SELECTING THE PROPER TRAILER AXLE
When selecting an axle for your application remember to consider the following important specifications:

  • LOAD CAPACITY:  the load rating of the axle must support the maximum gross vehicle weight rating. For multiple axle trailers divide the GVWR by the number of axles to determine the minimum load capacity of each axle.

  • TRACK LENGTH:  measure your axle track length by determining the distance between the center of 1 tire to the center of the other tire. A more precise measurement can be made by measuring the distance from 1 ‘HUB FACE’ to the other. The hub face is also known as the mounting surface where the wheel studs are located.

  • SPRING CENTERS:  measure the distance from the center of 1 spring to the center of the other.
    NOTE: not required for replacement torsion axles

  • OVERALL LENGTH:  measure the distance from the very end of an axle’s spindle to the very end of the opposite spindle.

  • AXLE STYLE:  important when reusing old mounting hardware and also for proper tire clearance. Includes straight axles (round or square), drop axles with offset spindles, and torsion axles. Also consider spindle size when reusing existing hubs or drums.

  • AXLE CAMBER:  Most trailer axles are designed with a bend in the tube that will deflect when the load (weight of the trailer) is applied. This will theoretically bring the trailer wheel camber toward a 0 value that is the best setting for most trailer applications. This will allow the tires to wear evenly and allow the longest tread life. Camber can be affected by damage to the axle. For example, if the axle spindle is bent, this will usually cause a negative camber on that side which will cause excess tread wear on the inside of that tire.

     

How can I tell between a torsion axle and leaf spring axle?

If you have spring axle suspension your trailer will have leaf springs. Your suspension should look similar to this:

If you have torsion axle suspension your trailer will look similar to this:

What are the pros and cons of a leaf sprung axles and torsion axles?
Both torsion and suspensions have a record of reliability. There are advantages and disadvantages to both, but it comes down to your preference because they both work great in their own way.
Torsion axles are made up of thick rubber cords concealed in the axle’s tubing. As each wheel moves up and down, the rubber cords compress offering an even wheel suspension for a smooth ride. Each wheel acts independently, moving and absorbing shocks.Torsion axles are mounted directly to the frame which means fewer moving parts compared to spring suspensions, resulting in a smoother shock action. This stiffens the frame, reducing flex.
This system is also less likely to corrode because the axle tube is galvanized inside and out. There are no metal-to-metal action like springs, so bare metal isn’t exposed, preventing corrosion. There are fewer working parts in a torsion suspension, therefore less maintenance is required.
The disadvantages of torsion are they are more expensive than spring suspensions and more expensive to repair or replace. There is also no impact distribution, so if you hit a curb, the full impact is on 1 wheel or set of wheels.

Leaf springs have been used for centuries and have proven to be solid performers. This is the most widely used suspension system due to its affordability. Spring suspensions are the most dependable for even tire wear and a steady ride, especially in multi-axle applications. Leaf springs better absorb the load from uneven ground or shock from a pothole. Each tire has its own set of springs. If you have to store your trailer on uneven ground, the independent wheel suspension means the trailer will hold up better over time. Spring suspensions are cheaper and easier to repair compared to torsion suspensions.One con of springs is the metal-on-metal design can lead to faster wear, leading to more frequent repairs. Spring suspensions also tend to be a bouncy ride with an empty load or on uneven, rough roads.

What are the key differences between live axles and dead axles in vehicle design?

In vehicle design, live axles and dead axles are two different types of axle configurations with distinct characteristics and functions. Here’s a detailed explanation of the key differences between live axles and dead axles:

Live Axles:

A live axle, also known as a solid axle or beam axle, is a type of axle where the wheels on both ends of the axle are connected and rotate together as a single unit. Here are the key features and characteristics of live axles:

