As a supplier of 6 car hauler trailers, I've encountered a wide range of common problems that customers often face. Troubleshooting these issues is crucial to ensure the smooth operation of the trailer and the safety of the transported vehicles. In this blog, I'll share some practical tips on how to troubleshoot these common problems.
Electrical System Issues
One of the most common problems with a 6 car hauler trailer is related to the electrical system. Faulty wiring, blown fuses, or malfunctioning lights can cause significant issues, especially during night-time transportation or in adverse weather conditions.
Blown Fuses
If you notice that some of the trailer lights are not working, the first thing to check is the fuses. Locate the fuse box, which is usually located near the trailer's electrical connection point. Carefully remove each fuse and inspect it for signs of damage. A blown fuse will have a broken wire inside. Replace any blown fuses with new ones of the same amperage rating. You can find the correct amperage rating in the trailer's user manual.
Faulty Wiring
Over time, the wiring in the trailer can become damaged due to wear and tear, exposure to the elements, or improper installation. To check for faulty wiring, start by visually inspecting the wires for any signs of fraying, cuts, or corrosion. Pay special attention to areas where the wires are exposed or prone to rubbing against other components. If you find any damaged wires, you'll need to repair or replace them. Use electrical tape or wire connectors to splice the wires together, making sure to follow the proper color-coding and wiring diagram.
Malfunctioning Lights
If the fuses and wiring are in good condition, but the lights still aren't working, the problem may lie with the lights themselves. Check the bulbs to see if they are burned out. Replace any burned-out bulbs with new ones of the same type and wattage. If the bulbs are fine, the issue could be with the light sockets or the switches. Inspect the sockets for any signs of damage or corrosion. Clean the sockets with a wire brush and apply a small amount of dielectric grease to prevent future corrosion. If the switches are not working properly, they may need to be replaced.
Brake System Problems
The brake system is another critical component of a 6 car hauler trailer. Any issues with the brakes can compromise the safety of the trailer and the vehicles being transported.
Brake Pad Wear
Regularly inspect the brake pads for wear. Over time, the brake pads will wear down due to friction, and eventually, they will need to be replaced. To check the brake pads, remove the wheel and visually inspect the pads. If the pads are less than 1/8 inch thick, it's time to replace them. You can find replacement brake pads at most auto parts stores. Make sure to choose brake pads that are compatible with your trailer's brake system.
Brake Fluid Leaks
A brake fluid leak can cause a significant loss of braking power. Check the brake fluid reservoir regularly to ensure that the fluid level is within the recommended range. If you notice a sudden drop in the fluid level, or if you see any signs of fluid leakage under the trailer, there may be a leak in the brake system. Inspect the brake lines, hoses, and calipers for any signs of damage or leakage. If you find a leak, you'll need to repair or replace the damaged component. It's important to address brake fluid leaks as soon as possible to avoid any safety issues.
Brake Adjustment
Proper brake adjustment is essential for optimal braking performance. Over time, the brakes may become out of adjustment, causing uneven braking or reduced braking power. To adjust the brakes, consult the trailer's user manual for specific instructions. In general, you'll need to use a brake adjustment tool to adjust the brake shoes or calipers. Make sure to adjust the brakes evenly on all wheels to ensure balanced braking.
Suspension System Issues
The suspension system of a 6 car hauler trailer helps to absorb shocks and vibrations, providing a smooth ride for the transported vehicles. Any issues with the suspension system can cause excessive bouncing, uneven tire wear, or poor handling.
Worn Out Shock Absorbers
Shock absorbers play a crucial role in the suspension system by dampening the vibrations and shocks. Over time, the shock absorbers can wear out, reducing their effectiveness. To check the shock absorbers, bounce the trailer up and down at each corner. If the trailer continues to bounce several times after you release it, the shock absorbers may be worn out. Replace any worn-out shock absorbers with new ones that are compatible with your trailer's suspension system.
Broken Springs
The springs in the suspension system help to support the weight of the trailer and the vehicles being transported. If a spring breaks, it can cause the trailer to sag on one side, leading to uneven tire wear and poor handling. Inspect the springs regularly for any signs of damage or breakage. If you find a broken spring, you'll need to replace it immediately. Make sure to choose a spring that is the same size and rating as the original.
Misaligned Axles
Misaligned axles can cause uneven tire wear, poor handling, and increased fuel consumption. To check for misaligned axles, measure the distance between the tires on each side of the trailer at the front and rear. If the distances are not equal, the axles may be misaligned. You'll need to have the axles realigned by a professional mechanic. A misaligned axle can cause significant damage to the trailer and the tires if not addressed promptly.
Tires and Wheels
The tires and wheels of a 6 car hauler trailer are subjected to a lot of stress and wear. Proper maintenance of the tires and wheels is essential for safe and efficient operation.
Tire Pressure
Check the tire pressure regularly using a tire pressure gauge. Underinflated tires can cause increased fuel consumption, poor handling, and premature tire wear. Overinflated tires can also be dangerous, as they are more prone to blowouts. Refer to the trailer's user manual or the tire manufacturer's recommendations for the correct tire pressure. Make sure to check the tire pressure when the tires are cold, as the pressure can increase when the tires are hot.
Tire Tread Wear
Inspect the tire tread regularly for signs of wear. The tire tread provides traction and helps to prevent hydroplaning. If the tire tread is worn down to the minimum legal limit, it's time to replace the tires. You can use a tread depth gauge to measure the tire tread. In most states, the minimum legal tread depth is 2/32 of an inch. If the tread depth is less than this, replace the tires immediately.
Wheel Alignment
Proper wheel alignment is important for even tire wear and optimal handling. If you notice that the trailer is pulling to one side or if the tires are wearing unevenly, the wheels may be out of alignment. Have the wheels aligned by a professional mechanic. A wheel alignment will ensure that the tires are rolling straight and evenly, reducing tire wear and improving fuel efficiency.
Other Common Problems
In addition to the above issues, there are a few other common problems that you may encounter with a 6 car hauler trailer.
Coupling Issues
The coupling is the connection between the trailer and the towing vehicle. Any issues with the coupling can cause the trailer to become detached while in transit, which is extremely dangerous. Regularly inspect the coupling for any signs of damage or wear. Make sure that the coupling is properly secured and locked before towing the trailer. Check the safety chains to ensure that they are attached securely and that they have enough slack to allow for turning and maneuvering.
Rust and Corrosion
Exposure to the elements can cause rust and corrosion to develop on the trailer. Rust and corrosion can weaken the structural integrity of the trailer and lead to premature failure of components. To prevent rust and corrosion, keep the trailer clean and dry. Apply a protective coating or paint to the trailer to prevent moisture from reaching the metal. If you notice any signs of rust or corrosion, treat it immediately using a rust converter or a rust-resistant paint.
Loading and Unloading Problems
Proper loading and unloading of the vehicles onto the trailer is crucial for the safety of the vehicles and the trailer. Make sure to distribute the weight evenly across the trailer to prevent overloading and to ensure proper handling. Use ramps or a lift gate to load and unload the vehicles safely. Secure the vehicles to the trailer using tie-down straps or chains to prevent them from shifting during transit.
Conclusion
Troubleshooting common problems with a 6 car hauler trailer requires a combination of regular maintenance, careful inspection, and timely repairs.
