Introduction:

Trailer axles are an essential component of any towable vehicle, providing support and ensuring smooth transportation. Accurately measuring your trailer axle is crucial for proper functioning and even load distribution. This article will discuss three common methods for measuring a trailer axle: hub face, spring center, and overall length.

1.Hub Face Measurement:

The hub face measurement is the most common method for determining the length of an axle. This method measures from one wheel mounting surface (the hub face) to the other, across the axle’s centerline.

Steps to measure using the hub-face method:

– Ensure your trailer is on level ground and stationary.

– Remove the wheels from the axle.

– Measure the distance between the two hub faces where you removed the wheels.

This measurement will give you the hub face length of your axle, which is useful for determining replacement parts or when upgrading your trailer’s suspension system.

2.Spring Center Measurement:

The spring center measurement takes into account the distance between two spring centers installed on either side of your trailer’s axle. This method is essential for accurate suspension installation in leaf spring-equipped trailers.

Steps to measure using the spring-center method:

– Locate the point in which your leaf springs mount to each side of your axle (spring center).

– Use a measuring tape or straightedge to measure between these two points along the axle, lining it up with the center of each spring attachment

This measurement will help you when selecting replacement springs or installing new suspension systems.

3.Overall Length Measurement:

The overall length measurement considers the total end-to-end length of an axle beam, including spindles and any other attachments at either end.

Steps to measure using overall-length method:

– Ensure that both spindles are fully attached at either end of your axle beam.

– Start from one end (spindle) and measure directly across the axle to the other end (spindle) as accurately as possible.

Measuring the overall length of your trailer axle is helpful when determining available space for additional components installation or assessing the feasibility of a custom-made axle assembly.

Conclusion:

There are various methods for measuring a trailer axle, and choosing the right method depends on your specific needs. The hub face, spring center, and overall length methods are three common approaches that can provide accurate measurements for different aspects of your trailer axle. Remember, once you have measured your axle, consult with a professional or refer to an owner’s manual to ensure proper installation or replacement of parts.
