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.

What is the primary function of an axle hub in a vehicle’s wheel assembly?
The primary function of an axle hub in a vehicle’s wheel assembly is to connect the wheel to the axle and provide a mounting point for the wheel bearings. Here’s a detailed explanation of the primary functions of an axle hub:
1. Wheel Mounting:
The axle hub serves as the component that connects the wheel to the vehicle’s axle. It is typically a cylindrical or disc-shaped structure located at the center of the wheel assembly. The hub contains bolt holes or studs that align with the corresponding holes or studs on the wheel, allowing for secure attachment and proper alignment of the wheel.
2. Bearing Support:
The axle hub provides a mounting point for the wheel bearings. Wheel bearings are crucial components that allow the wheel to rotate smoothly while supporting the weight of the vehicle. The hub contains a bearing race or races, which are machined surfaces that support the inner and outer wheel bearings. The bearings fit snugly into the hub and enable the wheel to rotate freely around the axle.
3. Load Transmission:
Another important function of the axle hub is to transmit the load from the wheel to the axle. As the vehicle moves, various forces act on the wheel, including the weight of the vehicle, acceleration and braking forces, and lateral forces during turns. The axle hub, along with the wheel bearings, helps distribute and transfer these forces from the wheel to the axle, allowing for smooth and controlled movement of the vehicle.
4. Hub Assembly Integration:
In many vehicles, the axle hub integrates with other components of the wheel assembly. For example, it may have provisions for attaching the brake rotor or drum, which are essential for the vehicle’s braking system. In vehicles with front-wheel drive or all-wheel drive, the axle hub may also incorporate features for connecting the CV (constant velocity) joint or driveshaft, allowing for power transmission to the wheels.
5. Wheel Alignment:
The axle hub plays a role in maintaining proper wheel alignment. The hub’s design and dimensions are critical in ensuring that the wheel is centered and aligned correctly with the vehicle’s suspension system. Proper wheel alignment is essential for optimal handling, tire wear, and overall vehicle performance.
In summary, the primary function of an axle hub in a vehicle’s wheel assembly is to connect the wheel to the axle and provide a mounting point for the wheel bearings. It facilitates the secure attachment of the wheel, supports the wheel bearings for smooth rotation, transmits loads from the wheel to the axle, integrates with other components of the wheel assembly, and contributes to proper wheel alignment. The axle hub is a critical component that enables safe and efficient operation of the vehicle’s wheels.
Can a worn or damaged wheel bearing impact the performance of an axle hub?
Yes, a worn or damaged wheel bearing can significantly impact the performance of an axle hub. The wheel bearing plays a crucial role in supporting the weight of the vehicle and allowing the wheels to rotate smoothly. Here’s a detailed explanation of how a worn or damaged wheel bearing can affect the performance of an axle hub:
- Wheel rotation: The axle hub, along with the wheel bearing, enables the smooth rotation of the wheel. When the wheel bearing is worn or damaged, it can cause irregular or uneven rotation of the wheel. This can result in vibrations, noise, and an overall rough ride quality.
- Excessive play: A worn wheel bearing may develop excessive play or looseness. This can cause the wheel to wobble or have noticeable movement when jacked up or when driving. Excessive play in the wheel bearing can affect the vehicle’s stability, handling, and control, making it more difficult to steer accurately.
- Noise: Worn or damaged wheel bearings often produce noticeable noise. The noise can vary from a low humming or rumbling sound to a high-pitched whining or grinding noise. The noise may become more pronounced when turning or when the vehicle is under load. Ignoring the noise and continuing to drive with a faulty wheel bearing can lead to further damage and potential safety hazards.
- Heat buildup: A damaged wheel bearing may generate excessive heat due to increased friction and inadequate lubrication. The heat buildup can cause the bearing to expand, leading to further damage and potential failure. Overheated wheel bearings can contribute to premature wear of other components within the axle hub assembly, such as the axle shaft or hub assembly itself.
- Uneven tire wear: A worn or damaged wheel bearing can result in uneven tire wear. As the wheel doesn’t rotate properly or experiences excessive play, it can cause the tire to wear unevenly. This can lead to premature tire wear on specific areas of the tread, affecting the tire’s performance, lifespan, and overall safety.
