The Best Trailer Axle
Last updated on January 9th, 2019 at 06:35 pm
Irrespective of whether you have a small or a large sized trailer, if you are not careful with the Gross Axle Weight Rating (GAWR), then your trailer axle can be under a lot of unwanted stress due to the added weight.
The axle is assigned the crucial role of carrying the load and transmitting the power to the tires.
People often make the mistake of making fancy additions that increase the GVWR (Gross Vehicle Weight Rating) without upgrading the stock axles.
The result is that the axle gets damaged a lot sooner than it should. Some of the telltale signs of an axle gone bad are excessive vibration, change in the wheel alignment and a humming sound when you are cornering the vehicle. In extreme cases, the vehicle can put you in a deadlock right in the middle of a drive.
Not the best of situations to be stuck in.
If you have made excessive modifications to your trailer or are regularly exceeding the weight capacity, then an axle upgrade will save you from a lot of hassles and also a probable breakdown in the middle of nowhere.
However, an axle is not an inexpensive replacement. As a consumer, it is in your best interests to know what to look for when you are out to buy a replacement for your trailer. Unlike the days of yore, when a small junkyard trip would have given you a pretty good used axle, today the best place to search for one is the aftermarket.
Things to consider while buying a trailer axle
There are two different types of axles that you need to be aware when looking for a replacement.
Spring Axles: The leaf spring is the more common of the two and is usually the stock variety that is found on most complete trailer assemblies. It features flat and curved leaves that are layered one above the other and are usually installed below the axle itself. These are an inexpensive suspension system and can also be repaired if it gets damaged.
If your trailer features more than one axle, then a leaf spring assembly allows a more even weight distribution and provides a stable and steady ride. Each spring is independent of the other and this also allows better weight distribution when you are parking the trailer on uneven terrain.
However, these are slightly bulkier as compared to Torisons and will occupy more space in the assembly. Also, they are considered to be more durable and low on maintenance than Torison.
Torison Axle: Torison axles are a minimalistic but very popular option due to the easy construction and the adjustability. Further, it features four shock absorbent rubber cords inside the axle which also handles suspension. The compression of the rubber cords when each wheel moves allows for a smooth and hassle-free ride.
The pros of a torsion axle are that these are galvanized from both sides and there is little to no contact between metal parts resulting in less corrosion. Also, since the axle is attached to the trailer frame, it gives the trailer a rigidity.
However, the flipside is that if you have a damaged Torrison axle, then you cannot repair it. Replacing the entire suspension system is the only option due to the attached construction. Torrisons also perform poorly in snow or extremely low temperatures due to the rubber cords getting frozen and losing the elasticity.
If you are confused in your quest to seek a quality replacement for your trailer axle, then here’s a small list of the best trailer axle assemblies in the market currently. We have picked these on the basis of the quality, the price and the ease of assembly. Systems that bolt-on as a direct replacement for your existing trailer axle has been rated slightly higher.
