Tools and Materials Required for Installation

The installation process for CURT Class 3 trailer hitches typically requires the following tools and materials, as outlined in the official installation manuals:

17mm Socket Wrench: Used for tightening bolts. An extension may be necessary for vertical bolts.
Flathead Screwdriver (small-tipped): Required for removing plastic trim rivets from underbody panels.
WD-40 or Similar Lubricant: Useful for loosening exhaust hangers that may restrict clearance during installation.
Torque Wrench: Recommended for ensuring bolts are tightened to the manufacturer’s specifications (typically around 40 ft-lbs).
Safety Equipment: Safety glasses and gloves should be worn to prevent injury during installation.
Assistance: A second person is often necessary to help lift and align the hitch.

Some models may require additional tools depending on the vehicle. For example, the installation manual for the CURT 13200 for the Toyota Highlander includes instructions for lowering the exhaust system to provide clearance for the hitch. In such cases, it is important to follow the vehicle-specific steps provided in the manual.

Step-by-Step Installation Instructions

The installation process is similar across most CURT Class 3 trailer hitch models. Below is a general guide based on the instructions provided in the source documentation:

1. Prepare the Vehicle

Park the vehicle on a level surface.
For easier access, consider using ramps or a lift.
Turn off the engine and engage the parking brake.
If necessary, remove any plastic underbody panels using a small flathead screwdriver. These panels are typically held in place by plastic rivets and can be popped out with minimal force.

2. Adjust the Exhaust System (If Applicable)

Locate the rubber exhaust hangers.
Apply a lubricant such as WD-40 to the hangers.
Carefully slide the hangers off the metal rods to allow the exhaust to hang lower, providing clearance for the hitch.

3. Position the Hitch

With the help of an assistant, lift the trailer hitch into position.
Align the mounting holes on the hitch with the pre-drilled holes in the vehicle’s frame.

4. Secure the Hitch

Insert the provided bolts and washers into the mounting holes.
Begin by hand-tightening one bolt on each side to temporarily hold the hitch in place.
Once the hitch is aligned, insert and hand-tighten all remaining bolts.
Use a torque wrench to tighten the bolts to the manufacturer’s specified torque (typically around 40 ft-lbs). Always refer to the specific instructions included with your hitch.

5. Reassemble Vehicle Components

Slide the exhaust hangers back onto their metal rods.
Reinstall any removed plastic underbody panels.

6. Final Check

Verify that all bolts are securely tightened.
Ensure the hitch is properly seated and stable.
Double-check the hitch for any signs of misalignment or instability.

Connecting a Trailer

Once the hitch is installed, it is ready for use with appropriate towing accessories. The operating instructions emphasize the importance of adhering to the hitch’s and vehicle’s weight limits.

Connecting the Trailer

Attach Ball Mount: Insert the appropriate ball mount into the 2" x 2" receiver tube. Secure it with a hitch pin and clip.
Attach Trailer Coupler: Lower the trailer coupler onto the hitch ball. Ensure the coupler is fully seated and locked onto the ball.
Connect Safety Chains: Cross the trailer’s safety chains under the trailer tongue and attach them to the designated chain loops on the hitch or vehicle frame. This provides a backup connection in case the primary coupling fails.
Connect Electrical (If Applicable): If your trailer has lights or electric brakes, connect the trailer’s wiring harness to the vehicle’s towing electrical connector. Test all lights (running, brake, turn signals) before driving.

Safety and Towing Considerations

The CURT documentation repeatedly emphasizes the following safety points:

Do not exceed the hitch's GTW or TW limits, or the vehicle’s towing capacity, whichever is lower.
Always use safety chains when connecting a trailer.
Test all electrical connections before driving.
Never exceed the manufacturer’s recommended towing capacity for the vehicle.
Inspect the hitch regularly for signs of wear, corrosion, or damage.

The operating instructions also suggest checking the hitch’s condition before each towing trip and re-torquing bolts after the first 50 miles of use to ensure proper alignment and security.

Custom-Fit Design and Vehicle Compatibility

CURT trailer hitches are designed with a custom-fit approach for specific vehicle models. This ensures a precise fit and eliminates the need for drilling in most cases. For example, the CURT 13240 is designed for certain years of the Hyundai Tucson, while the CURT 13200 is tailored for select Toyota Highlander models. The documentation includes detailed compatibility information for various models, including:

Toyota RAV4 (2006–2023, excluding Electric)
Honda Pilot and Acura MDX
Volkswagen Golf R (2017–2023)
Chevrolet Equinox and GMC Terrain (2018–present)
Honda Odyssey

Each model has its own installation guide, often with vehicle-specific instructions, such as adjustments to the exhaust system or underbody panels. Users are advised to consult the model-specific installation manual to ensure a proper fit and installation.

Troubleshooting Common Installation Issues

While the installation process is generally straightforward, some common issues may arise:

Difficulty Aligning Mounting Holes: This can occur if the vehicle is not on a level surface. Ensure the vehicle is parked on a flat, stable area and use a second person to assist with alignment.
Tight Bolts or Hangers: Applying a lubricant like WD-40 can help loosen stubborn bolts or hangers.
Missing or Damaged Parts: Always check the contents of the hitch kit before beginning installation. If parts are missing or damaged, contact CURT’s product support.
Clearance Issues: If the hitch does not fit due to the exhaust system or underbody panels, refer to the vehicle-specific instructions for adjustments.

The documentation includes visual aids, such as diagrams and close-up images, to help users identify key components and installation steps. These visuals are particularly useful for identifying the 2" receiver tube, dual-coat finish, and mounting points.

Maintenance and Longevity

To ensure the longevity and performance of a CURT Class 3 trailer hitch, the following maintenance practices are recommended:

Regular Inspection: Check for signs of wear, corrosion, or damage before and after each towing trip.
Lubrication: Apply lubricant to bolts and hangers as needed to prevent seizing.
Cleaning: Clean the hitch regularly to remove dirt, road salt, or debris that could contribute to corrosion.
Retorquing: Retorque bolts after the first 50 miles of use to ensure proper alignment and tightness.

CURT’s dual-coat finish provides strong resistance to rust, scratching, and UV damage, but proper maintenance can further extend the hitch’s lifespan.
