Adding a trailer hitch to your car or truck allows you to tow anything from a bike rack to a luxury camper. Whether you drive a small crossover, a full-size SUV, or a heavy-duty pickup truck, there’s a hitch class designed to match your towing capacity and trailer weight.
Installing a hitch is a straightforward DIY project if you have a few basic tools and a little automotive know-how. Here, we cover how to install a hitch, from choosing the right hitch class to installing the hitch and ball mount.
How to Install a Hitch
Here’s a step-by-step guide to installing a hitch on your vehicle.
1. Understand the Types of Hitches
The first step in this project is determining the type of hitch you need based on your vehicle’s towing capacity and what you plan to tow. Here’s a breakdown of common hitch types:
A bumper hitch mounts onto the bumper of an SUV or pickup truck. It provides a receiver tube suitable for light towing tasks, such as a bike rack or cargo carrier. Depending on the model, bumper hitches may support 3,500–5,000 pounds of weight.
Fifth-wheel hitches mount onto the bed of a pickup truck and accept the kingpin of a fifth-wheel trailer, similar to a tractor-trailer coupler. These heavy-duty hitches can support 16,000–30,000 pounds and work best for recreational towing.
A front-mount hitch attaches to the front of a pickup truck or SUV. It provides a standard receiver tube suitable for a snow plow, cargo carrier, or winch mount. Front-mount hitches may support 3,000–5,000 pounds.
Gooseneck hitches mount onto the bed of a pickup truck with a ball that couples with gooseneck trailers. They are minimally invasive and easier to remove than fifth-wheel hitches. They can support 25,000–32,500 pounds and work best for farm and commercial towing.
A pintle hitch can be mounted directly onto a vehicle frame or attached to an existing receiver hitch. It provides a hook that matches the lunette ring commonly found on military, agricultural, and industrial trailers. Pintle hitches are only available for heavy-duty vehicles and can handle up to 60,000 pounds, depending on the model.
Rear receiver hitches are the most common and versatile type of hitch. They are available in five classes with various receiver sizes and weight limits ranging from 2,000 to 20,000 pounds. Almost all vehicles, including small crossovers and some cars, can support a rear receiver hitch.
A weight distribution hitch attaches to the hitch receiver on an SUV or pickup. It helps level the vehicle and trailer, evenly distributes the tongue weight, and increases the hitch receiver’s weight capacity. Weight distribution hitches can handle 5,000–15,000 pounds of weight.
2. Determine Your Vehicle’s Towing Capacity
Every vehicle has a maximum amount of weight it can safely tow, which is usually outlined in the owner’s manual or on a label inside the driver-side door jamb. Most manufacturers also post this information on their websites. It’s important not to exceed your vehicle’s towing capacity, which could compromise your safety, cause mechanical damage, and void the manufacturer’s warranty.
Consider a few factors when selecting a compatible hitch and trailer:
- Curb weight: How much your vehicle weighs without any passengers or cargo
- Payload: The total weight of any cargo and passengers in your vehicle, including the tongue weight
- Tongue weight: The downward force exerted on the back of the vehicle by whatever it is towing, which counts toward the payload
- Towing capacity: The maximum amount of weight your vehicle can tow, including the trailer weight and payload
- Trailer GVWR: The gross vehicle weight rating, or maximum loaded weight, of the trailer
- Trailer weight: How much the trailer weighs without any cargo
- Vehicle GCWR: The gross combined weight rating of the vehicle, or the maximum amount it can weigh when loaded with cargo or towing a trailer
- Vehicle GVWR: The gross vehicle weight rating, or maximum loaded weight, of your vehicle
Compare your vehicle’s weight ratings against the gross weight of whatever you plan to tow. Then, select a hitch class and type that aligns with those limits and requirements. Subtract your vehicle’s curb weight and payload from the manufacturer-prescribed GCWR to yield your towing capacity.
Your vehicle’s GCWR should be greater than your vehicle’s curb weight plus the trailer weight and any payload. The vehicle payload, including the tongue weight of your trailer, should not exceed your vehicle’s GVWR, nor should the weight of the trailer and its payload exceed your vehicle’s towing capacity.
3. Gather Tools
Once you understand your vehicle’s towing capacity and the type of hitch you need, you can start gathering the tools required for installation. Basic tools typically required for this job include the following:
- Hitch kit
- Jack stands
- Ratchet and socket set
- Ratchet extension
- Safety glasses
- Shop light
- Swivel socket
- Torque wrench
- Vehicle jack
- Wheel chocks
- Work gloves
4. Chock Your Wheels and Jack Up Your Vehicle
The first step in the physical installation process is to activate the parking brake and chock your front wheels. Wheel chocks keep you safe by preventing your vehicle from moving while you are working underneath it.
