Installation Overview
The installation of the CURT Class 3 Trailer Hitch is designed to be user-friendly, with many users able to complete the process using basic tools and a second person for assistance. The hitch is engineered to fit specific vehicle models, such as certain years of the Hyundai Tucson, and is constructed with a dual-coat finish process that includes a liquid Bonderite coating and a high-gloss black powder coat. The installation process does not require drilling in most cases, simplifying the setup and reducing the risk of damage to the vehicle.
Required Tools
The following tools are typically required for the installation of the CURT 13240 Class 3 Trailer Hitch:
- 17mm Socket Wrench (with an extension for vertical bolts)
- Flathead Screwdriver (small-tipped for plastic trim rivets)
- WD-40 or similar lubricant (for exhaust hangers)
It is important to ensure that all tools are in good working condition and that the user is familiar with their proper use. If any tools are missing or damaged, they should be replaced or repaired before beginning the installation process.
Step-by-Step Installation Instructions
Position the Hitch: Begin by positioning the hitch according to the vehicle-specific design. The hitch is designed to fit securely into pre-drilled or pre-fabricated mounting points on the vehicle’s frame, eliminating the need for additional drilling in most cases.
Secure the Mounting Bolts: Use the 17mm socket wrench to secure the mounting bolts through the hitch frame and into the vehicle’s frame. Ensure that the bolts are tightened to the manufacturer's specifications, typically listed in the product manual.
Reinstall Trim Components: After the hitch is mounted, reinstall any trim components that were removed during installation. A flathead screwdriver may be required to reattach plastic rivets or clips.
Lubricate Moving Parts: Apply a light coating of WD-40 or a similar lubricant to any exhaust hangers or other moving parts to ensure smooth operation and reduce the risk of corrosion.
Final Inspection and Torque Check: Once the hitch is installed, perform a final inspection to ensure that all bolts are securely tightened and that the hitch is properly seated. Use a torque wrench if available to confirm that all mounting bolts meet the specified torque values.
Clearance Check: Ensure that there is adequate clearance between the trailer and the vehicle, especially during turns. This helps prevent damage to both the vehicle and the hitch.
Operating Instructions
Once the CURT Class 3 Trailer Hitch is installed, it is ready for use with a variety of towing accessories. The hitch’s 2" x 2" receiver tube is compatible with standard ball mounts, hitch-mounted accessories, and other towing equipment. The following steps outline the proper procedure for connecting a trailer and using hitch-mounted accessories.
Connecting a Trailer
Attach the Ball Mount: Insert the appropriate ball mount into the 2" x 2" receiver tube. The ball mount should be selected based on the height of the trailer and the desired towing position. Secure the ball mount in place using a hitch pin and clip.
Attach the Trailer Coupler: Lower the trailer coupler onto the hitch ball. Ensure that the coupler is fully seated and locked onto the ball. A secure connection is essential for safe towing.
Verify Weight Capacity: Always ensure that the total weight of the trailer and its contents (GTW) does not exceed the hitch’s capacity or the vehicle’s towing capacity, whichever is lower. Similarly, ensure that the tongue weight (TW) is within the specified limits.
Check Clearance: Ensure that there is adequate clearance between the trailer and the vehicle, particularly during turns. This helps prevent damage to both the vehicle and the hitch.
Using Hitch-Mounted Accessories
For hitch-mounted accessories such as bike racks, cargo carriers, or trailer stabilizers, follow these steps:
Insert the Shank: Insert the accessory’s shank into the 2" x 2" receiver tube. The shank should fit snugly into the receiver.
Secure with a Hitch Pin and Clip: Use a hitch pin and clip to secure the accessory in place. Ensure that the pin is fully inserted and that the clip is properly engaged to prevent the accessory from becoming dislodged during use.
Verify Weight Capacity: Always ensure that the accessory is rated for the weight you intend to carry. Overloading an accessory can lead to failure and potential damage to the hitch or vehicle.
Check for Obstructions: Ensure that the accessory does not obstruct the vehicle’s lights or license plates. This is important for compliance with traffic laws and for ensuring visibility while driving.
Maintenance and Troubleshooting
Regular maintenance is essential to ensure the long-term performance and safety of the CURT Class 3 Trailer Hitch. The following maintenance steps should be performed periodically to keep the hitch in optimal condition.
Regular Inspection
- Inspect for Rust and Corrosion: Check the hitch for any signs of rust, corrosion, or damage. Pay particular attention to the welds, mounting points, and receiver tube.
- Check for Cracks or Deformation: Inspect the hitch for any cracks, bends, or other signs of structural damage. These can compromise the hitch’s strength and safety.
- Verify Bolt Tightness: Periodically check and re-torque all mounting bolts to ensure they remain secure. If bolts continue to loosen, consider using a thread-locking compound such as Loctite.
Cleaning and Lubrication
- Clean the Receiver Tube: Keep the receiver tube free of dirt, debris, and rust. A clean receiver tube ensures smooth insertion and removal of ball mounts and accessories.
- Lubricate Moving Parts: Apply a light coating of lubricant to any moving parts, such as the hitch pin or ball mount, to reduce friction and prevent corrosion.
Troubleshooting Common Issues
Loose Bolts:
- Cause: Bolts may become loose due to vibration or improper torque.
- Solution: Re-torque all mounting bolts to the specified value. If the issue persists, consider using a thread-locking compound on the bolt threads.
Excessive Noise or Rattling:
- Cause: A loose hitch pin, worn ball mount, or excessive play between the receiver and ball mount can cause rattling or noise.
- Solution: Ensure that the hitch pin is secure. If the play is excessive, consider using an anti-rattle device. Inspect the ball mount for wear and replace it if necessary.
Rust Formation:
- Cause: Exposure to elements such as road salt or moisture can lead to rust formation.
- Solution: Clean affected areas and remove loose rust with a wire brush. Apply a rust-inhibiting primer followed by a suitable paint or touch-up coating. Regular cleaning and waxing can help prevent further rust.
