How Do I Measure Hitch Ball Size For Uhaul Trailer?

Measuring the hitch ball size for a Uhaul trailer is a relatively simple process:
Determine the Coupler Size
First, you will need to determine the coupler size of your Uhaul trailer.
This can typically be found on the side of the trailer itself or in your owner’s manual.
Measure the Diameter
Once you have determined this measurement, you will need to measure the diameter of the ball hole which is located at the front end of the trailer where it attaches to the tow vehicle.
The diameter measurement should match exactly with that of the coupler size determined previously.
Check the Capacity
Next, you will need to check your weight capacity and make sure that it exceeds that of your gross weight.
To do this, you can look up your Uhaul model online and find its corresponding weight capacity.
Determine Hitch Size Ball
Once you have these two measurements, you can use them to determine what size hitch ball will fit best for your Uhaul trailer needs.
Most hitch balls come with a designated shank size which should also match that of your coupler size and ball hole diameter measurements taken earlier.
It’s important to make sure that all three measurements are met so as not to cause any issues when trying to tow with a Uhaul trailer which could potentially result in an unsafe or dangerous situation.
Note
Additionally, it is important to note that there are two types of hitch balls available: standard hitch balls and adjustable hitch balls.
Standard hitch balls come in pre-marked sizes with corresponding weights capacities while adjustable ones come with adjustable sizes and weights capacities allowing for more flexibility when selecting a fitting ball for a particular application or conditions.
