Measuring a Trailer Axle




How To Order An Axle

1.Select your axle based on the current style you currently have on your trailer. You want an axle that is similar to the one currently under the trailer to avoid any problems with clearance. Be sure to identify axle over or axle under springs when you select your part number

2.We need your axle track measurement. This measurement is taken from the face of one hub to the face of the other hub where the rim touches the hub. DO NOT measure from the back of the hub or brake flange as this will provide an incorrect track measurement. MEASURE HUB FACE TO HUB FACE ONLY

3.The only other measurement needed is the spring center. This measurement is from the center of one spring to the center of the opposite spring. This is a very important measurement as this is where your springs will sit on the axle.

(Quick Tip)

An easy way to measure your spring center is to hook a tape on the outside of one spring and measure to the inside of the opposite spring. This will give you an accurate measurement.

End to End Spindle Measurement

To do this one, you have to pull the wheels off of both sides. Now hook your tape measure on the outside of one spindle and extend to the same point on the opposite side. Please let the sales person taking your order or when you place the order online that you are providing a TIP TO TIP measurement so that Champion Trailer can build your trailer axle correctly.

What if your axle is broken.

If your axle is broken outside of the spring, there is still hope. You can still get the hub face measurement provided:

  1. You are still able to take a spring center measurement.
  2. One of the sides of the axle is intact.

If that is the case, take the spring measurement as above.

Then, on the good side, measure from the spring center to the outside hub face. Multiply that measurement times two and add it to the spring center measurement to obtain your hub face length.

If you don't happen to have the hub on the good side of the broken axle but the good side is otherwise unharmed, you can still get the measurement.

Again, we assume that the axle is not broken between the springs. Get the spring center measurement as above. Now, on the good side, measure from the center of the spring to the tip of the spindle and multiply that by two and add to the spring center measurement.
