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 replaced the old axles on my trailer. I found these to be excellent quality. The install was not bad. I've taken a couple of long trips maybe 1000 miles one way and loaded. These axles head up perfectly.

I am sorry to see that you are unhappy with the axle and I am happy to help in any way that I can.

Great service, always on time and priced right

Exactly what I ordered packaged nice and pregreased bearings.



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:

Aside from not received complete order the first time, I will still recommend etrailer for all your needs



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:

The axle seems good. Nice that the ball bearings were grease. We will see over the miles if all goes well. The delivery, besides the break assembly was quick. Not sure why the break assembly was not shipped with the rest.



by:

Best thing I did was change axles to these. Went from 3500lb to these 7000lb with brakes on both. Tows and stops incredible.



by:

I wish I could give negative stars. My order arrived on time, but it was the wrong axle. The axle I ordered and paid for was a 3500 lb drop axle with electric brakes, they sent a bare 3500 lb drop axle. $[XX] difference. I immediately contacted customer service who required pictures of what I received. When I supplied them, they did not respond and even removed my order from their website so I can't track it to see if they're trying to make this right. They won't answer emails either because Ive sent a few. I'll try to get my credit card to refund me since they won't respond.



by:

Piece of cake to install. Pull out the old snapped axle install new axle. Bearings come pregreased.



by:

I was worried about ordering trailer parts from a new company online. Product showed up fast and on time. Beat most other product pricing. A courtesy email was sent when product was delivered, making sure I was satisfied, giving me a direct contact incase I had any issues.
I haven't used the product yet but everything looks good.
Will order trailer product again in the future.



by:

Wrong axle sent did not need the 4" drop down.



by:

Super fast shipping, excellent packing to protect the product. I have not opened all the boxes yet but plan to work on the install in the morning.



by:

The guys and gals at etrailer are the b est!



by:

Great product and customer service. Perfect replacement for my damaged axle. Would purchase from again.



by:

Not only is it not what I ordered 2 of the TA cayman parts and pieces in the advertisement. It doesn't say anything about coming in parts and pieces. I'm not a mechanic. Now I have to pay somebody to put it together. I think that's very poor business



by:

Paige was a huge help in getting me what I needed and fast!
Got my new axle in a day and was back on the road.
You will not be disappointed with etrailer!



by:

Product was exactly what I was after and helps me too get trailer back to work faster.



by:

Where the leaf spring sits on the axle was off about 1/4 inch had to finagle the axle abit but made it work.



by:

It's been a year since install and all is well! Thank you!

  • Can Axle Weight Rating be Increased with Upgraded Leaf Springs and Hubs
    To upgrade your axles to a 5,200 lb weight rating you'll have to swap out your 3,500 lb axles for 5,200 lb axles like part # e55SR that comes with electric brakes and has 95" hub-face and 80" spring-center measurements. Unfortunately you have to upgrade everything to get the higher weight rating as the axle tube itself will need to be stronger. And even after you upgrade the axles it doesn't necessarily mean your trailer can handle more as the trailer frame is also a factor when it comes...

  • What is Needed to Upgrade From 3,500 lb to 5,200 lb Axle
    From what I can see your Keystone trailer has a pair of 3,500 lb axles so to upgrade to 5,200 lb axles you'd need the axles, U-bolts, and hubs. In order 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; I have added a link below to a video which walks you through how to measure. For example, the 5,200 lb Trailer Axle w/ Electric Brakes # e55SR measures 95 inches from...

  • Is There a Replacement Spindle For a Dexter D44, 4400LB Trailer Axle?
    My recommendation is to replace your axle with a 5,200lb like # e55SR as the 4,400lb spindle is so uncommon they are not readily available. This will give you stronger components to lessen the chance of you having to replace a spindle in the future. If you can provide me with the dimensions for your axle I can verify the correct replacement for your D44 axle. The #84 E-Z Lube Spindle # TRU74FR while similar has a narrower diameter of 1-1/16" for the outer bearing where a 4,400lb uses...

  • How To Upgrade Hudson 10,000LB Trailer From Mobile Home Wheels & Tires To Standard Wheels & Tires
    To switch your 10,000lb Hudson trailer to use more standard wheels and tires you will need to replace your axles. The spindle size used on your current axles is only going to allow for the Mobile Home style wheels and tires since the hub is specific to these axles. You will need to measure your axle from hub face to hub face to determine the correct width axle you will need. Here is a list of 5,200lb axle which include electric brakes and have a 6 on 5-1/2" bolt pattern. If these do not...

  • Replacement Axle Options For Obsolete Trailer Axle Using Dexter 22834 Hub and Bearings 2788 and 1779
    I recommend replacing your axles as the 22834 hub is obsolete and you will want to upgrade to more commonly found parts. 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.

    We do have a selection of axles that use an 80" spring center and a 95" hub face that should meet your needs. You'll just need to choose the correct one based off of weight capacity: - 3,500 lbs # 7359765-EB - 5,200 lbs # e55SR - 6,000 lbs # 7461121-EB - 7,000 lbs # 8327834-EB Attached is a link to our selection as well as a video on axles for you to check out.

    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.

  • Replacement Axle and Brakes for 87 Inch Long 3,500 Pound Axle on Travel Trailer
    Thank you for providing that information. Although we do not have an 87" axle available, you can use the Trailer Axle Beam with Easy Grease Spindles - 89" Long - 3,500 lbs # e38GR. Since this axle is 89" long it will stick out an extra inch on either side of the travel trailer. Also, the spring center is 74" so you will need to cut off the spring seats and weld on # TRSS238 to match your 68-1/2" measurement. For brakes I recommend the Electric Trailer Brake Kit # AKEBRK-35-SA. These self-adjusting...

  • Bearing Kit For Lippert 5,200LB Axle Tag Number 121067
    Your 5,200LB Lippert axle 121067 will use the Bearing Kit # BK3-300. This will give you the bearings, races, grease seal, and cotter pin for one axle hub. The Seal Puller # PTW1219 and Installation Set # PTW83020 will aid you in the removal and installation of the parts. I recommend using the LubriMatic LMX Industrial Strength Grease # L11390 with your bearings as it works great in both hot and cold climates.

  • Replacement Axle, Hubs, Brakes, and Tires for Older Trailer With Dexter 22834 Hub
    Based on the axle and bearing measurements it looks like your trailer was using a Dexter 22834 hub. The Outer Bearing # 1779 has an ID of .938" and the Inner Bearing # 2788 has an ID of 1.50". The outer bearing is slightly off but that may be due to a measuring error. That would also mean you have 5,200 lb axles on the trailer. This is an obsolete assembly so you will need to replace the entire axle. For a replacement you can use the # e55SR. This will stick out an extra 3/4" on either...
