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.

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"

Video Transcript for Dexter Trailer Axle with Idler Hubs Review

Speaker 1: Today we're gonna be taking a look at the Dexter 3,500-pound trailer axle with idler hub, offering the 5 on 4 1/2 inch bolt pattern. The part number is 35545I-ST-89. Now, to ensure that this is gonna be an appropriate fit for you, there are a few measurements you'll want to check. The first is gonna be the spring center, so it's the center of the spring here to the center of the spring on the other side. That should be 74 inches. The next thing that you'll need to confirm is your hub face measurements.

That's gonna be the flat section that your wheel mounts on each side, from that to that on the other side, you want that to be 89 inches. As long as you're at that 74 and 89 on a 3,500-pound trailer, should be good to go.The axle's also gonna include a brake flange on each side. This is designed so you can bolt up either electric or hydraulic brakes. We're gonna be actually putting a set of disc brakes on this trailer, but that gives you a nice option, if maybe your trailer doesn't have brakes now and you want to upgrade, or you want to ensure that your current brakes are gonna fit the axle, got our flange there. That's gonna be 82 5/8 from the flange here to the flange on the other side.

That's pretty typical.Here's a good look at the spindle we're gonna have in the axle. So the seal provided will ride along that, it's gonna prevent any grease from coming out. Got our inner bearing surface here, our outer bearing surface here. As you can see, everything's nice and clean, brand new, ready to go together. The seal, both bearings, the nuts at the end, the keeper, everything's gonna be included.Now here's a good look at your hub.

As you can see, we've got the cast iron hub, it's gonna give us excellent strength and durability. And that's gonna have the races already installed inside, so our bearings are gonna match to that. Of course, the five studs, these are gonna be 1/2 inch in diameter, and you do get brand new lug nuts to go on each one. These are all on here backwards, this is the way it came, you want the cone to face the tires, so keep that in mind.Now, when replacing your axle it's a really good idea to also replace the U-bolts. These are a pretty cost-effective item you can get and ensure that you're gonna have excellent, excellent hold with your axle to your springs.

