6 Values That Need to Be Measured on the Trailer Axle
The trailer axle is an indispensable part of any type of trailer. If its value is not accurately measured, it may cause some failures in the matching new axle during driving. The following are the six values that need to be obtained to measure the trailer axle.
Load capacity
The axle’s load rating needs to support the maximum gross vehicle weight (GVW) rating. If your trailer has multiple axles, you need to divide the GVW by the number of axles to help you determine each axle’s minimum load capacity.
Track length
You determine this by measuring the distance between the center of one tire to the other center, which is also called the axle hub face. You can obtain a more precise measurement by calculating the distance from one hub mounting flange to the other flange, which is the mounting surface. It’s where the wheel studs are.This measurement is also called the track length. Remember, only measure hub face to hub face to determine this measurement. If you measure from the back of the hub or the brake flange, you will end up with an incorrect measurement.
Drop
This measures from a spindle’s centerline to the main axle tube’s bottom. Remember, straight axles have no drop.
Spring center
This measurement is crucial. If you don’t get it correct, or do it badly, you may bend the axles. The measurement is between the center of one spring to the center of the other spring. If you can’t find a friend to give you a hand, you can cheat by hooking a tape measure to the outside of one spring and pulling it out the inside of the other spring.
Total length
Determine this measurement by taking the distance between the two ends of an axle’s spindle.
End-to-end spindle
To get this measurement, you need to take the wheels off both sides of your trailer. Then, place your tape measure on the outside of one spindle and pull it to the same point on the opposite spindle. Tell the salesperson taking your order you are giving them a tip-to-tip spindle measurement. If you’re taking this measurement for a boat trailer, you need to subtract five inches for trailers weighing 2,000 to 3,500 pounds. This will give you your hub face measurement.
If you do not make precise measurements when you buy, but only order according to your understanding and needs of the trailer, it may lead to the wrong choice of trailer axle.
