The correct adjustment of a sway bar, also known as an anti-sway bar, on a travel trailer is crucial for maintaining stability and control while towing, preventing dangerous fishtailing and ensuring a safe and enjoyable journey. The process primarily involves ensuring the correct tension on the friction pads (for friction sway control) or proper positioning and tightness of the cams (for weight distribution hitches with integrated sway control), according to the manufacturer’s specifications, which often vary significantly between models.
Understanding the Importance of Sway Control
Sway, the uncontrolled side-to-side movement of a trailer, can be a terrifying and dangerous experience. It often arises from external factors like strong crosswinds, passing trucks, uneven road surfaces, or even improper loading within the trailer. A properly adjusted sway bar acts as a mechanical counterforce, resisting these lateral movements and keeping the trailer aligned with the tow vehicle. Without adequate sway control, even minor disturbances can escalate into a runaway situation, potentially leading to accidents.
The type of sway control you have will determine the exact adjustment procedures. We’ll cover both common types here: friction sway control and weight distribution hitches with integrated sway control.
Adjusting Friction Sway Control
Friction sway control systems are often simpler and less expensive than weight distribution systems. They work by applying friction to resist the pivoting motion between the tow vehicle and the trailer. Here’s how to adjust them:
Step 1: Identifying Your System
Friction sway control systems typically consist of a ball mount on the trailer A-frame and a corresponding ball mount on the tow vehicle’s hitch receiver. A telescoping friction bar connects these two ball mounts. It’s vital to identify the specific model of your sway bar, as adjustment recommendations can vary.
Step 2: Initial Setup and Leveling
Before adjusting the sway bar, ensure your tow vehicle and trailer are properly hitched and leveled. This often involves adjusting the ball mount height on your tow vehicle to achieve a level trailer. This step is critical because incorrect leveling can negatively impact the effectiveness of the sway control.
Step 3: Adjusting the Tension
The key to adjusting a friction sway control is setting the proper tension on the friction pads inside the telescoping bar. Most models use a lever or tightening knob to increase or decrease this tension.
- Increasing Tension: Turn the lever or knob clockwise to increase tension. This makes the system more resistant to sway. Start with a moderate setting and gradually increase it as needed.
- Decreasing Tension: Turn the lever or knob counterclockwise to decrease tension. This allows for more freedom of movement between the tow vehicle and trailer. Reduce tension if you experience jerky movements or difficulty making turns.
Step 4: Testing and Fine-Tuning
After making an adjustment, test drive the setup in a controlled environment, such as an empty parking lot. Observe how the trailer behaves during turns and simulated emergency maneuvers. Fine-tune the tension until you achieve a smooth and stable towing experience. Remember to decrease the tension when maneuvering in tight spaces, such as campgrounds, to avoid excessive strain on the system.
Step 5: Regular Maintenance
Regular maintenance is essential for ensuring the longevity and effectiveness of your friction sway control system. Lubricate the ball mounts and friction bar periodically with a light grease or spray lubricant. Inspect the friction pads for wear and replace them as needed.
Adjusting Weight Distribution Hitches with Integrated Sway Control
Weight distribution hitches redistribute weight from the rear axle of the tow vehicle to the front axle and the trailer axles, improving handling and braking. Many of these hitches also incorporate sway control, often using cams or similar mechanisms.
Step 1: Identifying Your System
Weight distribution hitches with integrated sway control come in various designs, so it’s crucial to identify your specific model and consult the manufacturer’s instructions. Common brands include Equal-i-zer, Blue Ox SwayPro, and Reese Dual Cam.
Step 2: Initial Setup and Weight Distribution
Before adjusting the sway control, ensure the weight distribution portion of the hitch is properly set up. This involves measuring the height of the tow vehicle’s front and rear fenders with and without the trailer attached. Adjust the spring bars or chains to return the front fender height to approximately its unhitched position. Proper weight distribution is essential for optimal sway control.
Step 3: Adjusting the Sway Control Mechanism
The sway control mechanism on these hitches typically involves adjusting the tension on the cams or other components that resist lateral movement.
- Cam Systems: For cam systems, ensure the cams are properly seated in their receptacles and that the L-brackets are securely attached to the trailer A-frame. Adjust the angle of the L-brackets or the tension on the spring bars to increase or decrease sway control.
- Other Systems: Follow the manufacturer’s instructions for adjusting the specific sway control mechanism on your hitch. This may involve tightening bolts, adjusting friction settings, or repositioning components.
Step 4: Testing and Fine-Tuning
After adjusting the sway control, test drive the setup in a controlled environment. Pay attention to how the trailer handles during turns, lane changes, and when encountering crosswinds. Fine-tune the adjustments until you achieve a stable and controlled towing experience.
Step 5: Regular Maintenance
Regularly inspect all components of the weight distribution hitch and sway control system for wear and tear. Lubricate the moving parts, such as the cams and ball mounts, with a suitable grease. Tighten any loose bolts or fasteners.
Important Considerations for All Sway Control Systems
- Read the Manufacturer’s Instructions: This cannot be stressed enough. Each sway control system is different, and following the manufacturer’s recommendations is paramount for safety and performance.
- Proper Loading: Ensure your trailer is loaded properly, with approximately 60% of the cargo weight located in the front half of the trailer. Improper loading can exacerbate sway problems.
- Tire Pressure: Maintain proper tire pressure on both the tow vehicle and the trailer. Underinflated tires can contribute to sway.
- Driving Speed: Reduce your speed when towing in windy conditions or on uneven roads. Excessive speed can increase the risk of sway.
- Regular Inspections: Inspect your sway control system regularly for wear and tear. Replace worn or damaged components immediately.
- Professional Installation: If you’re unsure about installing or adjusting a sway control system, seek the assistance of a qualified professional.
Frequently Asked Questions (FAQs)
1. What happens if my sway bar is adjusted too tightly?
An over-tightened friction sway control can create a stiff and jerky ride, making it difficult to maneuver in tight spaces and potentially stressing the system components. With weight distribution hitches, excessive tension can lead to binding and reduced turning radius.
2. What happens if my sway bar is adjusted too loosely?
If the sway bar is too loose, it won’t effectively resist lateral movement, and you’ll experience excessive sway, especially in windy conditions or when encountering passing trucks. This significantly increases the risk of losing control.