  1. Connected Wheel Movement: In a live axle configuration, the wheels on both ends of the axle are linked together, meaning that any movement or forces applied to one wheel will directly affect the other wheel. This connection provides equal power distribution and torque to both wheels, making it suitable for off-road and heavy-duty applications where maximum traction is required.
  2. Simple Design: Live axles have a relatively simple design, consisting of a solid beam that connects the wheels. This simplicity makes them durable and capable of withstanding heavy loads and rough terrains.
  3. Weight and Cost: Live axles tend to be heavier and bulkier compared to other axle configurations, which can impact the overall weight and fuel efficiency of the vehicle. Additionally, the manufacturing and maintenance costs of live axles can be lower due to their simpler design.
  4. Suspension: In most cases, live axles are used in conjunction with leaf spring or coil spring suspensions. The axle is typically mounted to the vehicle’s chassis using leaf springs or control arms, allowing the axle to move vertically to absorb bumps and provide a smoother ride.
  5. Off-road Capability: Live axles are commonly used in off-road vehicles, trucks, and heavy-duty applications due to their robustness, durability, and ability to deliver power to both wheels simultaneously, enhancing traction and off-road performance.

Dead Axles:

A dead axle, also known as a dummy axle or non-driven axle, is a type of axle that does not transmit power to the wheels. It is primarily used to provide support and stability to the vehicle. Here are the key features and characteristics of dead axles:

  1. Independent Wheel Movement: In a dead axle configuration, each wheel operates independently, meaning that the movement or forces applied to one wheel will not affect the other wheel. Each wheel is responsible for its own power delivery and traction.
  2. Weight Distribution: Dead axles are often used to distribute the weight of the vehicle more evenly, especially in cases where heavy loads need to be carried. By adding an extra axle without driving capability, the weight can be distributed over a larger area, reducing the load on other axles and improving stability.
  3. Steering: Dead axles are commonly used as front axles in vehicles with rear-wheel drive configurations. They provide support for the front wheels and allow for steering control. The steering is typically achieved through a separate mechanism, such as a steering linkage or a steering gear.
  4. Reduced Complexity: Dead axles are simpler in design compared to live axles since they do not have the additional components required for power transmission. This simplicity can lead to lower manufacturing and maintenance costs.
  5. Efficiency and Maneuverability: Dead axles are often used in vehicles where power delivery to all wheels is not necessary, such as trailers, certain types of buses, and some light-duty vehicles. By eliminating the power transmission components, these vehicles can achieve better fuel efficiency and improved maneuverability.

It’s important to note that the choice between live axles and dead axles depends on the specific application, vehicle type, and desired performance characteristics. Vehicle manufacturers consider factors such as load capacity, traction requirements, off-road capability, cost, and fuel efficiency when determining the appropriate axle configuration for a particular vehicle model.

Are there specific maintenance tips to extend the lifespan of my vehicle’s axles?

Maintaining the axles of your vehicle is crucial for ensuring their longevity, performance, and overall safety. Here are some specific maintenance tips to extend the lifespan of your vehicle’s axles:

  1. Regular Inspection:
  2. Perform regular visual inspections of the axles to check for any signs of damage, leaks, or excessive wear. Look for cracks, bends, or rust on the axle housing, and inspect the axle shafts, seals, and boots. Early detection of issues can help prevent further damage and costly repairs.

  3. Lubrication:
  4. Follow the manufacturer’s recommendations for axle lubrication. Proper lubrication helps reduce friction and wear on the axle components. Regularly check the axle’s lubricant level and quality, and replace it as necessary. Use the recommended lubricant type and viscosity for your specific axle.

  5. Seal Inspection and Replacement:
  6. Check the axle seals for any signs of leaks, such as fluid accumulation around the axle ends. Leaking seals can allow contaminants to enter the axle assembly, leading to premature wear and damage. Replace worn or damaged seals promptly to maintain proper lubrication and prevent contamination.

  7. Proper Loading and Towing:
  8. Ensure that you do not exceed the weight capacity of your vehicle’s axles. Overloading or towing beyond the recommended limits can put excessive stress on the axles, leading to premature wear or failure. Be mindful of the payload and towing capacity specified by the vehicle manufacturer.

  9. Driving Techniques:
  10. Adopt proper driving techniques to minimize stress on the axles. Avoid sudden acceleration, aggressive cornering, and harsh braking, as these actions can subject the axles to excessive forces. Additionally, be cautious when driving over rough terrain or obstacles to prevent impacts that could damage the axles.

