Axle Dimensions

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle.

The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.

If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.

E-Z Lube Spindles Make Lubrication Simple

The E-Z Lube spindles on this axle are meant to work with E-Z Lube-compatible hubs to make lubricating your bearings quick and easy. Each E-Z Lube spindle has a zerk fitting on the end. And every E-Z Lube hub comes with a grease cap that has an easy-to-remove rubber plug. Just pop out the plug on the cap to access the zerk on the spindle. When you inject grease into the zerk with a grease gun, the grease will flow to both the inner and outer bearings of the hub, lubricating the bearings and forcing out old, ineffective grease. Once you see new grease beginning to be pushed out, you know that your bearings are fully lubricated. This means that you can lubricate the bearings without the mess of taking apart the entire assembly.

Dexters

Dexters are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. This axle is also built with drop spindles, which will lower the ride height of your trailer to allow for easier loading and unloading.

Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

• If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
• If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
• If D = 3", then the bolt pattern is 5 on 5"
• If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"
