• Never exceed the lowest weight capacity of any towing component, including the vehicle, hitch, and trailer. The CURT 40032 has a maximum gross trailer weight capacity of 3,500 lbs.
• Ensure all components are securely fastened and torqued to specifications before towing. Refer to the installation section for torque requirements.
• Regularly inspect the hitch ball for signs of wear, damage, or corrosion. Replace immediately if any issues are detected.
• This CURT tow ball is tested to U.S. VESC specifications to promote the highest level of safety while towing.

Setup and Installation

1. Verify Compatibility: Ensure the 1-7/8-inch ball diameter matches your trailer's coupler. Confirm your hitch ball mount has a 1-inch diameter hole for the shank.
2. Prepare Components: Gather the CURT 40032 hitch ball, zinc-plated hex nut, and helical lock washer.
3. Insert Shank: Insert the threaded shank of the hitch ball through the hole in your hitch ball mount.
4. Install Washer and Nut: Place the helical lock washer onto the shank, followed by the hex nut.
5. Tighten Securely: Tighten the hex nut to 250 lb.-ft. (foot-pounds) of torque. Use a torque wrench to ensure proper tightness. Insufficient torque can lead to loosening during towing, while excessive torque can damage the threads or components.
6. Final Check: Visually inspect the installation to ensure the hitch ball is firmly seated and the nut is securely tightened.

Operating Instructions

1. Connect Trailer: Carefully back your towing vehicle towards the trailer. Align the trailer coupler directly over the hitch ball.
2. Lower Coupler: Lower the trailer coupler onto the hitch ball. Ensure the coupler fully engages and locks onto the ball.
3. Secure Latch: Engage the coupler latch mechanism and insert any safety pins or clips as required by your trailer's design.
4. Attach Safety Chains: Cross the trailer's safety chains beneath the coupler and attach them to the designated points on your towing vehicle's hitch or frame. This prevents the trailer from separating completely if the primary connection fails.
5. Connect Wiring: Connect the trailer's electrical wiring harness to the towing vehicle's receptacle. Test all trailer lights (brake, turn signals, running lights) before driving.
6. Verify Load: Ensure the trailer load is properly distributed and does not exceed the maximum towing capacity of any component.

Maintenance

• Regular Inspection: Before each towing trip, inspect the hitch ball for any signs of wear, cracks, deformation, or excessive corrosion.
• Cleaning: Clean the hitch ball regularly, especially after exposure to road salt, dirt, or harsh weather conditions. Use a mild soap and water solution, then dry thoroughly.
• Lubrication: Apply a thin layer of grease to the hitch ball surface to reduce friction and wear between the ball and the trailer coupler.
• Storage: When not in use, store the hitch ball in a dry environment to prevent rust and corrosion, especially if removed from the vehicle.
• Replacement: If the chrome plating is significantly damaged, or if any structural integrity issues are observed, replace the hitch ball immediately.

Troubleshooting

Problem: Trailer coupler does not fit over the hitch ball.

Solution: Verify that the trailer ball diameter (1-7/8 inches) matches the coupler size. If they do not match, do not attempt to force the connection; acquire the correct size hitch ball.

Problem: Hitch ball appears loose after installation.

Solution: Re-check the torque on the hex nut. Ensure it is tightened to the specified 250 lb.-ft. If the threads are stripped, replace the hitch ball and nut assembly.

Problem: Rust or corrosion appearing on the hitch ball.

Solution: While the hitch ball has a chrome finish for protection, prolonged exposure to harsh elements without cleaning can lead to corrosion. Clean and lubricate regularly. If corrosion is severe and affects structural integrity, replace the ball.
