How to Determine Weight Capacity of Trailer Axle
Question:
I know I have a 4 leaf spring on my utility trailer. Is there a way to find out which load capacity my axle is? I snapped the spring on my last trip. I have yet to remove it was trying to understand what I should be looking for before talking it apart. Thank you for any help.

To find the load capacity for your axle you should look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity.
You can also tell the weight capacity of the axle by measuring the diameter of the axle. Here is a list that will show the axle weight capacity based on the axle diameter:
Typical Axle Diameters Based on Axle Capacity:
- 1,000-lb - 2,000-lb Axles: 1-1/2 inch diameter - 1-3/4 inch diameter - 2-3/8 inch diameter
- 3,500-lb Axles: 2-3/8 inch diameter - 3 inch diameter
- 6,000-lb - 7,200-lb Axles: 3 inch diameter
- 8,000-lb Axles: 3-1/2 inch diameter
- 9,000-lb Axles: 4 inch diameter
- 10,000-lb Or more axles: 5 inch diameter
If you cannot determine the weight capacity using the above suggestions the next step would be to measure bolt pattern on the hub, size of brakes, and bearing part numbers, to narrow down the capacity of your axle.
The more information you can provide the better we can find you a solution.
