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.


Dexters

Dexters 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"

Very fast delivery for a axle and hubs. Spring center for my trailer was a 47 and all places only had 48’s. Welded the spring mounts a 1” shorter and all was great. Very good quality axle it will work great. Sorry no pictures of my project, time crunch.

After years of hauling firewood my Harbor Freight Trailer Axle fatigued and cracked. The Dexter Axle from etrailer got me back on the trail. Welded leaf spring seats on the opposite side of the axle at a spacing of 46.5 inches. The wheels stick out an additional 3/4 inch per side. The trailer now rides like a Cadillac. Very excited about putting my faithful trailer back in service, with a serious axle underneath that I have confidence in. The folks at etrailer very helpful and responsive. Thanks



by:

Everything was as expected and we were able to repair our trailer without issues. Shipping was prompt and the service was great. Received the package one day earlier than initially promised



by:

I purchased a number of products from etrailer and I am very pleased with them all. The shipper lost my axle. When I contacted etrailer customer service, they handled my problem quickly and I had a replacement axle in a couple days. Well done!

The products were all of high quality and the assemble was much easier as a result. I have attached a few pictures of the build for those interested.

Thanks etrailer for your great products and service!!



by:

These axles work great. I replaced three axles on my trailer last fall (2022) with these axles. I was able to install the new axles and springs in about 3 hours because everything matched up very nicely - thanks to the help of the folks at etrailer.



by:

Had all parts necessary to add a new axle to my trailer.Parts are well made and easy to install.



by:

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.



by:

Quick delivery with tracking link! Great product and price!! Easy process to install axle and hubs. I would have appreciated a torque specification for the U-Bolts and Lug nuts in the video. I didn't take the time to search other locations or Q&A.

Tip: 1-1/2 " PVC makes a great tool to seat the grease seals. I used my 28MM socket, it was very close to size. I decided to use 2" Schedule 40 PVC pipe to install the E-Z Lube dust seal. I have many tools however no wooden hammers.

Product seems to be built well. I was missing a set of outer bearings that I had to get from a local tractor supply due to time constraints. They were missing when shipped to me. I have been happy so far with this product as I have pulled my home built teaardrop on it. I have traveled over 3k miles with it as well as a tire set I purchased from etrailer.
Contender ST205/75R15 Radial Tire w 15"
Good sturdy wheels and tires and they look good in person.



by:

Really good solid axle... I needed the mounting tabs moved and had a metal fabricator do the work for $20.00. This was used on an old boat trailer that I turned into a utility trailer. Also swapped out the springs with ones purchased from etrailer too. To complete the package I ordered (3) 165/65-8 trailer tires. The trailer tows straight and hauls everything I've ever needed to.



by:

So far the hubs haven’t been delivered but I got the axel early which was nice - just waiting now for the rest but I imagine all will be well when they arrive - the only reason for the 4 stars is the separated delivery of the axel and hub.



by:

I installed the Dexter axle on my trailer yesterday, and I was very impressed with the quality and the ease of installation. The install took much less time than expected, and this was helped by the hubs having the bearing pre-installed, what a bonus! This is a great solution to replace a fried axle, I highly recommend it.



by:

This axle kit made it fairly easy to rebuild my trailer. The pictures show what I started out with for a trailer and what the finished trailer looks like.



by:

Fits as it should. EZ lube hubs are much easier than having to repack the bearings. This is the second purchase I’ve made from etrailer and their service has been great.



by:

I bought a axle, springs wheels, hubs etc. to build a utility trailer, I inadvertently had ordered incompatible hubs for the selected axle the person filling the order noticed this and contacted customer service to alert them of the issue who then called me to correct the problem. This saved me the time and expense of returning the part and delaying the project. great service, attentive, knowledgeable employees and great products.
Thanks E trailer.



by:

Solid axle with all the bolts and brackets to mount the axle quick and easy. Solid axle, should last a long time.

I recently purchased a 1997 Pacific boat trailer, 2,000 lb capacity. Installed new lights, spare tire carrier, and tongue jack two months ago. Decided I may as well replace the wheel bearings and seals only to discover the spindles had deep gouges from the seals or material between the seal and spindle shaft. The right side (as viewed from the rear) even had a deep gouge in the seal area from who knows what. Surprisingly, the wheel bearings were fine.

My initial intention was to use what is called a "speed sleeve" to repair the seal contact area on the spindle, in addition to replacing the wheel bearings. The bearings were an odd size, thus somewhat expensive. Cheaper to replace the hubs but with the "speed sleeves", would come out to nearly $200, notwithstanding my labor.

