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.

Do you have a question about this Trailer Axle?


  • 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...

  • We can come pretty close to the dimensions you mentioned. Dexter Axle # T3584F-8974 is a 3500 lb capacity axle with a hub face to hub face dimension of 89 inches and a spring seat center to center measurement of 74 inches. This isn't the exact spring center dimension you were looking for, but it would be very easy to grind off the old seats and weld replacements like # TRSS238 into place. The standard spindles are compatible with a L648149 inner and a L44649 outer bearing. If you prefer...

  • 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 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.

  • 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).
