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 signs of a worn or failing axle, and how can I troubleshoot axle issues?
Identifying the signs of a worn or failing axle is important for maintaining the safety and functionality of your vehicle. Here are some common signs to look out for and troubleshooting steps you can take to diagnose potential axle issues:
- Unusual Noises:
- Vibrations:
- Uneven Tire Wear:
- Difficulty Steering:
- Visible Damage or Leaks:
- Professional Inspection:
If you hear clunking, clicking, or grinding noises coming from the area around the wheels, it could indicate a problem with the axle. These noises may occur during acceleration, deceleration, or when turning. Troubleshoot by listening carefully to the location and timing of the noises to help pinpoint the affected axle.
A worn or failing axle can cause vibrations that can be felt through the steering wheel, floorboard, or seat. These vibrations may occur at certain speeds or during specific driving conditions. If you experience unusual vibrations, it’s important to investigate the cause, as it could be related to axle problems.
Inspect your tires for uneven wear patterns. Excessive wear on the inner or outer edges of the tires can be an indication of axle issues. Misaligned or damaged axles can cause the tires to tilt, leading to uneven tire wear. Regularly check your tires for signs of wear and take note of any abnormalities.
A worn or damaged axle can affect steering performance. If you experience difficulty in steering, such as stiffness, looseness, or a feeling of the vehicle pulling to one side, it may be due to axle problems. Pay attention to any changes in steering responsiveness and address them promptly.
Inspect the axles visually for any signs of damage or leaks. Look for cracks, bends, or visible fluid leaks around the axle boots or seals. Damaged or leaking axles can lead to lubrication loss and accelerated wear. If you notice any visible issues, it’s important to have them inspected and repaired by a qualified mechanic.
