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.


Dexter Axles

Dexter 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.

My utility trailer bearings locked up and welded to the spindle, along with the seal. Repair would have cost as much as a new axle. Ordered this axle Thursday night around 10pm, Arrived Saturday morning around 10am. They were running a special and regular shipping was free but I paid for 2nd day delivery which was discounted. Actual product was as described, wrapped well end to end with rubber protectors over spindles. Installation was a snap and took about 20 minutes start to finish with no help. Still waiting on hubs to be delivered but I am expecting the axle to do what it is supposed to. I will definitely use etrailer again, and should I need another axle, I wouldn't think twice about ordering this one again. Excellent business with an excellent product. 777619

Perfect fit, nice axle and fast delivery. I liked it so much I ordered another a day later to replace the front axle. My 30 yr old tandem trailer's axle broke at the wheel, so I went to a local store which doesn't stock them anymore. Could of ordered a so so axle for $94 + $28 shipping and wait 2 weeks but needed it fast. I went to a major trailer sales & service shop and told "maybe we could get one for $250" with no call back. I decided to check out etrailer and was surprised to see Dexter axles that fit my trailer for $140 with FREE shipping in 3-4 days! Ordered Sat. night, got it Wednesday afternoon, and installed it (with brakes) in an hour. Only problem I had was determining if spindles would fit my hubs. They stated "1/16th spindle" and must be industry talk but french to me. So I had to look up bearing #'s they listed to check bearing sizes to make sure they fit my hubs. A little more time but not a deal breaker. The best part was the huge difference in ride with just one new axle. Always had bouncing loaded or not, but now with just one axle the ride is smoother no load and with my 4000 lb tractor on it. Can't wait to get the 2nd axle on that arrived today. First two pics show the difference between the old straight axle and the new dexter axle. The third is a pic of my 2nd axle, oh well. Etrailer is my new go to place for trailer parts. I have 7 trailers. 661643

  • Recommended Replacement 3,500 lb Axle for Carson Trailer with 88" Hub-Face and 74" Spring-Center
    We do have a replacement 3,500 lb axle for your Carlson trailer as well as hubs that fit your description. The axles that we carry have an 89" hub-face and 74" spring-center measurements so since the hub-face dimensions are only 1" off of what you measured these will work well for your application. I'm pretty sure that your axle has the 89" hub-face measurement as that is extremely common (and measuring the hub-face is a little difficult) but even if our axle hub-face is 1" wider there...

  • Replacement Trailer Axle With 89 Inch Hub Flange To Hub Flange Measurement
    In order to replace your trailer axle you can use the Dexter Trailer Axle Beam with EZ-Lube Spindles part # T3584F-EZ-8974 for a 3,500 lb capacity, part # 8327820 for a 5,200 lb weight capacity, or part # 8327830 for a 6,000 lb weight capacity. These axles all have the correct hub face measurement but you will need to have the spring seats moved to match that of those on your trailer. Based on the measurements that you provided of your stud centers, you have a 5 on 5-1/2" bolt pattern....

The Dexter Trailer Axle Beam with EZ-Lube Spindles part # 7359765 has an 95" hub face and a 80" spring center.

  • Replacing the Axle on a Gooseneck Horse Trailer
    An axle flip kit like part # K71-384-00 will raise the trailer the diameter of the axle plus the height of the leaf spring pack. I do have options for you but rotating the axle to where the bend faces the other direction is not one of them. The bend in the axle will actually straighten out once a load is placed on the trailer and if this was reversed, the axle would lose capacity. Now from this point forward you have two options both of which entail replacing the axle. Since your current...

  • How to Determine Correct Replacement Axle
    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 as in the diagram I have added. However, from the numbers you added it seems likely that your old axle is 85 inches hub face to hub face and 68-1/2 inches spring center to spring center. You will want to verify that is correct, but if so we have an option, but not for a standard axle. Instead, you would need...

  • Where Do I Position My New Trailer Axle?
    When positioning a trailer axle or adding an additional axle, the key is to make sure that the axles are located in just the right position so that roughly 10 to 15 percent of the total trailer weight is placed on the tongue. Finding the correct axle location can take some trial and error, so it is best to mock up the locations for all the suspension components until you know everything is in the right spot. I have a diagram and a help article attached that will show you how to recalculate...