And you can see this is going on a four-spring pack. It comes with the new lower plate and also four new flange nuts. That allows you to secure that in, keep everything locked tight so we don't have any issues for a very long time.You can see we've got a little bit of an arch to our axle, a little bit of a curvature. That's to help achieve zero camber. So essentially, our tire will be straight up and down, not tilted out or not tilted in at the top. That allows your tire to lay flat on the ground, it's gonna give you excellent contact to the ground, which will equal good stability.We also have a straight spindle design. So essentially, what that means is that the center of our spindle is in line with the center of our axle. Also, this axle's designed to be overslung. You'll see our spring mount here. It sits down on top of the spring, that really brings the level of our trailer down a little bit, makes it easier to load and unload. The opposite of this would be an underslung axle. So our axle would be bent the other direction and it would mount down here to the bottom. So if your axle is configured like this, sitting on top of the spring, this is gonna be the guy for you.Now, also with your axle you're gonna get a one-pound tub of marine-rated grease from Lubrimatic. Basically, what this is, it's just a basic trailer grease, but it has corrosion inhibitors built in. Most oftentimes, this type of axle you see on a marine trailer. You can also see them on utility trailers. The good news is, this type of grease is gonna work in both applications. You wouldn't want to use a standard trailer grease on a marine trailer, 'cause if that water gets in there, it's really gonna hurt your spindle inside and cause rust and corrosion issues. That's where we have the big benefit with this.Now, to begin your axle installation, you're gonna need to remove the tires from both sides. And you'll have the option at that point to either drop down the leaf spring or just pull down one of the hubs, which is what we're gonna do. We'll pull this one here, but first let's get the tire out of the way.Next we need to take the cap off the end of the hub. Now, this is gonna depend on the type of axle you have. This one happens to have a bearing buddy in it. Some of them may just have the metal cap that's pushed on there, some of them may have the easy lube cap. Just gonna depend on your application. What we want to do is just start tapping around the outside, and you'll see this gap kind of begin to get a little bit larger here. It'll come off. Now I'm gonna remove the grease, find our pin so we can remove the hub. So there's our cotter pin there, end of it's here. So we need to straighten that out, use a pair of pliers.Now we've got our nut here. These are generally on pretty loosely, so just a pair of channel locks there. Get that nut taken off. Behind it you've got a little washer, that holds that bearing in place. Take that out, get our bearing. Then we can take our hub off. Typically your inner bearing and your seal are gonna come off with the hub, but clearly this one had some leaking issues. So we'll have to pull those off manually.Now we're gonna clean this grease off here just so we don't get it on anything. And now we're gonna remove the four nuts on the bottom here that hold our axle down, and they hold the U-bolts here. When replacing an axle, generally you're gonna replace these as well, just because these can kind of stretch over time. So if these nuts won't come off, you can also just cut your U-bolts on each side.Now we're gonna lift up on our axle and we can get it slid out. Now, to get our new axle in place, we want to pull the hub off of one side here, so we can slide it in just like we did before. Use the same technique to get this removed. Gonna tap it around that outside edge. There.Now we've got our keeper here, just work around the edge, get that popped off using a flat blade screwdriver. Back that nut off. Then we'll pull our assembly 00:07:34. Now, you can see the red grease in there, got it on our bearings, on our seal, everything. We're gonna be switching this out, you can see our retainer washer there, hang onto that. This is a boat trailer, so we need to use marine grade grease. But even in a utility trailer application, switching out this red grease for blue grease, it's gonna give you a higher drop point so that grease is able to absorb more heat. So it might just give you a longer-lasting effect. Or utility trailers tend to sit around for a while, moisture can get in the hubs, and that'll help prevent it.Now we'll get our new axle slid in. You can see we want that, it has a little hole in the bottom of it, to rest right on top of that tab that sticks up. Now we're gonna grab our new U-bolt kit and place these down and around, just like our old U-bolts were. This part number is APUBR-1, designed for the 2 3/8 diameter axle. Now we can place the bottom bracket up on the U-bolts. You can see the hole here in the middle, that's meant for that nut to come down through. Then in each position we'll install one of the flange nuts.Now we'll go through, and we're evenly gonna tighten down our bolts, get them snugged up first and then we can torque them. For these nuts you'll want to use a 19-millimeter or 3/4 inch socket. Notice we're tightening them evenly but in a crossing pattern.We're gonna get our spindle cleared off here. And in this situation we're gonna be adding brakes, but if you are just purely doing an axle replacement, at this point you're just gonna reverse that process we used in disassembling our old axle. The only real difference will be that we'll have, instead of a cotter pin here at the end holding it, we're gonna have that keeper that just slides over.Now we're gonna take you through the process of how to pack your bearings. You can see there's a wide gap here. We're just gonna force grease through. We're gonna capture it and then push. Capture and push. There's no real good, clean way to do this. You can use a bearing packer, but a lot of people seldom have to do this. This is a maintenance thing, you will want to do it periodically, change out the grease in your hubs. But with the axle kit you're gonna have plenty of that grease on hand, so should probably last the lifetime of the trailer, really. And we're just gonna force that grease in until we see it come out of this top side. See those little bubbles start to form. You want to do that all the way around the outside.Now once we've got that fully packed all the way around on both sides, we can get our hub installed. Now, something else I like to do is eliminate any chance of there being an air pocket inside of our hub. So I take a good amount of grease, I'm gonna put it all the way around the inside, both front and back. I want it to be good and fully coated all the way through. It'll just keep any moisture from getting in there if it gets warm and condensation or anything like that. Slide that over our spindle, make sure it slides onto your seal surface there. Try to pack as much in there as we can. Now we're ready to take care of our outside hardware.Now we'll take our bearing, we want the smaller side to face in. Slide that in. Now we've got the washer. That flat spot's gonna match up with the flat spot on the spindle. That'll go in, then we'll start threading on our nut. Now we can use a pair of pliers to finish tightening that down. When you get it overly tight like we've got it now, you can see that won't spin at all. So what we do is get it down there tight so we know we've got rid of all of our movement, then we'll back that off a little bit, it's gonna give us a little bit more of a free spinning, free moving situation. Just clean that grease off and we'll get our keeper in place.Here we've got that little tab on our keeper, we want that to be on the flat spot of that spindle again. We just kind of push it over, you might have to tap it just a little bit if it doesn't go on with just a little bit of pressure. Rotate your bolt, or rotate your nut just a little bit there. I just want to make sure that's all the way in against that nut, and that'll prevent it from backing off, but still give us the play we need.Now, one thing you do want to check is end play. So we want to push this in and pull out, and make sure we don't feel any movement. Now we're gonna put the end cap on. This is the one supplied with the axle. On a marine trailer, we do recommend bearing buddies. Basically it's gonna give you a grease hook 00:13:14 here on the end with a spring that'll just gently force that grease in there so you know you're gonna have fully packed hub all the time. But whether you're using that type or this type, you just want to line it up, kind of get it square, and then just start tapping it a little bit. If you don't have a dead blow hammer you could use a little piece of wood and then tap on it with a steel hammer. You just want to make sure that edge goes all the way in against your hub.And that's gonna complete our look at the Dexter 3,500-pound trailer axle with the idler hubs, part number 35545I-ST-89.

