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.

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.

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 Idler Axle with Idler Hubs Installation

Speaker 1: Today we're going to be taking a look at and also showing you how to install the Dexter Trailer Idler Axle with the idler hub. These have the easy lube spindles and offer the four on four bolt pattern. 60 inches long and with a 2,200 pound capacity the part number is 20440I-EZ-60.Now to verify that this is going to be the appropriate axle replacement for you there are two measurements that you want to get. The first they call spring center. So that's going to be from the center of the spring on this side, to the center of the spring on the other side. This axle offers a 48 inch what they call spring center to spring center measurement, so you want to make sure that yours matches that.

The second is going to be the hub face to the hub face. So you want to get this measurement while the hubs are still on the axle.You're going to measure from the flat spot where your rim makes contact with the hub to that same spot on the opposite side. What we're looking for is 60 inches.Now to install the spring on your axle we're going to use U bolts to connect it. So our springs going to fit around the underside. We'll have a plate to go underneath and two U-bolts to hold it.

Now we recommend using a new U-bold kit. The larger hole in the middle is going to accept that small tab that sticks off there. The top portion of the bolt fits right into the bottom. The spring perch there. Bring that through and then we'll just take the provided nuts, we'll snug these down once we have our axle in position and we know that it's hanging in the way we want it.Now we can get our axle put up in position once we have that done on each end.

You'll see here on the back side is going to be the area the slipper portion will slide into and then we'll rotate it up into position and we'll use our bolt here in the front. Now we just want to rotate that up into position and once we align our hole we can slide through our bolt. You can see that's going to fit right through that bracket up here on the spring eye. It'll go through our bracket, through the spring eye, come out on the inside.Just want to keep in mind you do want a little bit of movement. You don't want to squeeze that bracket down so tight that it's pulled against the side of the springs.

You want those to be able to move a little bit.Now on the back side of the bolt right there at the head, you'll see those lines that are on it. Those are designed to engage the bracket and keep our bolt from turning so you don't want to turn the bolt side. We're going to tighten this down using the nut side only.Now once the spring eye bolts are in place you want to kind of tap your axle. Make sure that your U-bolts are sitting straight up and down and we'll start to tighten these down evenly.Now we're going to go to each one and we're going to begin to torque them down. Now typically what you're looking for is torque to yield, is what they're called. So we're going to torque these just until we see our plate start to deform just slightly. That'll give us the proper tension on those U-bolts so we won't have to worry about them backing off.Now whether you've just got the replacement beam or the kit you're going to have to assemble your bearings, your hubs, everything, get it put in. Now the hub kit is going to of course have our hub. You see it's got black powder coat finish on it. Has our four studs. These are on a four on four bolt pattern which is going to be very, very common. Inside you'll see the races the bearings are going to run on. It's really nice to get a full replacement kit when you do replace axles just because you're starting right back from scratch so everything's going to be brand new and fresh. It's going to come with an inner and outer bearing for each side.Of course you'll have new lug nuts. You're going to have the new dust cap with the removable plug that allows you to get into the easy lube greaser, and we've got the bushing, the nut and the keeper that kind of holds all that in place and keeps it from backing out which on the end of the hub, so this really gives you an excellent way to get everything replaced and then once you have your bearing in the back side of your hub, you've got the new seal that's going to keep all the grease inside and not let it seep out.Now we're just going to use some regular red style high temp grease. It's important to use high temp grease. You don't want to use a universal or anything like that just because as fast as this is going to be turning it builds up a lot of heat, but we'll take one of our bearings. They're both going to be the same and then you can use a bearing packer, there are a few different methods for packing bearings but these being as small as they are it won't take long.Just get a rub on your hand and you just kind of work it in that crack between the inner and outer portion and as you do that it's going to come out of the top, right up in this area. You just want to make sure you do that all the way around. But once you've got that coming out all the way around the top edge here, we'll call that one packed, that's going to go right into the back side of our hub. We'll show you how to put that seal in now.Now to get our seal in place we're going to be using a seal driver. This is part number PTW83020. Just gives you a nice flat surface. It's pretty easy to work with. If you don't have a seal driver around or you don't want to make the investment in it, you could also, instead of placing my seal driver on the top, you could also use a block of wood. So you're just going to place it on there, begin to tap it down in place. You want to get it started all the way around. Once you've got it started all the way around, just drive it home evenly. Just like that.Now inside the hub you can see just a little recessed area. I like to take a wad of grease and get it inside there all the way around. It'll just save you some time with a grease gun filling it up later. Now we're going to slide that on, place in our outer bearing, taper side in. Now we can slide on the bushing and that's going to match the flat portion on the spindle there. Now it's time to thread on our nut.You see we've got free play there. We're going to make sure that we compress our bearings in there way. Some slip joint pliers. You'll feel that tighten up a little bit. We don't want it to be overly tight so we'll back that off just a little bit. We feel the proper tension then it's time to slide on the keeper. Now this is going to go right over the nut, you can see the little tab that sticks in. That's going to go in between the flat spot and the nut. So that is going to slide in that little slot right there.Now we'll use the grease gun, we're just going to fill until we see grease starting to come out around the outside of our bearings there. All right now we just want to place our cap on. We're going to begin to tap it in place just like we did with the seal you want to make sure you get it started all the way around and you can put it in the rest of the way.That little lip should go right up against the outside of the hub and you'll place your rubber capt in. You'll see that's going to cover our grease cert there to keep any moisture or debris from getting in there and causing us any trouble.Now at that point you can put your tire back on. Torque down your lug nuts properly, you'll be ready to hit the road. You remove this cap, inspect the grease inside and when needed add a little bit more.That's going to complete our installation of the Dexter Trailer Idler Axle with idler hubs. The four on four bolt pattern, 60 inches long.