Most hitches can be installed with all four wheels on the ground, but jacking up the back will give you extra clearance to work comfortably under your vehicle. If you go this route, use jack stands to stabilize your vehicle.
5. Remove the Spare Tire
Remove your vehicle’s spare tire if it’s underneath or near the point at which you plan to install your hitch. This will clear space and provide easy access to the vehicle’s frame and mounting points.
6. Remove Bolts, Plugs, and Other Parts
You may need to remove some bolts and plugs to align and attach the hitch properly. You may also need to remove or trim other components, such as a panel or heat shield. Keep track of any parts you remove so you can replace them later if necessary.
7. Clean Thoroughly
Exposure to outdoor elements, such as dirt, mud, rainwater, and rock salt, can leave the underbody of your vehicle dirty or corroded. Begin hitch installation only after cleaning this area thoroughly. Dirt, rust, or debris can affect how well the hitch fits and functions.
Importance of Cleaning Weld Nuts
Weld nuts are built into the frame and hold the bolts that secure the hitch. Any rust or dirt here could compromise the integrity of the installation or lead to a malfunction down the road, so clean weld nuts and their surrounding area thoroughly. A wire brush and penetrating lubricant are enough to remove minor rust, but you may need a thread-cleaning tap for heavier deposits.
8. Position the Hitch and Attach Hardware
Align your hitch with the mounting site before attaching any hardware to ensure that all bolts and fixtures fit. Incorrect alignment could make the hitch unstable or cause problems when it’s time to attach your trailer. Once the hitch is in place, secure it using the included bolts, nuts, and spacers. Hand-tighten the bolts as you go.
Fish-Wiring Bolts Through the Frame
If the installation requires you to feed bolts through areas that are not easily accessible, pass the coiled end of a fish-wire tool through the mounting hole, access hole, and hitch. Install a spacer on the end and thread the bolt onto the coil. Pull the other end of the fish-wire back through the mounting hole to guide the bolt into position, and secure the bolt with a nut.
Reverse Fish-Wiring Bolts
Reverse fish-wiring involves threading the bolt onto the coiled end of the fish-wire, then inserting it into the mounting hole head-first. If the hole is not large enough for the bolt to pass through, you can use a die grinder to enlarge it.
Next, feed the wire through a spacer, place the spacer in the mounting hole, and pull the wire down so that the bolt stud passes through the spacer and out the mounting hole. The spacer should hold the bolt head in place.
Finish by feeding the fish wire through the appropriate hole on the hitch, removing the fish wire from the bolt, and securing the bolt with a nut.
Temporarily Lowering the Exhaust
Some hitches require lowering the tailpipe and part of the exhaust assembly. You can do this by supporting the exhaust with heavy-duty wire ties and leaving a few inches of slack so you can lower the exhaust. Apply lubricant or soapy water to the connection points, then separate the rubber isolators from the hanger straps.
Drilling Into the Frame
You may need to drill into the frame to attach the hitch if your vehicle does not have existing mounting holes. Use the hitch as a guide to determine where to drill, then mark each spot with a paint pen. Drill a small pilot hole using a carbide drill bit and cutting lubricant. Enlarge the hole with increasingly larger drill bits until it is the proper size.
Trimming Vehicle Fascia
You may need to trim the vehicle fascia to make room for the hitch receiver. Use masking tape to mark your cut lines, then trim the fascia with a utility knife, aviator shears, or a rotary cutoff tool.
9. Fully Tighten the Bolts
Once all of the hardware is in place, use a torque wrench to fully tighten the bolts. Follow the manufacturer’s instructions carefully to achieve a secure installation.
10. Install the Ball Mount or Trailer Ball
After the hitch is securely attached, you can install the ball mount or hitch ball, which connects your vehicle to whatever you are towing. Make sure it is tightly secured and properly aligned with the hitch receiver.
Changing Ball Size
You may need to switch out the ball on your hitch if you plan to tow different types of trailers. Changing the ball size usually involves loosening the nuts under the hitch ball, removing the old ball, and installing the new one. You can invest in multi-ball mounts that you can easily rotate.
Our Conclusion
Installing a hitch yourself is a straightforward DIY project as long as you follow the manufacturer’s guidelines carefully. If you are unsure about any step, consider professional installation. Whether you’re looking to lower your moving costs or spend more time outdoors fishing, biking, or camping, a properly installed hitch offers utility and freedom.
