Trailer Axle Measurement Guide – TowParts.com
When working with trailer axles, a few key measurements are essential to ensure proper fitment and performance. Accurate measurements are crucial to avoid unnecessary wear, damage, or safety issues. Below, we’ll explain how to measure your axle with confidence.
Getting Started
To make the process easier, it’s best to remove your tires and wheels before taking measurements. This allows for more precise readings. If removing them isn’t possible, you can measure from the center of one tire to the center of the opposite tire. Having a friend assist by holding one end of the tape measure is helpful but not absolutely necessary.
Hub Face Measurement
What is it?
The hub face measurement is the distance from the outer face of one hub (where the wheel mounts) to the outer face of the opposite hub. This is the most important measurement when replacing or upgrading an axle.
How to measure:
1.Hook your tape measure to the outer face of one hub (the side facing the wheel).
2.Extend the tape measure across the axle to the outer face of the hub on the opposite side.
3.Be careful not to measure to the inside face of the hub—measure only to the outer face for accuracy.
Spring Center Measurement
What is it?
The spring center measurement is the distance between the centers of the leaf springs. This measurement is critical for proper axle placement and load distribution. If the springs are installed incorrectly, it can lead to bent axles and unsafe towing conditions.
How to measure:
1.Have a friend hold one end of the tape measure at the exact center of one spring.
2.Stretch the tape measure to the exact center of the opposite spring.
3.If you’re working alone, hook the tape measure on the outside edge of one spring and measure to the inside edge of the opposite spring. Subtract the width of the spring to determine the center-to-center distance.
Tips for Accurate Measurements
•Always double-check your measurements before ordering or installing a new axle.
•If you’re unsure or need help, reach out to our experts at TowParts.com for guidance.
•Use a high-quality tape measure with clear markings to avoid errors.
Pro Tip: Keep these measurements handy when contacting TowParts.com for axle replacements or upgrades. Our team is happy to assist you with any questions or concerns!
Trailer Axle and Hub Selection Guide – TowParts.com
Proper axle positioning and hub selection are essential for building or repairing your trailer. Here’s a detailed guide to help you make the right choices with confidence.
How to Purchase the Correct Trailer Hub or Drum
Selecting the right hub or drum is a critical step in repairing your trailer axle. Follow these simple steps to ensure you get the correct fit:
Step 1: Remove the Hub or Drum
Carefully remove the hub or drum from your trailer axle. This will allow you to measure and inspect the components for identification.
Step 2: Measure the Bolt Pattern
Determine your axle’s capacity by measuring the bolt pattern. This step is crucial if the capacity is unknown. Use a bolt pattern diagram to identify the correct measurements.
Helpful Tip: A 5-lug bolt pattern can sometimes be tricky. Use our bolt pattern guide for accurate results.
Step 3: Identify the Bearings and Seal
1.Remove the front and rear bearings and the seal from the hub.
2.Look for numbers stamped on the bearings. These numbers correspond to the spindle size.
3.If the numbers are not readable, measure the inside dimensions of the bearings and seal using calipers.
4.Refer to our bearing measurement guide for step-by-step instructions.
Step 4: Select the Best Hub or Drum for Your Needs
Once you have the measurements and information, choose the hub or drum that fits your requirements.
