A lightweight axle is a component in a vehicle's suspension system designed to reduce the overall weight of the vehicle while maintaining the necessary strength and durability to support the vehicle's weight and endure the forces encountered during operation. By reducing the mass of the axles, manufacturers can improve fuel efficiency, acceleration, and handling characteristics of the vehicle.
Light Duty Trailer Axles: Are They a Good Fit For You?
What can a light-duty axle haul?
Light-duty axle trailers are commonly used for hauling recreational equipment, such as bikes and kayaks, as well as low-weight equipment. If you are hauling heavier loads, a light-duty axle is not a good fit for you.
Is a light-duty axle the right axle for you?
Before deciding which type of trailer to buy or axle to install on your new trailer, first, you need to consider these important facts about light-duty axles.
Lower Price Point
A lower-weight rated axle means a lower price point. Even better, the lower price point of light-duty axles usually extends to the maintenance cost. They are cheaper to replace if you get in an accident. A light-duty axle is attractive to new haulers who may be investing in their very first trailer.
Smaller Haul Vehicle
The trailers supported by light-duty axles can usually be pulled by smaller SUVs, pickup trucks, and some crossovers.
Fewer Parts
Light-duty axles are easy to configure and use fewer parts, such as bolts. This means they are easier to install and easier to detect if there may be an issue.
Maneuverability
Light-duty axles also play a part in the maneuverability of your trailer. When you haven't hauled a trailer before, it takes time to get used to the extra weight attached to your vehicle. It also takes time to get used to the wider turns, further following distance, increased stopping time, and more. Smaller axles can help you easily transition into pulling a trailer as you adapt to the handling.
Best on Easy Terrain
Light-duty axles haul best on well-maintained roads. Because they can only handle lower weights, these types of axles are great in places with minimal snow, ice, or flooding. The wheels on a light-duty axle are smaller and won't handle gravel roads with bumps and hills as well as a medium or heavy-duty axle can.
Trailer axles are normally divided into two different types: Spring axles and torsion axles. While these two types of axles perform the same basic job, the way they go about suspending and cushioning the trailer load is completely different.
Spring Trailer Axles
This type of trailer axle will be immediately recognizable to nearly anybody who has been around motor vehicles for any length of time. Much like the name suggests, spring axles are constructed of stacked flat spring stock in proportion to the load.
But rather than having the spring over the axle (like on a pickup truck), trailers normally have the axle slung over the springs. This decreases the ride height of the trailer, which is important for many reasons. Load stability is greater on a lower trailer, and they're easier to load and unload as well.
Spring axles are by far the most popular option when it comes to trailer suspension systems. They're inexpensive and relatively easy to maintain. In fact, spring axles often ship with the curved spring plates pre-attached and ready to install. This helps reduce overall costs even more.
What can members do?
These parts are also an ideal choice for multi-axle trailers, because each tire has its own set of springs. If you have to store your trailer on uneven ground, this independent wheel suspension means the trailer will hold up better over the long run.
Benefits of the spring axle include:
It's possible to perform extensive maintenance. Unlike torsion axles (next section below), parts can be easily changed out.
Spring axles provide the most dependable tire wear, especially on multi-axle trailers.
They're inexpensive and fairly easy for the manufacturer to install.
Spring axles don't require re-welding to replace an entire axle.
Spring axles excel in applications like:
Utility trailers
Dump trailers
Basically any type of commercially available trailer, with a few special exceptions
Torsion Trailer Axles
Rather than relying on the traditional tensioned and sprung flat steel plates of the spring axle, torsion trailer axles take a different approach entirely.
No metal springs of any type are used; rather, a series of long rubber cords are situated inside a square tube with an inner core piece that the torsion arms are secured to. This type of axle can be difficult to understand just by reading about them. In this case, a (moving) picture really is worth a thousand words:
As you can see, the above video shows the cross section of a torsion axle. The outer square steel tubing is the part that's actually secured to the frame. The inner square piece is secured to the respective wheels via the torsion bars.
When the wheel moves up and down on bumpy or uneven ground, the inner bar compresses the rubber cords along the length of their bearing surface. The contact points are simply the corners and edges of the center support. Unbelievably simple!
Benefits of the torsion axle include:
Maintenance free design. Lube your wheel bearings and that's it!
No metal-on-metal contact points
Independent wheel suspension
Quieter during travel
Ride height can be easily changed via adjustable torsion bars.
Cross-bar construction is directly welded to the frame, and adds stiffness
Great corrosion resistance, as torsion axles are usually galvanized inside and out
Warranty typically lasts longer than leaf spring axles
Half-torsion axles are also available, which means they come in two parts that don't need to span the width of the trailer. These short units are perfect for specialized, custom applications.
Unfortunately, the attached design of torsion axles means that any major repairs are going to require the axle to be cut off. They really aren't designed to be totally overhauled. But, their simplified construction usually means that repairs are seldom, if ever, needed.
Torsion axles excel in applications like:
Boat trailer axles
Salt water spray environments
Windy environments
Unusually bumpy or rough roads
Conditions where a lower ride height is needed
High vibration applications (like wood chippers)
Which Trailer Axle is Best?
You might be asking "Which is better, torsion or spring axles?” That's a complicated question. Torsion trailer axles offer a smoother ride and less maintenance. Leaf springs are more durable, less expensive and far easier to replace parts on.
Selecting the proper axle is as simple as determining your application, and figuring out the loads you need to carry. Whichever you choose, you'll see the best results by properly loading your trailer with the aim of getting the most wear out of the system you pick.
