By Position
Front axle: Also known as a steering axle, the front axle is found at the front of the trailer. Its main job is to support the front part of the trailer and provide a place for steering. It connects the wheels on the front of the trailer. A more accessible front axle is essential for trailers that need to be moved in tight areas.
Rear axle: As the name suggests, a rear axle is found at the back of the trailer. It connects the wheels at the back of the trailer and supports the trailer's weight. It provides stability and strength for the trailer, especially when hauling heavy loads. Some trailers may use double or tandem rear axles to increase their carrying capacity.
Center axle: The middle axle is placed beneath the trailer's center. This positioning helps to balance the trailer's weight and improves stability. For example, a center axle can be found on travel trailers to ensure they roll smoothly and are easy to tow. In addition, the middle axle can be used on utility trailers, especially when hauling large equipment.
By Design
Live axle: A live axle is a powered axle. It receives power from the engine through the drivetrain. Live axles are common in front-wheel-drive and all-wheel-drive vehicles. They provide traction and control, especially on slippery or uneven surfaces. For example, a live axle can be found on off-road trailers that need to be towed on rough terrain.
Dead axle: A dead axle is a non-powered axle. It does not receive power from the engine. Instead, it serves as a support point for the wheels. Dead axles are common in trailers and towed vehicles. For example, a dead axle can be found on camping trailers that are towed behind trucks or SUVs. Since the camping trailer does not need to steer itself, a dead axle is sufficient.
When it comes to trailer axle specifications, different types of trailer axles have distinct features that make them suitable for different kinds of trailers. Here are a few examples.
Materials
The material used to make the axle can affect its strength and its ability to bear weight. Axles are mostly made of steel or iron. Steel is a strong material that is used in heavy-duty axles. It is more durable than iron.
Axle Size
The size of the axle is determined by the diameter of the tube. Different trailer sizes have different axle sizes. Large trailers that carry heavy loads require axles with large diameters.
Weight Capacity
Different axles have varying weight capacities. The weight capacity of the axle is determined by its size and the material used to make it. Heavy-duty axles can support up to 10,000 pounds.
Brake Size
Trailer axles also have different brake sizes. The size of the brake is determined by the diameter of the brake drum. Axles with large drum sizes have larger brakes. They provide more stopping power and are suitable for heavy trailers.
Suspension System
The type of suspension system determines how easy the trailer is to handle. Axles with leaf spring suspensions are the most common. They are more affordable and require low maintenance. However, they do not provide much comfort. For luxury trailers, the axle may come with a torsion or air suspension system.
Maintaining trailer axles is an important part of trailer maintenance. This is because the condition of the axle affects the functionality and safety of the trailer. Here are some trailer axle maintenance tips.
Regular Inspection
Trailer owners should conduct regular inspections to assess the condition of the axle. They should look out for signs of wear, rust, or damage. It is also important to check the wheel bearings and brake components.
Lubrication
The trailer axle parts that require lubrication should be lubricated using the appropriate lubricant. This helps to reduce friction and prevents wear and tear. Trailer owners should also follow the manufacturer's lubrication schedule.
Load Management
Trailer owners should ensure that the load being carried does not exceed the weight capacity of the axle. Carrying excess load can put a strain on the axle and can lead to damage over time.
Brake Maintenance
Trailer owners should ensure that the brakes mounted on the axle are in good condition. They should check the brake pads regularly and replace them when they are worn out. It is also necessary to adjust the brakes to ensure they function properly.
Tire Maintenance
The condition of the tires can also affect the trailer axle. Trailer owners should check the tires regularly for signs of wear. They should ensure the tire pressure is at the recommended level.
Weight capacity:
It's important to choose an axle with the right weight capacity when loading trailers. The GVWR should be divided by the number of axles on the trailer. This number should be lower than the axle rating. This ensures the axle can handle the weight without damaging it.
Trailer type and use:
The type and use of the trailer are also important in choosing the right axle. For example, a travel trailer used for vacation will not need a heavy axle like a cargo trailer used for hauling goods. The axle should be chosen based on the trailer type and its use.
Axle configuration:
Axle configuration is another important factor to consider when choosing a trailer axle. Trailer axles come with different configurations such as tandem, single and triple. A tandem axle is the most common configuration. It provides more stability and weight distribution.
Braking system:
When choosing an axle for a trailer, the braking system is also an important factor to consider. Trailer axles come with different braking systems such as electric brakes, hydraulic brakes and surge brakes. Electric brakes are the most common type of braking system. They provide more stopping power and are easy to maintain.
Wheel size:
When choosing an axle for a trailer, wheel size is also an important factor to consider. Trailer axles come with different wheel sizes such as 13 inches, 14 inches and 15 inches. 14-inch wheel sizes are the most common. They provide a good balance between performance and durability.
Suspension system:
The suspension system is also an important factor to consider when choosing an axle for a trailer. Trailer axles come with different suspension systems such as leaf spring, coil spring and torsion axle. Leaf spring is the most common type of suspension system. It is durable and requires little maintenance.
Trailer axle replacement is a step-by-step process. First, gather the necessary tools and materials. These include safety gear, jacks, jack stands, lug wrench, socket set, wheel chocks, new trailer axle assembly, and mounting hardware.
Begin by ensuring safety. Park the trailer on a level surface and engage the parking brake. Wheel chocks are placed on the wheels that won’t be removed, and the trailer is raised with the jack. After this, the trailer should be supported with jack stands for stability.
The next step is to remove the wheels. The lug nuts are loosened with a lug wrench, and the wheels are removed. Depending on the type of axle, additional components such as brake drums or rotor may need to be removed. Follow the manufacturer’s instructions to remove these components safely.
Now, find the axle mounting hardware and remove it. This hardware varies depending on the axle type and trailer design. Common mounting methods include U-bolts and flange bolts. Once the mounting hardware is removed, disconnect any additional components like trailer suspension for axle support.
With the axle disconnected from the trailer, lift the old axle and lower the new one on the trailer. The new axle is aligned with the mounting points on the trailer. Ensure proper alignment to avoid handling and stability issues. Secure the new axle using the mounting hardware. Tighten all bolts and nuts securely.
Reinstall any removed components, such as brake drums and wheels. Now, lower the trailer by removing the jack stands and adjusting the jack. Before hitting the road, ensure the trailer tires are properly inflated. Check the axle's alignment and make any necessary adjustments.