The axle and springs have worked great! They replaced parts that were beyond worn out, so they have given a new life to the trailer. They were straight forward to install, and your videos were helpful. 563373

I ordered this axle as a replacement for the one on my 1996 Haulin' 4x8 utility trailer. I'd neglected to maintain the bearings and when one went it destroyed my axle. This axle was an exact fit but the spring seats needed to be moved to the top of the axle. I ordered new seats and U-bolt mounting kit as well as the axle. I found a welder to remove the original spring seats and weld the new ones to match my application. Installation was a snap, I just followed the video included on the web site. Ordering my parts from etrailer really saved me $$ over the quotes I'd received from local shops. 512671

The axle and hubs were great. A superior product and easy to install. I would definitely purchase from you again. 466760

- 20440I-EZ-60

The product itself is great, much better in quality and weight rating to what I replaced. What could have been better is if I understood the design of the axle and the distance between the mounts. An engineering drawing with dimensions would have been helpful, especially to show the exact distance between the mount centers. This could have helped me buy all the right parts up front instead of having to order another round of parts to take to the fabricator to get welded. Again, nothing wrong with the part, I just didn't understand all the details, exact measurements, and what the difference between overslung and underslung axles was before getting started on the project. I bought this axle to replace an axle on a 4x8 harbor freight trailer. However, the harbor freight trailer is metric and this axle is presumably standard, so the spacing between the mounts is off by just a little bit in relation to the trailer's springs, about an inch. Luckily, compatible brackets can be purchased from etrailer and welded on by your friendly local welder for a nominal fee. Also, it is worth noting that this axle was meant to be mounted above the leaf springs and has the original brackets on the bottom. The brackets I needed to add were added to the top, so I did not have to remove the old brackets. Long story short, this is a great axle (much better than standard harbor freight axle), but needed to be modified slightly to fit this SAE axle to a metric trailer. So just make sure that's in your budget before buying the axle for your project. 452545


Still loving the axle. Its definitely of better quality than what I had before. The only hiccup was as I mentioned in the review, I needed to modify it with additional brackets being welded on, so all in all, not too bad.

Arrived quickly and had everything I ordered. was disappointed to find the grease on the axle when unwrapped was very dirty and old. It was a pain in the neck to clean off before installing the hubs as much of it had hardened. 208866

- 20440I-EZ-60

Product came in two separate shipment, both were prompt, one had a tear in the packaging but the piece that was meant to be there was with the package, so all appears to be intact, will know for sure when we put together on the trailer in another 2 weeks as we have been gone for that length of time. Assuming all is order, should have a good fit. The free shipping for Superbowl was a nice bonus 175353

  • In order to find the correct axle, you will need to know the dimensions from hub face to hub face and spring center to spring center, like in the photo I've added. I've also attached a link to our page with each of our available axles so you can find the correct fit.

  • Recommended Replacement Axle For Homemade Trailer
  • My recommendation is to replace the entire axle. That way you would not have any issues with replacement hubs, bearings, races, and other components you need for your trailer. I have attached a link to our product page for the axles we offer with idler hubs. You would need to measure your trailer to find the correct size axle. If you find you can use a 60 inch axle measured hub face to hub face I recommend part # 20440I-EZ-60. This includes the idler hubs with bearings, races, and seals....

  • Thickness of Trailer Axle # 20440I-EZ-60 Including Spring Seat
  • The overall thickness of the trailer axle part # 20440I-EZ-60 including the spring seat is 2-1/4 inches. The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches from the axle to the frame. Typical trailer leaf spring deflection is 1-1/2 inches.