To the rescue, etrailer! I measured my existing axle per the directions from the staff and ordered a replacement axle with hubs and a U-bolt kit for nearly the same price. Shipping was surprisingly fast given current events and a brand new axle and associated parts were delivered last night (8 April, 2020).

I've replaced wheel bearings before but have never replaced a trailer axle, so I was initially somewhat intimidated by the job. I jacked the trailer up to remove the wheels and used jack stands to ensure it would remain that way while I proceeded to remove the old axle.

The u-bolts (not quite a U given the square axle) were not too bad to remove. I used copious amounts of WD-40 on the threads and an adjustable wrench did the rest of the work. I was going to use an air ratchet but did not have enough clearance and did not wish to risk raising the trailer any further.

The old axle came out fine and was a bit heavy, around 50 lbs by my reckoning. Given the service life of 23 years, I'd say it did a good job (it was the original axle). Interestingly, the new axle weighed a good 10 - 15 lbs lighter...

The new axle went in fine, although due to the camber, which the original axle did not have, it took a bit of "squeezing" to get the holes on the spring seats. Nothing terrible, and my initial measurements were correct.

I did not take photos of the bearing and seal installation process as my hands had a fair amount of grease on them but if you follow the instructions, it is relatively simple. Make sure you "cup" the outer bearing area with grease in your palm to force it between the rollers. You will know when you have enough as it will be pushed between the rollers on the other side. Take a look at some [online] videos if you have never seen it done before. I believe there is a video on the etrailer website.

I used a short piece of 2x4 to install the seals and they went in without fanfare. I would recommend wiping a thin film of grease on the seal seating area of the hub prior to seal installation.

Installing the hubs was relatively straight forward, I seated the bearings while rotating the hubs to the recommended 50 ft/lbs. Then backed off WITHOUT rotating the hub, finger tightening, and installing the locking clips, which I have never seen before as I typically use cotter pins.

I installed the wheels and will be installing my "Bearing Buddies" later this afternoon.

All told, the job took me approximately 2 1/2 hours, maybe 3. I took my time and did my best to ensure it was a safe evolution given that the trailer had to be raised enough to allow axle replacement.

I will re-torque the u-bolts after some use and will probably re-seat the bearings as well. The price on the new bearings and seals is a significant improvement over what had come standard with the trailer.

Tools used were a 3/4" socket and 3/8" drive ratchet, 10" adjustable wrench, 1 1/2" socket and 1/2" drive torque wrench, 1/2" socket for the new u-bolts, a soft faced hammer to remove the "Bearing Buddies", (2) jack stands, and standard floor jack. Paper towels were most helpful during the bearing greasing and installation process...

If you have never done this before, like me, I can assure you it was relatively straight forward and I'm sitting here somewhat proud of myself...

Kudo's to the staff at etrailer!

A great product for the price installed easy and I bought 3 for a tri axle and couldn't be happier I made a 20 foot trailer to haul 4 wheelers and snowmobiles



by:

This trailer has been perfect. Love not having to shovel gravel, etc. So much easier. Thank you again.
Your service was exceptional. Thank you for reaching out.



by:

Used it on a homebuilt trailer worked great and tracks perfectly.



by:

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.



by:

Everyone at Etrailer are awesome to work with. Thank you all.



by:

Product was top notch and customer service was even better. Was missing a bolt from package; it was overnight shipped at no cost to me. Will always do business from etrailer



by:

Great company. Never a problem with orders. Fast shipping. My first stop when I need something.

  • Replacing an Axle on a Narrow Trailer
    With the measurements you provided, unfortunately we will not have a through axle available for your trailer. However, we do have a Timbren Axle-Less System that may suite your needs. The # ASR2KHDS01 will not require spring seats and as long as the hub face measures 6 inches to the frame, it would be a great option. This does not come with hubs, though, so you would also need to get two of the Dexter Idler Hubs # 84545UC1-EZ.

  • Can You Move the Spring Seats on the 2K 60" Dexter Trailer Axle with Idler Hubs
    Correct, you can move the spring seats on the Dexter Trailer Axle with Idler Hubs part # 20545I-ST-60-10 in or out to match your trailer. In order to do so, simply cut the tack welds to free the seat and then tack them back into place where you need them. Please note, you'll also need new u-bolts like the U-Bolt Kit for Mounting 2K Axles part # APUBR-10. If you damage the old spring seats cutting them off you can replace them with the Spring Seat part # TRSS175.

    Mobile home axles like what you have on your utility trailer are designed for one time use and really should not be used on a utility trailer. Your best bet is to replace the axle with one built for a RV/Trailer. You will need to measure the hub face to hub face measurement of your current axle, the spring center to spring center measurement, and the weight capacity of the axle.
