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.


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.


etrailer Axles

etrailer axles 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.

Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI Laboratories for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.


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"

  • 89 inch 3,500 lb Trailer Axle, Suspension and Hangers for Utility Trailer
    We do have 89 inch 3,500 lb trailer axles that come with idler hubs like the part # e65GR which is a straight axle or the part # e72GR which is a 4 inch drop axle. Both of these have their spring seats at 74 inches apart on center. Then for a leaf spring the part # e68SR is for a 3,500 lb axle and would work great. For a u-bolt kit to secure the axle to the leaf springs you'd want the part # APUBR-1 and for a single axle hanger kit with everything else needed you'd want the part # APS4. For...

  • Can Square Axle be Replaced With Round Axle & How to Find Right Axle
    You can replace your square axle with round axles, but you would need to replace both axles instead of just one to ensure you have the same length axles, which will ensure your suspension and tires wear evenly and avoid problems. In order 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; I have added a link below to a video which walks you through how to measure....

  • How to Change Spring Center on e65GR Trailer Axle
    In order to change the spring center on the Trailer Axle with Idler Hubs # e65GR you will need to cut off the existing spring seats. Once they have been removed, you will need to have # TRSS238 welded on to match your 72" measurement. If you have some kind of adjustable bracket I do not recommend using it. There should be no way for the leaf springs to move horizontally along the axle aside from moving the spring seat.

  • Replacement Axle and Leaf Springs for Pace American Enclosed Trailer
    Finding the correct replacement axle and leaf springs will require measuring and knowing your axle capacity. 2,990 lbs is not a typical axle capacity so I'm assuming that is the GVWR of the trailer. Try checking on the axle to see if you can identify it based on the axle tag. If not, you can measure the diameter or check the bearings to try to find the capacity. Once you have the capacity, measure from hub face to hub face to get the axle length. I have attached a video below which shows...

  • Installation of Idler Hub on etrailer e65GR Trailer Axle
    The # e65GR uses hub assembly # AKIHUB-545-35-K. I have attached an installation video of the hub below. Since the hub is pre-greased that means the bearings are already packed so you can ignore those steps. You will still want to add additional grease as part of the installation which can be seen in the video. The base type is lithium complex so you can use something like the # L11390.

  • Can 4 inch Drop Axle be Replaced with Straight Axle

  • How to Determine Replacement Axle Fixing Up Older Trailer
    Hi there Jason; thanks for that info and you did all the right measurements but unfortunately there is no hub that fits a spindle with those dimensions. This happens quite a bit on some of these older trailers so the best I can offer is replacing your axle with one that has a standard spindle and hubs. This will also make it easier to get replacement bearings and hubs in the future. I know it's not the answer you were looking for, but if you want to do this it's pretty easy to determine...

  • Replacement 3,500LB Axle and Leaf Springs For Vintage Trailer With Flattened Leaf Springs
    First I think you need to address the axle portion of your trailer since you have a fabricated lift block on a drop spindle axle. That axle likely is only rated for 2,000-2,500lbs by the look of it. By switching to a Straight Trailer Axle with Idler Hubs # e65GR you will be able to get rid of the blocks and those extremely long u bolts. This axle is also rated for 3,500lbs with a hub face to hub face length of 89" and spring center to spring center of 74". If your trailer has different...

    I do have a few potential solutions for you, but we do not carry an axle that will fit those specs exactly. The closest thing I have is part # e65GR. This comes with the 5 lug hubs (5 on4-1/2'). The hub face length is 89", so this may still work for your application. The spring seats are at 74", but I can sell you a few loose spring seats # TRSS238 and you could have them welded on wherever you need. Also, this axle is rated for 3,500 lbs so it will be a bit of an upgrade from the current...

  • How to Choose the Correct Axle Capacity for Trailer
    The axle capacity needs to be enough to handle the weight of the trailer plus whatever it is carrying. In other words, the axles need to meet or exceed the GVWR or gross vehicle weight rating. Assuming this is some kind of dump trailer with tandem axles I would say it weighs 2,000 lbs or more on its own. Add in the 9k lbs it can carry and you would be looking at 6k axles at a minimum, possibly 7k if the trailer is heavier. You will need to know the exact GVWR to select the right axle. For...

  • Replacement Hubs And Axles For A 2015 Keystone Hideout 27DBS Travel Trailer
    I can definitely help point you in the right direction. Axles and hubs are not custom fit, so we do not have a way to know axle/hub specs just by looking up a year, make and model. If only it were so easy right? That being said, the online owners manual for a 2015 Keystone Hideout 27DBS shows a GVWR of 7,865 lbs and a body width of 96". So it stands to reason that you likely have a pair of 3,500 lb axles underneath. Our 3.5K axles come in either a 89" long # e43SR, or a 95" long # 7359765-EB....

  • Replacement Hub Needed for Older Trailer Axle with M12649 and LM48548 Bearings
    While we do carry a replacement for your LM48548 bearing, listed as part # LM48548 on our site, none of our hubs use this bearing and from what I'm seeing your bearing combination is for very old trailer axles.
