able to use our trailer hitch for bike racks and cargo carriers. Whether we wanna hit the trails, or free up some space inside the vehicle. We're gonna have an industry standard two inch by two inch receiver tube opening. And this is gonna give us plenty of bike racks and cargo carriers to choose from. Make sure you check out our selection here at etrailer.

So, on the side of the receiver tube we're gonna have our industry standard 5/8 inch diameter hitch pin hole, which will accept our standard 5/8 inch diameter hitch pin. So, I wanna make a note that this is actually gonna be sold separately. Most bike racks and cargo carriers will actually come with their own hitch pin. If you're using this for towing, and you're gonna be using a ball mount, chances are you're gonna need to pick one of these up. We have plenty of options here at etrailer. We have some locking ones as well. Now, on the bottom of the receiver tube, we're gonna have our welded-on safety chain tabs, and those are gonna be great for the larger clevis style hooks, as well as the smaller S-type. So, now we have a couple of measurements here for you. The distance from the ground to the top inside edge of the receiver tube. That'll be helpful when you're selecting your ball mount. That way you can make sure you can get the correct rise and drop to tow your trailer level. That measurement there is gonna be 13.5 inches. And then finally, we have the distance from the center of the hitch pin hole, to the outside edge of the bumper. That one's gonna be three and a half inches. And that'll be useful when you're selecting your folding accessories, such as a bike rack or cargo carrier. That way you can make sure while they're in the stowed position, that they don't contact the bumper. So, in regards to install, this one is pretty simple. Definitely something you guys can do at home by yourselves. We don't have to make any modifications to the vehicle, and we don't really need any specialized tools. So I definitely, again, think it's something you guys can do. Let's go ahead and walk you through that now. So, the first step of our installation we wanna come over here to the driver's side of the vehicle, underneath the bumper. And we're gonna be looking for a panel here. If present, your model may or may not have this. Ours does, so, we get to show you what it looks like, but here it is. We actually need to go ahead and remove this to install our trailer hitch. So, we're gonna have a few different types of fasteners holding this on. The first ones we have here are these little push pin fasteners. We're gonna get a trim panel tool, and we're gonna remove each of these. There's gonna be a couple along the outside edges here. We'll just simply take our tool, pry out the center section, we should be able to remove the rest completely. And then, if we come inside the wheel well liner here you're gonna see we have one Phillips head screw up here, that needs to come out as well. With that removed, we should be able to just pull our panel out. We can go ahead and set this aside. So, now we're gonna come over to the passenger side here. You're gonna see we have this little plastic exhaust deflector right above the tailpipe. There's gonna be two push pin fasteners we need to take out, cause we need to remove this as well. So, now we're gonna come to the outside here. We're gonna be looking at the bottom of the frame here, on either side. You need to do this on both. It doesn't matter which one you do first. We need to go ahead and feed our carriage bolt and our spacer block through this large access hole here. That's gonna be an attachment point for our hitch. Now, we're gonna be using a reverse fish wire technique to get our hardware into that. So, we're gonna take our fish wire here, we're gonna slip over our spacer block, and then we're gonna thread on our carriage bolt. Then we're going to shove the carriage bolt up into the frame, follow that up with our spacer block, and then just pull it straight down, like so. We repeat the same process on the other side. Now, directly beside that, we're gonna see we have two factory weld nuts in the frame here. Our hitch is gonna utilize these as well, using the provided hardware. It's gonna be a good idea to go ahead and clean these out beforehand. So, in order to do that, we can just take any sort of general purpose spray lubricant, spray that in there, and then sort of a wire brush to clean them out. If you want, you can actually take one of the bolts in your kit here, and you can just go ahead and thread that in to make sure there isn't gonna be any issues. So, now we're gonna go ahead and prep our hardware. So, on each side, we're gonna need one flange nut, and we're gonna need two of our hex bolts here, along with two of the conical tooth washers. We wanna make sure that, when we install the washer on the bolt, that the teeth are gonna be facing up towards the hitch. So, now we can take our trailer hitch here and go ahead and set it up on the vehicle. If you have an extra set of hands, that'll obviously be helpful for this next step here. But, what I'm gonna do, is I'm actually gonna do it by myself by supporting one end on the exhaust over here. So, we're gonna take our fish wire here, place it through that hole there in the rear, take one of our bolts. Once we get that one started, we'll go ahead and hop onto the other side there and get one of those in as well. So, now that we've got a bolt in on each side to hold it in place, we can begin installing the rest of our hardware here. And, for our carriage bolt here, we wanna make sure that when we're threading on the flange nut, that we put pressure on the side of the bolt. That way we don't push it back up into the frame. So, now let's go ahead and snug up all of our hardware here. We'll use a 19 millimeter socket on these two bolts. And this nut here, we'll use an 11/16. So, now we can come back with our torque wrench here, and torque everything down to spec. And don't forget, we need to re-install our little exhaust deflector here. So, in regards to our appearance panel here, we could simply leave this off. Or, if you wanted to re-install it, it really wouldn't be a big deal if you left it off. But, if you did wanna re-install it, you'd actually had to do some trimming here along this inside edge. We need to come inside here, come down a little bit. A good way to figure out how much you need to take out, is just to simply hold it up here, and maybe make an outline of where the flange is for your hitch, so you can see how much you need to trim. We're actually gonna be leaving it off on this vehicle here. And that's gonna do it today for our installation of the Curt Trailer Hitch Receiver here on our 2021 Honda Odyssey.
