How to Install a Trailer Hitch on a 2013 Toyota Tundra


Today on our 2013 Toyota Tundra we're going to review and install the CURT class five 2" receiver tube hitch, part number C15398. Now here's what our hitch is going to look like once it's installed. The CURT Extra Duty has got a really large square crosstube. It's a completely steel and fully welded design. It's got a really nice black powder-coated finish to resist that rust and corrosion that can build up over time. On each side of our receiver tube is large chain hold downs.

This is a class five 2" by 2" receiver tube, and it has a pre-drilled 5/8 pinhole. The hitch itself is capable of up to 2,400 pounds of tongue weight and a 16,000 pound tow capacity. When coupled with a weight distribution hitch, you can do up to 2,400 pound of tongue weight and 17,000 pound tow capacity. Next we'll go ahead and give you a couple measurements to assist you with selecting accessories for your new hitch. From the center of the hitch pinhole to the outermost edge of the bumper is 2". From the top of the receiver tube opening down to the ground is 17-1/2".

This will assist you with selecting accessories such as a ball mount, bike rack, or cargo carrier. Next we'll go ahead and show you the minimum tools required for installing the hitch. We've got our 1/2" nylon tube brush and spray lubricant; 17mm, 19mm, 3/4", and 7/8" sockets; extension; 13/16 wrench; ratchet, and torque wrench. Now we'll go ahead and show you how easy it is to install the hitch. To begin our install we need to remove a few of the manufacturer's fasteners. Now keep in mind, our attachment points and hardware are the same on both sides so each process we do here to the passenger side is going to get repeated identically on the driver side. To begin our install we need to remove the manufacturer's l-bracket that secures the frame to the bumper bracket.

There are a total of four fasteners, two that go through the side and two through the bottom. Now we'll hang onto these fasteners as they'll be reused to secure the hitch. Again, we're going to hang onto the bolts but set the l-bracket aside as it will not be reinstalled. Now we've removed the manufacturer's four fasteners. We're going to reuse the manufacturer's 12mm bolt only we're going to add a 1/2" conical tooth washer that will go through the attachment point of the hitch and back into the manufacturer's weld nut. Our side two fasteners we'll install a new 9/16 bolt and conical tooth washer going through the hitch, through the side bracket, and securing it with a 9/16 flange nut on the outside.

We're now ready to go ahead and install our hitch. It's a good idea to get an extra set of hands to help you hold the hitch while you install your fasteners. Keep in mind as we install our fasteners we'll install each one finger tight until they're all in place. Next we'll go ahead and point out the hitch side bracket attachment points. We'll have two here at the pre-drilled holes or attachment points in our hitch. Each of those attachment points is going to get a 1/2" carriage bolt, go through the hitch side bracket, then through the hitch, and get secured with a 1/2" flange nut. The other two hitch side bracket attachment points are going to go up to the side of the frame and reuse the manufacturer's weld nuts. The hardware for these attachment points will be reusing the manufacturer's 14mm bolt we previously removed, along with a 9/16 conical tooth washer that will go through the hitch side bracket and into the weld nut. Now before we attempt to install the hardware, we're going to want to clean out the weld nut because over time they're going to build up with rust, dust, dirt and debris. Now to clean out the manufacturer's weld nuts we're going to use a spray lubricant and our 1/2" nylon tube brush, part number 814092. We'll take the tube brush and thoroughly clean out the weld nuts before we attempt to install our fasteners. Then once we have it cleaned out we can go ahead and take one of the bolts, thread it into the weld nut to make sure that it will go nice and easily. Now with the first of the manufacturer's weld nuts cleaned out, I'll go ahead and repeat the same process for the other three. We're now ready to install our hitch side bracket. We'll go ahead and put the side bracket up into place, start installing our fasteners. Again, keep in mind as we install our fasteners we'll install each one finger tight until they're all in place. Now once we have all our hardware in place we're ready to go ahead and tighten it down. Keep in mind, we'll tighten and torque in the manufacturer's recommended order and specifications, starting with the manufacturer's 12mm bolts first. Next we'll tighten down our 14mm bolts. Then we'll tighten down the 9/16 hardware. Now once we have all our fasteners tightened down, we'll go ahead and torque to specifications following the same tightening sequence. Now with our hitch installed and tightened down and torqued to specifications, we're ready to hit the road. That will do it for the review and install of the CURT Extra Duty class five 2" receiver tube hitch, part number C15398, on our 2013 Toyota Tundra.
