The spindle features a Stainless Steel Wear Sleeve to allow for long term protection for your seal surface. This ensures your seal surface won’t corrode away, meaning it will not pit or rust which would normally lead to letting water into your hub. Dexter Axle spindles also feature an E-Z Lube system, which allows easy greasing and regular maintenance of bearings. The grease travels through the center of the spindle and pushes out the old grease forward towards the front of the hub and out your dust cap, therefore replacing the old grease with new fresh grease. A castle nut and spindle washer are included on each spindle. These Hot-Dipped Galvanized Adjustable Spring Seats mean your axle will last longer, with no holes for saltwater and corrosion to hide. These Galvanized Adjustable Spring seats are included free of charge with the purchase of your axle.

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 trailer axles contribute to a trailer’s maneuverability and control?

Trailer axles play a crucial role in a trailer’s maneuverability and control. Here’s how they contribute:

  • Weight Distribution: The placement of trailer axles and the distribution of weight on them impact how a trailer handles. Proper weight distribution ensures stability and control during towing.
  • Balance: Balanced axles help prevent issues like swaying or fishtailing. The even distribution of weight across the axles promotes smoother and more controlled towing.
  • Number of Axles: Trailers with multiple axles generally have better weight distribution and stability. Tandem or multi-axle configurations help distribute the load evenly and enhance control.
  • Steering Geometry: Axle placement influences a trailer’s turning radius and maneuverability. Axles placed closer to the front or back can affect how sharply a trailer can turn.
  • Suspension Type: The type of suspension, whether leaf spring, torsion, or air suspension, can impact how well a trailer handles bumps and road imperfections, contributing to control and a smoother ride.
  • Braking Systems: Axles equipped with brakes provide additional control by assisting in slowing down or stopping the trailer. Electric, hydraulic, or surge brakes are common options.
  • Shock Absorption: Some axles come with shock absorbers to dampen vibrations and jolts, improving control by reducing the impact of road irregularities.
  • Tire Size and Quality: Properly sized and high-quality tires on trailer axles ensure good traction and control. Trailer tires with a higher load capacity can handle the weight more effectively.
  • Alignment and Maintenance: Regular maintenance, including keeping axles properly aligned and well-lubricated, is crucial for ensuring that the trailer’s axles operate optimally and contribute to control and stability.

In summary, the design, configuration, and maintenance of trailer axles significantly affect a trailer’s maneuverability and control. Properly chosen and maintained axles contribute to safe and predictable towing experiences.

What are the key considerations when selecting the right trailer axle for a specific application?

Choosing the appropriate trailer axle for a specific application involves several critical considerations:

  1. Weight Capacity: Determine the maximum weight the axle will need to support. This includes the trailer’s payload and the weight of the trailer itself. Ensure the selected axle has a weight capacity that exceeds the application’s requirements to provide a safety margin.
  2. Axle Type: Select the axle type based on the application. Common types include straight axles, drop axles, and torsion axles. The choice depends on factors like ground clearance, load height, and suspension design.
  3. Axle Configuration: Decide on the number of axles needed. Single axles are suitable for lighter loads, while tandem and tri-axle configurations offer higher weight capacities. Multi-axle setups provide better weight distribution.
  4. Suspension Type: Choose the appropriate suspension system, such as leaf spring, air ride, or torsion suspension. The suspension affects ride quality, load stability, and maintenance requirements.
  5. Brake System: Consider the braking requirements. Larger and heavier trailers often require electric or hydraulic brakes. Ensure the axle accommodates the necessary brake system, including the brake size and type.
  6. Axle Material: Select the axle material, typically steel or aluminum. Steel axles are durable and cost-effective, while aluminum axles are lighter and corrosion-resistant. The choice depends on the application’s demands and budget.
  7. Hub and Spindle Type: Choose hubs and spindles compatible with the axle. The hub style affects the type of wheel and tire you can use, while spindle size impacts weight capacity and bearing compatibility.
  8. Wheel Bolt Pattern: Ensure the axle’s hub and wheel bolt patterns match to avoid compatibility issues with the wheels and tires you plan to use.
  9. Ground Clearance: Consider the required ground clearance for the application. Lower ground clearance may be suitable for highway travel, while off-road or specialty trailers may need increased clearance.
  10. Legal Compliance: Ensure that the selected axle and trailer configuration comply with local and national regulations regarding weight limits, axle spacing, and safety requirements.
  11. Manufacturer and Warranty: Choose a reputable axle manufacturer with a track record for quality and durability. Check the warranty and support offered by the manufacturer.
  12. Budget: Evaluate the budget constraints for the axle and select an option that balances cost-effectiveness with meeting the application’s needs.

By carefully considering these factors, you can select the right trailer axle that ensures safe and efficient performance for your specific application.

How does the placement of trailer axles affect weight distribution and towing?

The placement of trailer axles plays a crucial role in weight distribution and towing characteristics. There are two primary axle configurations: single axle and tandem axle, each with distinct effects:

1. Single Axle Trailers:

– Single axle trailers have only one axle positioned toward the rear of the trailer. This configuration is common in smaller utility and light-duty trailers.

– Weight Distribution: With a single axle, more of the trailer’s weight is concentrated toward the rear. This can lead to inadequate weight distribution and make the trailer prone to swaying or fishtailing during towing.

– Towing Characteristics: Single axle trailers are generally easier to maneuver and tow, making them suitable for smaller loads and shorter trips. However, they may lack stability with heavier loads.

2. Tandem Axle Trailers:

– Tandem axle trailers feature two axles placed closer together, typically with one in front of the other. This design is commonly found in larger trailers and offers several advantages.

– Weight Distribution: Tandem axles distribute the trailer’s weight more evenly. This improves stability and reduces the risk of swaying. The weight is better balanced between the axles, leading to improved control during towing.

– Towing Characteristics: Tandem axle trailers are more stable and capable of handling heavier loads. They are less prone to sway, making them suitable for long-distance hauling and larger cargo.

– Additional Features: Tandem axle trailers may have braking systems, which further enhance safety and control during towing, especially when towing heavier loads.

– Considerations: It’s important to note that the placement of axles within a trailer also affects the tongue weight (the downward force on the hitch). Proper tongue weight is essential for safe towing, and it can be adjusted by positioning the cargo within the trailer.

– Ultimately, the choice between single and tandem axles depends on the trailer’s intended use and the weight of the cargo. Tandem axle trailers are preferred for heavier loads and long-distance towing, while single axle trailers are suitable for smaller, lighter loads and shorter trips. Proper weight distribution and adherence to safety guidelines are critical for safe and stable towing.
