Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

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 (when hubs are mounted on the beam).


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.


Hub Face and Spring Center Measurements on Standard Trailer Axle

Another helpful measurement to have is the flange-to-flange (C) length, which is measured from the outside of one brake flange to the outside of the one opposite. This length may be easy to obtain if you are replacing an axle, but it's important to note that this measurement is not the preferred method for determining which axle will best fit your trailer.


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.


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. The result of this underslung design is a trailer that rides a bit lower for quick and easy 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.

Bolt Pattern - Even

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.)

Bolt Pattern - Odd

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.)

Bolt Pattern - Side

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"

  • Converting 3,500 lb Torsion Axle to Spring Leaf Axle on Boat Trailer
    Hey Sam; thanks for the question and yes it is possible to go from a 3,500 lb torsion axle to a spring leaf axle on your boat trailer. You'll need to have new hangers welded on, as well as get leaf springs and, of course, the axle itself. For the hanger kit you can go with the Single-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front, 1-1/4" Rear # APS4 which gives you 5 inches of distance between the center of the axle and the trailer frame. For 3,500 lb leaf springs you can...

  • Identifying the Axle from a Home-Built Trailer
    There are a couple ways to determine what kind of axle you have. If there aren't any part markings on the axle or anywhere else on the trailer frame that list your trailer axle specifications, you need to measure your spindle with a calipers to get a precise measurement. I couldn't find a matching bearing based on the measurements you provided, so make sure you are using the right equipment to take these spindle measurements. You can also measure the axle diameter to get an idea of the...

  • How Much Upward Bend Should Trailer Axle Have
    While trailer axles do feature an upward bend like you are describing, there isn't a particular amount/measurement that is standard across the board. This bend in the axle is designed so that it will straighten under a trailer's loaded capacity. While I can't really say for sure if the bend you measured at the rear on your trailer is normal or not, the damage that it is causing to the frame is certainly cause for concern. This either indicates that there is indeed too much of a bend or...

  • Should Utility Trailer use Mobile Home Axles
    First, the most important thing I can tell you is that mobile home axles are made for one time use and should not be used on utility trailers; for that you would need an axle designed for use on RVs and to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center as in the diagram I have added; the other thing you need to know is the weight capacity of the axle you need, which...

Or the Timbren Axle-Less Suspension - Spindle Only - Regular Tires item # ASR5200S01 for 5,200 lbs axles.

  • Availability of the Dexter Axle # 35545I-ST-89 Without Hubs
    Sounds like you don't need the hubs that come with the Dexter Axle part # 35545I-ST-89 and you just want the axle. For that you would just want the part # T3584F-EZ-8974 that you referenced.

  • Can I Use the Dexter 3500-lbs Axle with Overslung Suspension
    Yes. The Dexter Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # 35545I-ST-89 will work with a trailer that has moved the leaf spring suspension to over the axles. Typically an axle has a slight bend in it because of the weight that it's going to bear, and will flatten out completely and be level to the ground. This won't affect the suspension that can be used with it. I've linked our entire selection of 3500-lbs axles for you to have a look at as well in...

    The Dexter axle part # 35545I-ST-89 is a 3,500 lb trailer axle so for a leaf spring that would work well with that you'd want the # e45SR which is the same rating and is 25-1/8 inches long. Then for a tandem hanger kit you'd want the # AP233-H248 and the U-bolt kit part # CE23002.

  • Can Brakes be Added to Second Axle in Tandem Axle Setup
    You can definitely add brakes to an axle without purchasing another one. The easiest thing is if your axle already has a brake mounting flange installed on it. If your axle doesn't then you can have one welded on, but we typically recommend replacing the axle in this case just because you can have the peace of mind that the flange was done professionally. I am attaching a link to some helpful articles on adding different types of brakes to an axle that you can check out. I am also attaching...

  • Recommendation For Replacing A Dayton Fayette 9222 Hub
    Having a 1.25 spindle, it can be a few bearings that will fit. However, there will not be a hub that uses both an inner and outer bearing of this size. With that said, I highly recommend replacing your axles with something that will use a more common bearing combo. Doing this will require a few things.

You will want to pick leaf springs that are as close to the axle capacity as possible. You will want to also measure the distance from eye to eye of your old...