  • Axle Availability for a Small Jon Boat Trailer
  • The closest axle we have to what you need is the part # 20440I-EZ-60 which has very similar specs as what you need, but the spring center is off by one inch as it is 48 inches on this axle. The overall capacity is 2,200 lbs and the hub face to hub face dimension is 60 inches. The spring center and hub fact to hub face dimensions are the two most important dimensions to consider when buying an axle. If you can get by with 48 inch spring centers this would work well, otherwise you would...

  • Spare Parts for Harbor Freight HaulMaster Utility Trailer 90154
  • We often hear of weak customer support and limited spare parts availability with "bargain" trailer manufacturers. I found an online copy of the owner's manual for the Harbor Freight Haulmaster utility trailer model 90154 but it includes no information at all about the bearing or seal part numbers it uses. Often these foreign-made trailers use odd bearings that are not commonly available. If you can, pull a hub and find the part numbers on your bearings and seal. Please refer to the linked...

  • Trailer Axle Rated for at Least 1,500lbs and 48" from Spring Seat Center to Spring Seat Center
  • We have a couple of axles that may work for you, # 20440I-ST-60 or # 20440I-EZ-60. These axles are 60 inches long, hub face to hub face, and 48 inches spring center to spring center. You will want to double check the spring seat measurement and if it is actually closer to 48 inches then either of these axles will work. Otherwise the spring seats would have to be removed and welded back on at the proper spacing by a qualified professional welder. Both axles come with idler hubs with a...

  • Comparing Timbren Axle-Less Suspension Systems to Standard Beam Axles for Off-Road Trailer
  • The 2000-lb-rated Timbren axle-less system # A20RS545 will be fine for your application. Since your trailer will weigh below this 2000-lb maximum there will be no real benefit from moving to a higher-rated system. That might even produce rougher handling when the trailer is unloaded. One of the additional benefits of a Timbren axle-less system is ground clearance. There is no axle beam under the trailer and no leaf springs so you can achieve better ground clearance under the trailer....

  • Will Replacing Axle Increase Weight Capacity of Trailer
  • While the axle is typically the most important factor in determining the weight capacity of a trailer, there are other components, such as the suspension system, wheels/hubs and the trailer frame itself that determine its overall capacity. An important rule to remember is that a trailer is always going to be limited by its weakest component. For example, if you decide to install the Dexter Trailer Idler Axle # 20440I-EZ-60 referenced in your question, which has a capacity of 2,200 pounds,...

  • How to Grease an Axle with EZ Lube Spindles
  • There is no outer seal with the hubs of the Dexter Trailer Idler Axle w/ Idler Hubs # 20440I-EZ-60. Just an inner seal. Permatex is not required or recommended so I would not worry about that. Here's how to grease everything upon initial installation. First, grease your bearings and spindle by hand or with a bearing packer like part # L70025. If you are going to do it by hand, start with a gob of grease in your palm and then press the bearing into the grease with some force. Next,...

  • Picking Out Replacement Trailer Hub for NU-WAY Trailer 13600/13601
  • I was not able to find any info on the axle and bearing part numbers you mentioned but I can help you determine what hub you'd need. First thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial or digital caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where the bearings ride. If you get back to me with that information...

  • What Is Needed To Replace An Old Axle With A New Axle
  • The Dexter Trailer Idler Axle Kit, Item # 20440I-EZ-60, includes most of what you need to complete the axle change and installation. It has a 2,200-lbs weight capacity and is fairly easy install (see attached video). I also encourage you to double-check your measurements to make sure you are getting the right kit for you and your trailer. This Dexter kit will include a straight trailer axle that measures 60 inches from hub face to hub face and 48 inches from spring center to spring...

  • Adapting Axle so Spring Seats are On Top Of Axle Tube
  • A 2,200 lb axle like the one you mentioned could easily be converted for a top mounted leaf spring. All you'd need to do is weld on a new spring seat # TRSS175 on top of the axle tube directly opposite of the existing ones. Simply flipping the axle over so the existing seats are on the top won't work, as the bow in the axle would have the camber of the wheels wrong if you did it that way.

  • Replacement Idler Hub Assemblies And Wheels For Boat Trailer
  • My thoughts are you have a really badly marred spindle, but that many flats is still crazy. You are most likely overloading your axle with the weights you gave. The cuts into your spindle are not good and could be from a bearing seized up that could cause issues for sure including a blown tire. If you want to swap out the hub, as long as your inner diameter on your bearings is 1 inch, the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 # AKIHUB-440-2-1K will work very well....