  • How Can You Determine Axle Load Capacity on a Dexter Axle
    I reached out to my contact at Dexter and based on your serial number, they can't really narrow it down. It is an older axle that was produced in a plant that has since been closed. All they can tell me is that it is between 2K and 8K capacity because it came from that plant. Do you have a GVWR sticker on your trailer? Does it have brakes if so are they 10 inch or 12? We can get really close with this info if not confirm load rating. Another way to narrow it down is with spindle...

  • How Much More Clearance Under Trailer Using Torsion Axle With Negative Angle
    In order for you to realize more clearance under your trailer, using torsion axles with down degree angles will give you more clearance. On a system that has a 10 degree up axle, the center line of the spindle to the bottom of the trailer frame is approximately .96 inches. That is based on a newer system. If you have an older system on your trailer that measurement may be much less. For a 10 degree down you would have a difference of 2.08 inches. For 22.5 degree down, the difference...

  • Replacement Axle for a 1994 Jayco Eagle 8 with Dexter Axle
    It sounds like you will need a 2,000 pound axle. We do not carry the torsion straight axles though. We do have axle-less systems that work the same as torsion axles. I have included a link to them for you to view. The great thing about the axle-less systems, besides the better ground clearance, is that you don't have to have a specific axle length and in your case you would not have to add suspension components like you likely would if you went to a straight axle.

Based on the deep scoring on the spindle it certainly does appear that this hub suffered a catastrophic bearing failure that in turn took out your spindle. You can replace your 3500-lb Lippert axle with another brand or you can have new spindles welded on.

  • Is Trailer Axle Bow Normal When Loaded
    You are correct that trailer axles feature an upward bow in them to compensate for the trailer's loaded weight. As more weight is put onto the trailer this bow will indeed flatten out (so the axle profile will look different when the trailer is completely empty compared to when it's fully loaded for a trip). If the axle is flat this doesn't necessarily mean that it's overloaded. It's more likely that it's just supporting around the maximum weight that it's designed to handle. It's always...

    Of the axles that we carry the part # T3584F-EZ-8974 that you referenced would be the closest one we carry to what you would need. The spring center measurement is the same at 74 inches. The issues is that this axle measures 89 inches from hub face to hub face so it would be 2 inches shorter than what you currently have. If the wheels and tires could be an inch closer to the frame on your trailer on either side without causing interference this axle would work well for you. Otherwise...

    The Dexter Trailer Axle Beam # T3584F-EZ-8974 you referenced is an underslung design and you would need an overslung axle, though there is still a way for you to use an underslung axle. I assume you used an over/under conversion kit such as # K71-384-00 to move your leaf springs to the top of your axle. If so, you could still use those U-bolts and Spring Seat for Typical 3,500-lb, Round Trailer Axles with 2-3/8" Diameter # TRSS238 to place this axle on top of your leaf spring. Or, as...

    You did not specify which way your axle was bent, but a trailer axle such as the Dexter Trailer Axle Beam # T3584F-EZ-8974 should have a slight upward bend, as you should be able to see in the accompanying photo of this axle installed.

  • Axle Recommendation for a Trailer for Best Ground Clearance
    If ground clearance is your primary concern I have a great solution for you. Instead of a standard axle like the part # T3584F-EZ-8974 that you referenced you would want a Timbren Axle-Less system like the part # ASR35HDS02. This setup has the same capacity as the axle you referenced, does not have an axle that runs under the trailer, has a 4 inch lift built into it, and has wider clearances for larger off-road tires. For a hub for this setup you would want the part # 42655UC1.

  • How Does EZ-Lube Spindle Grease Hub Components
    The EZ-Lube spindles have a hole in the spindle so that it fills the hub components from the back of the inner bearing. This forces air out of the hub area and will disburse the grease toward the outside of the hub on the grease fitting side. I have attached a photo of an EZ-Lube spindle that shows the hole where the grease exits.

  • What are Overall Dimensions of Typical Trailer Axle
    There isn't a set dimension for that on trailers. Typically axles are custom ordered to the specs needed.

For example, we have the 3,500 lb trailer axle part # T3584F-EZ-8974 which has 89 inches from hub face to hub face and then 74 inches from spring seat to spring seat.

  • What is Causing Wear on Outer Edge of Passenger Side Tire on Trailer
    I first recommend checking to make sure the tire is properly inflated to the maximum psi listed on the tire's sidewall. If the tire is under-inflated, the sides of the tire tread will wear quickly. If the tire is inflated properly, then it's very possible that there is an issue with the trailer's suspension components or axle/spindle. Since the wear you noticed is only on the outer edge of the tire, this might indicate that the spindle is not parallel to the ground. There could be a...