- Reduced fuel efficiency: When a wheel bearing is damaged or worn, it can create additional resistance and drag on the wheel. This increased rolling resistance can have a negative impact on fuel efficiency, causing the vehicle to consume more fuel to maintain speed and overcome the additional resistance. Thus, a faulty wheel bearing can lead to decreased fuel efficiency and increased operating costs.
It’s important to address any signs of a worn or damaged wheel bearing promptly. If you suspect a problem with the wheel bearing or experience any of the symptoms mentioned above, it is recommended to have the vehicle inspected by a qualified mechanic or automotive technician. They can assess the condition of the wheel bearing and perform the necessary repairs or replacement to restore the proper performance of the axle hub and ensure safe operation of the vehicle.
In summary, a worn or damaged wheel bearing can have a significant impact on the performance of an axle hub. It can affect wheel rotation, cause excessive play, produce noise, lead to heat buildup, result in uneven tire wear, and reduce fuel efficiency. Prompt inspection and necessary repairs or replacement of a faulty wheel bearing are essential to maintain the optimal performance and safety of the axle hub.
How do changes in wheel offset affect the angles and performance of axle hubs?
Changes in wheel offset can have a significant impact on the angles and performance of axle hubs. Here’s a detailed explanation:
Wheel offset refers to the distance between the centerline of the wheel and the mounting surface. It determines how far the wheel and tire assembly will be positioned in relation to the axle hub. There are three types of wheel offsets: positive offset, zero offset, and negative offset.
Here’s how changes in wheel offset can affect the angles and performance of axle hubs:
- Camber Angle: Camber angle refers to the inward or outward tilt of the wheel when viewed from the front of the vehicle. Changes in wheel offset can impact the camber angle. Increasing positive offset or reducing negative offset typically results in more positive camber, while increasing negative offset or reducing positive offset leads to more negative camber. Improper camber angle can cause uneven tire wear, reduced traction, and handling issues.
- Track Width: Wheel offset affects the track width, which is the distance between the centerlines of the left and right wheels. Wider track width can improve stability and cornering performance. Increasing positive offset or reducing negative offset generally widens the track width, while increasing negative offset or reducing positive offset narrows it.
- Steering Geometry: Changes in wheel offset also impact the steering geometry of the vehicle. Altering the offset can affect the scrub radius, which is the distance between the tire contact patch and the steering axis. Changes in scrub radius can influence steering effort, feedback, and stability. It’s important to maintain the appropriate scrub radius for optimal handling and performance.
- Wheel Bearing Load: Wheel offset affects the load applied to the wheel bearings. Increasing positive offset or reducing negative offset generally increases the load on the inner wheel bearing, while increasing negative offset or reducing positive offset increases the load on the outer wheel bearing. Proper wheel bearing load is crucial for their longevity and performance.
- Clearance and Interference: Changes in wheel offset can also impact the clearance between the wheel and suspension components or bodywork. Insufficient clearance due to excessive positive offset or inadequate clearance due to excessive negative offset can lead to rubbing, interference, or potential damage to the axle hub, suspension parts, or bodywork.
It’s important to note that any changes in wheel offset should be done within the manufacturer’s recommended specifications or in consultation with knowledgeable professionals. Deviating from the recommended wheel offset can lead to adverse effects on the axle hub angles and performance, as well as other aspects of the vehicle’s handling and safety.
When modifying wheel offset, it is crucial to consider the overall impact on the vehicle’s suspension geometry, clearance, and alignment. It may be necessary to make corresponding adjustments to maintain proper alignment angles, such as camber, toe, and caster, to ensure optimal tire wear, handling, and performance.
In summary, changes in wheel offset can have a significant impact on the angles and performance of axle hubs. They can affect camber angles, track width, steering geometry, wheel bearing load, and clearance. It is important to adhere to manufacturer’s specifications and consult with knowledgeable professionals when considering changes in wheel offset to ensure proper alignment, optimal performance, and safe operation of the vehicle.