  • Measuring for Replacement Dexter Axle
  • From your photo, it looks like you have a Dexter axle, part number 51955. From my research, it appears this is likely a 3,500-lb axle. However, the weight capacity should be listed on the axle itself, so it would be best to confirm this before purchasing a replacement. You'll also need to know the axle length. I've attached a photo showing where to measure your axle for the correct length. I've also included a link to our axle product listings. Once you know your measurements, you can...

  • How to Find the Length of a 3,500 lbs Dexter Torsion Axle
  • I just want to make sure when you say track measurement, you mean the center to center distance between the tires. Another industry term for this measurement is the Hub Face measurement. The best way is to measure from tip-of-spindle to tip-of-spindle and subtract 4-3/8" and that will give you the hub face measurement on Dexter torsion axles. Another way is to measure the brake flanges outside to outside and add 6-3/4" and that will give you the results.

  • 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...

  • Increasing the Load Weight Capacity for My 5x10 Trailer
  • First thing I would recommend would be to see if you can identify the weight capacity of the axle by locating a tag near center of the axle. If you have a 2,000lbs. axle it would be possible to upgrade to a higher capacity system. It is important to note that this will not increase the weight capacity of your trailer's frame, which is something you will be limited by. Even after upgrading all the parts, you could attempt to reinforce the frame by welding on more steel but unless you...

  • Trailstar Trailer Axle is Bent Causing Tires to Wear Quickly
  • The problem may not be your axle at all. Is it bent upwards or downwards towards the ground? If it is upwards then that is normal but down means it does need to be replaced. The reason axles have an upward arc to them is so that when a load is placed on them they straighten out and your tires run evenly. When the inside of the tread on your tires wears on the inside that is a good indication that you are overloading the axle which is causing it to bend down too much. Try checking...

They usually have odd spindle sizes on them that make them incompatible with standard trailer hubs. Attached is a page that has all of the axles we have with the correct hubs included. You will want to determine which will suit your trailer based on the overall length axle you want from hub face to hub face, then select the distance between...

  • Methods to Determine Actual Trailer Weight and GVWR
  • If you can contact the trailer manufacturer with the VIN from their product they should be able to tell you a good bit about it including its GVWR (gross vehicle weight rating), which is the most it can weigh when loaded. The empty trailer's actual weight should also be available. The characters in a VIN do denote certain specific information, as shown in the linked photo that displays an example VIN. But actual weight and total weight capacity is not among them. Often trailer axles...

  • Where to Measure to Pick Out Trailer Axle Replacement
  • You would need to measure from the hub face to hub face and then from the spring mount centers to pick out the correct axle to fit your trailer. I attached a picture that shows where these measurements are.

  • Can Custom Axles be Ordered or is there an Alternative to Straight Trailer Axles
  • Straight axles can be made to order by visiting a local trailer/tractor supply store but I have a better alternative. I recommend switching to a Timbren axle-less system # ASR3500S05. This system takes the place of the axle and the suspension. The rubber suspension requires no maintenance and won't corrode like traditional leaf springs which will save you money over the life of the trailer. I have linked a video review for you.

