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.


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.


Note: Axle does not come fully assembled.


Pre-Greased Hubs

A trailer hub with the grease cap taken off shows greased bearings

The pre-greased hubs in this kit come with the bearings, races, and seals already installed, which makes for a faster install time and less mess to deal with. After you've put on the grease caps and lug nuts (included), you'll be ready to roll.


etrailer Axles

etrailer 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.


Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI Laboratories for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.


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"

I ordered two axles to upgrade my trailer capacity to what the frame is rated for, 12,000lbs. The axles have great bearing seats and backing plate studs. The backing plates are fully assembled and ready to connect to the wires already installed into the axle tubes. The hub assembly went smooth and only one set of break shoes needed adjustment. A good buy along with the 5 fully assembled tires and wheels.



by:

Arrived on time and in good condition. The ends of the axel should be better protected. The delivery person dropped mine vertically on the asphalt. Fortunately, the crown nut took the blunt of the impact and the grease fitting wasn’t damaged.



by:

I used these axles to upgrade my travel trailer suspension.they Seem to be a good quality item. Good paint job on the axles. Compared to axles that came with the travel trailer. Which helps living on the coast.



by:

Great videos that walked me through the installation being I’ve never done something like this before!
The fit was prefect for my trailer.
The only issue was the grease zerts were galled in shipping & I had to replace both zerts.
My recommendation would be for etrailer’s shipper to provide better protection for the axle zerts.



by:

Great axle so far has handled everything I have put on it so far and that's been a lot. Bought this because I managed to bent the axle by hauling my wife's equinox on it and hit a pot hole the size of grand canyon that bent the axle beyond safe operation. The other axle didn't get bent nearly as bad as this one but will also be replaced in the next year or so. But so far this replacement brake axle has held up pretty well over the last year.



by:

The brakes came apart in shipping and there should be directions on how to put it together



by:

Great product, as described, staff was vary helpful in making the purchase easy.



by:

Part arrived early, great communication from the team at Etrailer through the proccess.



by:

etrailer is the best. I've been dealing with them for years. The orders are always right. The products are top-of-the-line.
Delivery was fast and free.. I have ordered online and I have called and spoken to the sales staff there who were very helpful and knowledgeable about their products. If you have trailers and you don't give a trailer look, you are missing out.



by:

Great value. I upgraded a 3500lb trailer and with the added brake it really helps. I use it to haul tools around so it handles the weight much better. Towing is a breeze now. Installation was easy as well. I will be buying more axles and parts in the future.



by:

The axles are not yet installed. There was 1 bolt missing I called and they shipped it out immediately. to date everything was as they said. My delivery arrived much sooner than excepted. I would recommend using etrailer they have a very good process.



by:

The replacement axle is working very nicely. It is well engineered and quality’s is evident



by:

Everything was going great on my new axle install today, until it wasn't. You shiped me the wrong lock washers for the brake backing plate. The correct nuts but the washers are to small. I'll have to pick them up because the customer is expecting the with to be done be today.



by:

Exactly what I ordered packaged nice and pregreased bearings.

  • Looking For 3,500 lb Trailer Axle To Replace Lippert V000112723
    Hello Kirk, I do appreciate you reaching out, but I will tell you up front that we do not offer a direct replacement for your axle. We offer only two sizes of 3,500 lb axle and ours are 89" hub face or 95" hub face, so much too long for your application. For a direct replacement I suggest reaching out to an axle manufacturer like Dexter. They have way more axle sizes than we do, and they may even be able to custom make something for you.

    The Outer Bearing # 1779 and Inner Bearing # 2788 are going to be specific to your current 22834 hub. You will need to replace your axle as the current 5,200LB axles use a much larger spindle.

  • Availability of 5,200 lb Axle With Idler Hubs
    Although we do not have a version of the # e75SR that comes with idler hubs, we do have the parts needed to put this together. All you need is the # e55GR along with the Easy Grease Trailer Idler Hub # AKIHUB-655-6-EZ-K. This is pre-greased so it is ready to go. The hubs have a slightly higher capacity at 6k but they use the same bearings and grease seal so it won't hurt anything. You will still be limited by the 5,200 lb capacity of the axle.

  • Can Trailer Axle with Electric Brakes 89" Long - 5,200 lbs Be Ordered with Overslung Spring Seats
    The Trailer Axle with Electric Brakes part # e75SR doesn't come setup for overslung applications. That said, all you would need for this is the Dexter Trailer Springs Over-Under Conversion Kit part # K71-385-00. The axle has a slight bow to it which is by design so you wouldn't want to rotate it either.

You're just going to need to measure your hub-face to hub-face and your spring-center to spring-center. This particular axle has an 89" hub face measurement and a 74" spring center measurement so if that's what you have then this axle will work great. If not, come back with those measurements and we'll find something for you. You're also going to need new u-bolts. I recommend going...

    With you having mobile home axles only designed for one time use you would have to cut off your brake assemblies since the backing plate is welded to the axle. Then you will be able to weld on a Brake Flange # 4-44-1 to each of your hubs. This will allow you to bolt on the Brake Kit # AKEBRK-6 for each of your axles. Then you will be able to get Replacement Shoes # AKBRKR-S-12 in the future. Depending on the condition of your axle you may be better off replacing the entire axle. If this...

  • What is Most Common Leaf Spring Length for 3,500 and 5,200 lb Trailer Axles
    If you are picking out springs for a fabbed up trailer I would go with the more common leaf spring lengths as that will make picking out replacements in future a little easier. For 3,500 lb axles the most common length would be 25-1/8 inches like the # e68SR. In the 5,200 to 6k range the 25-1/4 inch length is the most common like the part # e34SR.

  • Replacing 3,500LB Trailer Axles With 6,000LB Axles On 42" Wheelbase Travel Trailer
    On an axle like the Dexter Trailer Axle w/ Electric Brakes # 35545E-ST-89 the maximum overall overhang(hub face to spring center distance) is 18" total. That will put your current axle 2" past the maximum with having an 89" hub face and 69" spring center. A 5,200lb Axle # e75SR will only allow for a 19" overall overhang, so you will need to move to a 6,000lb Axle # e65SR as it allows for a 20" overall overhang. This will require you to move to the 6 lug wheels. With the MORryde 14-3/4"...

The Outer Bearing # 1779 and Inner Bearing # 2788 are going to be specific to your current 22834 hub and there is not a replacement that uses that same spindle size.
