What You Need to Know When Ordering Your New Trailer Axle

How To Measure your Hub Face for Your Trailer Axle

The hub face measurement (also known as the axle track) is one of the most important measurements you’ll need to find when replacing your axle.

The hub face (where your axle contacts the wheel and tire) is measured from the outer edge of one hub face to the outer edge of the opposite hub face.

Missing your axle hub? Try measuring brake-flange-to-brake-flange instead.

 This method isn’t quite as accurate as the hub face measurement, but if your axle’s hubs are missing, you can use what’s called a brake flange measurement instead. Measure from the outside face of one brake flange to the outside face of the opposite brake flange.Most axles have a standard amount of space between the brake flanges and hubs, depending on the axle size. If you know what capacity your axle is and you know your brake flange measurement, just add the standard flange-to-hub dimension to your brake flange length to obtain your hub face measurement. So what’s the standard distance between brake flanges and hubs? it depends on the axle’s weight capacity. For instance, 3,500-lb axles generally have 3″ between each flange and hub. So if we add 6″ (3″ for each side) to our brake flange measurement, we get our hub face number. (See our chart below for the correct number of inches to add to your brake flange measurement.)

How To Find Your Spring Center Measurement

The spring center measurement might be the most important to get right. You want to make sure your new axle’s springs are located in the same place as the old ones so they don’t obstruct the wheels, tires, or other components on your trailer. While holding your tape measure in the center of your spring, measure to the center of the opposite spring. (You’ll use the same method regardless of whether your trailer’s springs are mounted above or below the axle.)

Tip: If you don’t have a friend nearby to hold the end of the tape measure, you can still get this measurement solo. By hooking your tape measure on the outside edge of one spring, you can then measure to the inside edge of the other spring. This measurement will be identical to a center-to-center measurement.

Other Identifying Axle Features

Axle Capacity / Tube Diameter

Choose a new axle with the same capacity as your current axle. You can usually find your capacity on a sticker or stamp on the axle (or sometimes on the trailer itself, if your axles came OEM). If you can’t find your capacity this way, you can narrow it down by measuring the tube diameter.

A Wheel Bolt/Lug Pattern

Your trailer’s wheel bolt pattern is another feature you can use to find the axle you need. Specific bolt patterns are commonly seen on specific axle sizes

How to Measure a Broken Trailer Axle

If your trailer has Multiple Axles

If your trailer axle has been through it and is bent or damaged in some way, you may not be able to use the traditional measurements. In this case, here are a few other options.

If your trailer has a Single Axle

If you’ve only got one axle to work with, you might still be able to find your hub face measurement, even if your axle doesn’t have brake flanges. If your axle has brake flanges, use the brake flange to brake flange measurement we discussed above. 

If your axle doesn’t have brake flanges, and one of your hubs is missing or your axle is broken from the outer edge of the leaf spring, you can use the method below to find your measurement. (You cannot use this method if your axle has broken anywhere between the two leaf springs.

This will prevent you from measuring accurately, leading to an incorrect hub face measurement.)

  • Measure the distance from the center of one leaf spring to the outside edge of the hub face(measurement A)
  • Double the value 
  • Add the value to your spring center measurement

How To Measure your Bolt Pattern

For Hubs and Drums with Even Number of Bolts

To measure between the holes on a wheel with an even number of holes, simply measure from the center of one bolt hole to the center of its opposite to determine the diameter of the lug pattern.

For Hubs and Drums with Odd Number of Bolts

Measuring the diameter of a bolt circle with an odd number of lugs isn’t as straightforward.

You can’t measure straight across because there is no opposite bolt hole.

However, there are a few ways to get around this and figure out the bolt pattern you need for your new wheel.

Option 1

Measure from Center to Edge

An easy way to determine bolt hole circle diameter on wheels with 5 bolt holes is to measure from the center of one bolt hole to the farthest edge of one of the two farthest holes.

Option 2

Measure to Imaginary Bolt Hole Center

Measure from the center of one bolt hole to a point on the rim where the bolt hole would be on an odd-lug wheel. You must guess where this point is located if you want to measure the diameter this way.

Option 3

Measure Adjacent Holes

You can also measure the center-to-center distance of adjacent holes. Then, compare the distance to those in the list below to find the circle diameter.

Distance:

2-5/8″ – The bolt pattern is 5 on 4-1/2
2-3/4″ – The bolt pattern is 5 on 4-3/4
3″ – The bolt pattern is 5 on 5
3-1/4″ – The bolt pattern is 5 on 5-1/2