How To Tell The Weight Rating of A Trailer Axle
Life's full of mysteries, but your trailer axle's weight rating shouldn't be one of them. Usually the question of weight capacity comes up when you need to replace your axle, but you may also just want to know what's on your trailer for your own peace of mind. Below, we'll show you some simple ways to identify your axle's weight capacity. Let's get started!
If you're lucky, your axle will still have its sticker with the weight rating included. (It might clearly say "capacity," but if not, the term to look for is "GAWR" (Gross Axle Weight Rating). If you know your trailer's axles came stock from the manufacturer, you may also be able to check the sticker or plate on your trailer for this information.
If you don't have a weight rating sticker but you see a serial number stamped onto your axle, you can call the manufacturer and have them verify the capacity for you.
These are the most reliable (and easiest) ways to determine your axle's weight rating, so we always recommend them above other methods. However, if for some reason you absolutely can't use your sticker or serial number stamp, there are other identifying features that provide an idea of the axle's weight capacity. Let's look at how to obtain these "clues" below.
For round axles, the tube diameter is a good indicator of the axle's capacity. For instance, an axle with a 2-3/8" diameter will have a 3,500-lb capacity.
(Note that this only works for round axles. If you have a square axle, the axle tube won't tell you much. In that case, you'll need to look at #3 and #4 below.)
The challenge here is that sometimes round axle dimensions do overlap. For instance, a 3" tube might belong to a 5,200-lb, 6,000-lb, or 7,000-lb axle (or in certain cases of 'upgraded tubes' by Grand Design, 3,500-lb). If the tube diameter points to different axle capacities, you've narrowed it down, but you can still gather more information to try and get closer.
Your wheel bolt pattern (or lug pattern) won't be the defining feature that will reveal your axle's weight capacity, but it can help narrow it down, especially in conjunction with the tube diameter.
For instance, if you have a 3" tube, you know your axle capacity falls somewhere in the 3,500-7,000-lb range. If you've also got 6 lugs, you know it's probably not a 7,000-lb axle, since most axles of that capacity have 8 lugs. So you're likely looking at either a 5,200 or 6,000-lb axle (or in the case of Grand Design's 'upgraded tubes' 3,500-lbs).
If your axle clues are still pointing in different directions, you can use your wheel bearings to make your selection in many cases, since certain bearings are very common to specific axle sizes. For instance, if your 3"-diameter axle has inner bearing 25580 and outer bearing 02475, you can deduce that you have a 7,000-lb axle.
Your bearing identification numbers should be stamped onto the bearings themselves, but if the numbers aren't legible, you'll need a digital caliper to take a precise measurement. (Learn more about identifying your bearings here.)
The above steps will help you narrow down your axle weight rating. However, if you're replacing an axle, weight capacity is only one part of choosing the correct replacement.
It's important that your new axle's dimensions are the same as your current axle's so that it fits properly under your trailer. Two crucial measurements are the hub face and spring center. If you're caught between two axle capacities (for instance, a 5,200 and 6,000-lb axle), these dimensions will also help you choose the correct replacement axle.
How To Choose The Right Trailer Axle For Your Application
Choosing the right trailer axle for your application is an important decision that can have a significant impact on the performance and safety of your trailer. The right axle will ensure that your trailer is able to handle the load it is intended to carry, and will also ensure that your trailer is able to perform as expected. Here are some tips to help you choose the right trailer axle for your application.
Consider the Braking System:
The braking system of your trailer is also an important factor to consider when choosing the right trailer axle. Different types of braking systems can provide different levels of performance and safety, so it is important to choose the right braking system for your application.
By following these tips, you can ensure that you choose the right trailer axle for your application. This will help ensure that your trailer is able to handle the load it is intended to carry, and will also ensure that your trailer is able to perform as expected.
Determine the Load Capacity
The first step in choosing the right trailer axle is to determine the load capacity of your trailer. This will help you determine the type of axle that is best suited for your application. You should also consider the weight of the trailer itself, as well as any additional items that may be loaded onto the trailer.
Consider the Axle Type
There are several types of trailer axles available, including single-axle, tandem-axle, and triple-axle. Each type of axle has its own advantages and disadvantages, so it is important to consider the type of axle that is best suited for your application.
Consider the Suspension System
The suspension system of your trailer is an important factor to consider when choosing the right trailer axle. Different types of suspension systems can provide different levels of performance and stability, so it is important to choose the right suspension system for your application.
Common Maintenance Tips for Trailer Axles
Check the wheel bearings regularly. Wheel bearings should be checked at least once a year, or more often if the trailer is used frequently. Check for any signs of wear or damage, such as excessive play in the bearings, or any signs of overheating.
Inspect the axle for any signs of damage. Look for any signs of rust, corrosion, or other damage that could affect the performance of the axle.
Grease the axle regularly. Greasing the axle regularly will help to keep it in good condition and reduce wear and tear.
Check the brakes regularly. Make sure the brakes are in good working order and that all the components are in good condition.
Check the tires regularly. Make sure the tires are properly inflated and that there is no visible damage to the tread or sidewalls.
Check the suspension system. Make sure the suspension system is in good condition and that all the components are in good working order.
Check the wheel alignment. Make sure the wheels are properly aligned and that the trailer is tracking straight.
Check the wheel nuts. Make sure the wheel nuts are properly tightened and that they are not loose or missing.
Check the hitch. Make sure the hitch is properly secured and that all the components are in good working order.
Check the lights. Make sure the lights are in good working order and that all the bulbs are functioning properly.