  11. Regular Wheel Alignment:
  12. Maintain proper wheel alignment to prevent excessive strain on the axles. Misaligned wheels can put uneven loads on the axles, leading to accelerated wear. Regularly check and adjust the wheel alignment as per the manufacturer’s recommendations.

  13. Proper Tire Inflation:
  14. Ensure that your vehicle’s tires are properly inflated according to the recommended tire pressure. Underinflated or overinflated tires can affect the load distribution on the axles and increase the risk of axle damage. Regularly check and maintain the correct tire pressure.

  15. Service Intervals:
  16. Follow the recommended service intervals for your vehicle, which may include axle inspections, lubricant changes, and other maintenance tasks. Adhering to these intervals ensures that the axles are properly maintained and any potential issues are addressed in a timely manner.

It’s important to consult your vehicle’s owner’s manual for specific maintenance guidelines and intervals provided by the manufacturer. Additionally, if you notice any unusual noises, vibrations, or handling issues related to the axles, it is advisable to have your vehicle inspected by a qualified mechanic to identify and address any potential axle problems promptly.

What are the factors to consider when choosing an axle for a custom-built vehicle?

Choosing the right axle for a custom-built vehicle is crucial for ensuring optimal performance, durability, and safety. Here are several key factors to consider when selecting an axle for a custom-built vehicle:

  1. Vehicle Type and Intended Use:
  2. Consider the type of vehicle you are building and its intended use. Factors such as vehicle weight, power output, terrain (on-road or off-road), towing capacity, and payload requirements will influence the axle selection. Off-road vehicles may require axles with higher strength and durability, while performance-oriented vehicles may benefit from axles that can handle increased power and torque.

  3. Axle Type:
  4. Choose the appropriate axle type based on your vehicle’s drivetrain configuration. Common axle types include solid axles (live axles) and independent axles. Solid axles are often used in heavy-duty applications and off-road vehicles due to their robustness and ability to handle high loads. Independent axles offer improved ride quality and handling characteristics but may have lower load-carrying capacities.

  5. Weight Capacity:
  6. Determine the required weight capacity of the axle based on the vehicle’s weight and intended payload. It’s crucial to select an axle that can handle the anticipated loads without exceeding its weight rating. Consider factors such as cargo, passengers, and accessories that may contribute to the overall weight.

  7. Axle Ratio:
  8. Choose an axle ratio that matches your vehicle’s powertrain and desired performance characteristics. The axle ratio affects the torque multiplication between the engine and wheels, influencing acceleration, towing capability, and fuel efficiency. Higher axle ratios provide more torque multiplication for improved low-end power but may sacrifice top-end speed.

  9. Braking System Compatibility:
  10. Ensure that the chosen axle is compatible with your vehicle’s braking system. Consider factors such as the axle’s mounting provisions for brake calipers, rotor size compatibility, and the need for an anti-lock braking system (ABS) if required.

  11. Suspension Compatibility:
  12. Consider the compatibility of the chosen axle with your vehicle’s suspension system. Factors such as axle mounting points, suspension geometry, and overall ride height should be taken into account. Ensure that the axle can be properly integrated with your chosen suspension components and that it provides sufficient ground clearance for your specific application.

  13. Aftermarket Support:
  14. Consider the availability of aftermarket support for the chosen axle. This includes access to replacement parts, upgrade options, and technical expertise. A robust aftermarket support network can be beneficial for future maintenance, repairs, and customization needs.

  15. Budget:
  16. Set a realistic budget for the axle selection, keeping in mind that high-performance or specialized axles may come at a higher cost. Balance your requirements with your budget to find the best axle option that meets your needs without exceeding your financial limitations.

When choosing an axle for a custom-built vehicle, it’s recommended to consult with knowledgeable professionals, experienced builders, or reputable axle manufacturers. They can provide valuable guidance, assist in understanding technical specifications, and help you select the most suitable axle for your specific custom vehicle project.
