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 do solid axles differ from independent axles in terms of performance?
When comparing solid axles and independent axles in terms of performance, there are several key differences to consider. Both types of axles have their advantages and disadvantages, and their suitability depends on the specific application and desired performance characteristics. Here’s a comparison of solid axles and independent axles:
| Aspect | Solid Axles | Independent Axles |
|---|---|---|
| Load-Bearing Capability | Solid axles have high load-bearing capability due to their robust and sturdy construction. They can handle heavy loads and provide excellent stability, making them suitable for off-road vehicles, heavy-duty trucks, and towing applications. | Independent axles typically have lower load-bearing capability compared to solid axles. They are designed for lighter loads and offer improved ride comfort and handling characteristics. They are commonly used in passenger cars, sports cars, and vehicles with a focus on maneuverability and road performance. |
| Wheel Articulation | Solid axles have limited wheel articulation due to their connected and rigid design. This can result in reduced traction and compromised wheel contact with the ground on uneven terrain. However, solid axles provide excellent traction in situations where the weight distribution on all wheels needs to be maintained, such as in off-road or rock-crawling applications. | Independent axles offer greater wheel articulation as each wheel can move independently of the others. This allows the wheels to better conform to uneven terrain, maximizing traction and maintaining contact with the ground. Independent axles provide improved off-road capability, enhanced handling, and better ride comfort. |
| Ride Comfort | Due to their rigid design, solid axles generally provide a stiffer and less compliant ride compared to independent axles. They transmit more road shocks and vibrations to the vehicle’s occupants, resulting in a rougher ride quality. | Independent axles are known for providing better ride comfort. Each wheel can react independently to road imperfections, absorbing shocks and vibrations more effectively. This leads to a smoother and more comfortable ride, particularly on paved roads and surfaces with minor irregularities. |
| Handling and Stability | Solid axles offer excellent stability due to their connected nature. They provide better resistance to lateral forces, making them suitable for high-speed stability and towing applications. However, the rigid axle design can limit overall handling and maneuverability, particularly in tight corners or during quick direction changes. | Independent axles generally offer improved handling and maneuverability. Each wheel can react independently to steering inputs, allowing for better cornering performance and agility. Independent axles are commonly found in vehicles where precise handling and responsive steering are desired, such as sports cars and performance-oriented vehicles. |
| Maintenance and Repair | Solid axles are relatively simpler in design and have fewer moving parts, making them easier to maintain and repair. They are often more resistant to damage and require less frequent servicing. However, if a component within the axle assembly fails, the entire axle may need to be replaced. | Independent axles are typically more complex in design and have multiple moving parts, such as control arms, CV joints, or bearings. This complexity can result in higher maintenance and repair costs. However, if a failure occurs, only the affected component needs to be replaced, reducing repair expenses compared to replacing the entire axle. |
It’s important to note that advancements in suspension and axle technologies have resulted in various hybrid systems that combine features of solid and independent axles. These systems aim to provide a balance between load-bearing capability, wheel articulation, ride comfort, and handling performance based on specific application requirements.
In summary, solid axles excel in load-bearing capability, stability, and durability, making them suitable for heavy-duty applications and off-road conditions. Independent axles offer improved ride comfort, better wheel articulation, enhanced handling, and maneuverability, making them suitable for passenger cars and vehicles focused on road performance.
