This manual provides detailed instructions for the proper installation, operation, and maintenance of your CURT 17422 Short Trunnion Bar Weight Distribution Hitch with Sway Control. This specialized towing system is designed to enhance vehicle and trailer control by distributing the trailer's tongue weight more evenly across the vehicle's and trailer's axles, promoting a level towing experience. It is suitable for travel trailers, campers, and other large loads, with a gross trailer weight capacity up to 15,000 lbs. and a tongue weight capacity of 1,500 lbs.
The integrated sway control unit further assists in limiting lateral trailer movement, contributing to a more stable towing experience. Please read this manual thoroughly before installation and use to ensure safe and effective operation.

การติดตั้งและการตั้งค่า
Proper installation is crucial for the safe and effective operation of your weight distribution hitch. It is recommended that installation be performed by a qualified technician if you are unfamiliar with towing equipment.
เครื่องมือที่จำเป็น:
- ประแจแรงบิด
- Sockets and Wrenches (various sizes)
- สายวัด
- ระดับ
- Grease Gun (for lubrication)
ขั้นตอนการติดตั้ง:
- เตรียมรถและรถพ่วง: Park the tow vehicle and trailer on a level surface. Ensure the trailer is loaded as it would be for travel. Level the trailer using its tongue jack. Measure and record the height of the front and rear bumper of the tow vehicle, and the height of the trailer coupler.
- Install Shank: Insert the 2-inch shank into your vehicle's receiver hitch. The shank can be flipped to provide the necessary drop or rise to achieve a level trailer. Secure with a hitch pin and clip.
- Attach Head Assembly: Slide the weight distribution head assembly onto the shank. The head features a pre-torqued 2-5/16-inch trailer ball. Adjust the tilt of the head to allow for proper spring bar tension.
- ติดตั้งสปริงบาร์: Insert the trunnion-style spring bars into the head assembly. Ensure they are fully seated and secured with the retaining pins.
- Mount Hook-up Brackets: Position the hook-up brackets on the trailer frame, typically 28-32 inches back from the center of the coupler. Secure them firmly.
- Connect Spring Bar Chains: Attach the spring bar safety chains to the ends of the spring bars and then to the hook-up brackets. Use the lift handle to raise the spring bars and engage the chains onto the brackets, ensuring the trailer is level and the vehicle's front and rear bumper heights are restored to their original measurements (or slightly lower at the rear). Adjust chain links as needed to achieve proper tension.
- Install Sway Control Unit: Mount the sway control unit to the trailer frame and the hitch head using the provided hardware. Ensure the unit is positioned to allow full articulation without interference. The spacer plate helps ensure proper alignment.
- การตรวจสอบขั้นสุดท้าย: Double-check all connections, bolts, and pins. Ensure the trailer is level and the tow vehicle's suspension is properly loaded.

การแก้ไขปัญหา
| ปัญหา | สาเหตุที่เป็นไปได้ | สารละลาย |
|---|---|---|
| Trailer not level / Vehicle sagging | Insufficient spring bar tension; incorrect head tilt; overloaded trailer. | Increase spring bar tension by adjusting chain links; adjust head tilt; ensure trailer is not overloaded. |
| Excessive trailer sway | Sway control not engaged; improper weight distribution; incorrect tire pressure; excessive speed. | Ensure sway control is properly connected and adjusted; verify weight distribution settings; check tire pressures; reduce towing speed. |
| Noisy operation (e.g., creaking, groaning) | Lack of lubrication on pivot points or sway control friction surfaces; loose components. | Lubricate hitch ball, spring bar pivot points, and sway control unit; inspect and tighten all fasteners. |
| Difficulty engaging/disengaging spring bars | Too much tension; vehicle/trailer not level. | Use the trailer tongue jack to raise the trailer coupler slightly, relieving tension on the spring bars before engaging/disengaging. |