  • Looking for a 3500 Pound Trailer Axle with or without Hubs
  • All of the 3500 pound straight axles we carry measure 89 inches long hub face to hub face and 74 inches long on center from spring seat to spring seat. You would have to order an axle from a local tractor or trailer supply store to your specifications. The other option is to use axle-less suspension such as # ASR3500S05.

  • 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.

  • Replacement Axle Needed for a 1996 Astro Trailer
  • When replacing your trailer axle the measurements that are needed are the Hub Face (A) and Spring Seat (B) measurements (see attached photo). Aside from that the only other thing you really need is the weight capacity of your axle. We do offer a small selection of traditional axles like part # 35545I-ST-89 as well as Timbren Axle-Less systems like part # A35RS545E that you can choose from. I have attached a link to our axle choices but if none of our traditional options match up to your...

  • Replacement Axles Needed for 2006 EZ Loader Triple Axle Trailer with 74" Spring Center Measurement
  • We do have a selection of axles with a 74" spring center measurement but you will want to measure your hub-face-to-hub-face measurement as well to make sure that it is 89" before ordering (see attached picture). These are all rated for 3,500 lbs and come in a variety of ways. For example, part # 35545E-ST-EZ-89 comes with electric brakes and has hubs with a 5 on 4-1/2" bolt pattern, part # 35545I-EZ-89 comes with idler hubs that have a 5 on 4-1/2" bolt pattern, and part # T3584F-EZ-8974...

  • Recommended Components Needed To Add Axles And Brakes To Tandem Trailer
  • The first thing to consider is what the trailer is to be used for. If it is a boat trailer then electric brakes would not be the way to go, as water and electric do not work well together. I will make recommendations with the options you listed you want. Our 3,500 lb axles have the spring seats at 74 inches. If it is not a boat trailer the axle I recommend is the Dexter Trailer Axle w/ Electric Brakes, part # 35545E-ST-EZ-89. This axle measures 89 inches and includes the Includes electric...

  • Adapting a 89 Inch 3,500lbs Trailer Axle # 35545I-ST-89 for Overhung Application
  • Yes, you will need a set of the # TRSS238 Spring Seats which will fit your 2-3/8 inch round axle to adapt your # 35545I-ST-89 89 inch 3,500lbs axle to make it compatible with an overhung application. You will want to make sure you take it to a local qualified professional welder to install the spring seats at exactly your 68 inch center. I have linked the correct spring seats to this page for your convenience.

  • 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...

  • How to Choose an Axle to Replace Torsion Axle on a 1999 Bantam Travel Trailer
  • I do have a way for you to measure for an axle on your 1999 Bantam trailer. The hub-face measurement (A) would be the same as what you have now and the spring-center measurement (B) is taken from the center of one side of your trailer frame to the center of the exact opposite side of the frame. The spring-center is where your leaf springs will be hanging. Since axles like the Dexter # 35545I-ST-89 have the spring seats already welded on it is important to have an accurate spring-center...

  • Recommended 3,500-lb Axle-less Trailer Suspension System
  • The Dextar 3,500-lb axles we offer are not the Torflex brand. The beam axles we offer are a straight beam like part # 35545I-ST-89 with idler hubs or part # 35545E-ST-EZ-89 that has electric brakes, but I do have another option. I recommend the Timbren axle-less system. The axle-less systems we offer will work on any trailers and eliminate the need for springs and hangers and equalizers. They come with varied set-ups so you have a very flexible option. I have attached a link to our...

  • How to Choose Replacement Trailer Axle, Hubs and Leaf Springs for 2006 Magic-Tilt Boat Trailer
  • We do not have a way to look up the original parts on your Magic Tilt BV16XWW boat trailer but we can help you with identification to allow selecting a replacement axle, hubs and leaf springs. For the axle you will want to find the trailer VIN sticker that indicates the axle weight rating, or you can check the axle itself for this information. We carry beam axles up to a 3500-lb rating, shown on the linked page, and some of these come with hubs as with part # 35545I-ST-89. We also offer...
