Straight trailer axle measures 89" from hub face to hub face and 74" from spring center to spring center. Includes idler hubs - with bearings, races, and seals - for 13" to 17-1/2" wheels. EZ-Lube spindles for simple lubrication.
Bearing, Race, and Seal Information
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.
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 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.
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.
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.)
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.)
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.

Today we're going to review part number 35545I-EZ-89. This is the Dexter Trailer Axle with the Idler Hubs. The bolt pattern is a 5 on 4 1/2 inch bolt pattern. It's an easy lube design and has a 3500 pound weight capacity. Now this Axle being will act as part of your trailer suspension system. It is used to replace an axle on your trailer and it's made of a high strength steel construction. Now this is a under slung design. If you can see the spring seats on each end are welded to the under side of an axle for mounting your lease springs to. The under slung design will give you a low ride height which makes it easier to load and unload your trailer. Now you might notice in the very center here, there's a bend near the center of the axle, this is what ensures the proper camber angle.
Basically each axle manufacture to create a certain camber angle. This will ensure that the angle of the wheels is correct for your towing needs. Each axle is made so that your trailer's tires will run along the pavement evenly with contact across the whoIe width of the thread. The result is an excellent straight line acceleration for steady in line tracking. Having the center of the axle a bit higher and the sides bent lower allows the axle to give just enough when you put a load on your trailer. That load would push down on that and even that out and give you the correct contact patch of your tires. Now this does include the straight easy lube spindles on each end if you can see here and it also includes the spindle knot, the D washer and the knot retainer.
There is no drop to these spindles. At the very end, this is a easy lube design, so there's an easy lube zerk fitting, it's a grease zerk fitting that you attach a grease gun to and that would lube the bearings that are installed on here. Now the spring seats right here and the spindles and these break mounting flanges are all welded on. Now this part does come with these cast iron idler hubs which are sturdy and durable. Now the idler hubs do not have breaks so you won't be using these break mounting flanges, those would be used . those in the wiring that's included here would be used if you're wanted to eventually down the road upgrade to putting electric breaks on the axle itself. This part number actually just comes with the idler hubs. Now the bearings, as you see here, the inner and outer bearings are all included.
The races are already pre-installed into the idler hubs themselves, the grease seals, the grease caps and these are the easy lube that have the rubber plug that comes up so you can access the zerk fitting, they are all included. Comes with the 10 1/2 inch log knots and this marine grade wheel bearing grease is also included. Now the capacity on this is, its weight capacity is 3500 pounds. There are some measurements on this axle with . there's multiple ways you can measure the length of an axle beam but the hub face to hub face and spring center to spring center lengths are your most accurate. Hub face would be when you put these idler hubs on and connect them all down. If you'd measure from the length of ...
measure from the base of 1 wheel stud to the base of the wheel stud on the other side, that would give you the hub face to hub face measurement and I'll do that just right now. I don't have the hubs on but just to give you an idea of the length once they would be installed. it's going to give you 89 inches, would be your hub face to hub face length. Now the other most accurate measurement would be the spring center to spring center length and that's basically right here. The approximate width of your trailer is measured from the center of 1 spring seat on 1 side to the center of the spring seat on the other side. Again if we just run center spring seat to center here, it's 74 inches. Now there's also another measurement which is the break mounting flange to the break mounting flange. Now that is not as accurate as the first 2 I mentioned to you but I'll still give it to you. It's good to use if you're replacing an axle you have on there. It's going to be 82 5/8 inches. Now on these idler hubs, these are a 5 log 4 1/2 inch bolt pattern hub. They do come with the half inch log knots that bolt them onto and they will use a wheel size anywhere from 13 inches on up to 17 1/2 inches. Now the 2 big outer diameter on this axle is 2 3/8 inches. The spindle size is 1 1/16 inches. The break flange configuration, if you go to use this down the road and want to put electric breaks on it is a 4 bolt configuration. And that should do it for the review on part number 35545I-EZ-89. The Dexter Trailer Axle with the Idler Hubs with the 5 on 4 1/2 inch bolt pattern. It's an easy lube design and a 3500 pound weigh capacity. .

The axle I ordered was successfully installed yesterday. One issue I had was with the spring seats. My spring centers are 72 1/2. Knowing that I ordered the Spring Seats TRSS238. I cut off the seats that came with the axle as I knew I had to do but when I went to install the new seats I found the cutout diameter was too large for the axle. For that reason I did not use the seats. Fortunately I did a neat job of cutting off the original seats so I welded those at the location I needed. They worked fine and fit very well. It would have been a problem if I did not get the seats off the axle as neat clean as I did. Other that that issue the axle arrived in 5 days through standard shipping and hopefully will work for years to come. 273641
God the product in two days from the order day. It came in perfect shape and ordering the additional mounting brackets was very easy. Item is sturdy and was quite easy to install, especially using the helpful instruction video link (there is one missing step in the video, though. It does not show the mounting of the bushing that fits next to the inner bearing on the hub, but it was still pretty easy to figure out). Great purchase and the whole axle swap took less than 30 minutes! 228944
I get the impression that this review is intended just for the product below, which was excellent. I want to make sure it is said that the sales rep I dealt with over the phone was excellent. When I had questions I was not able to find on the net, Mark M had the answeres, found what I needed and the complete package was delivered promptly. Even to the extent of a tube of grease which I did not expect. I highly recommend etrailer! 186867
I ordered several items for a trailer I am rebuilding. One thing i ordered was an axle with hubs. When the axle arrived there were no hubs and I was worried. But when the second box arrived there were the hubs I was expecting. Thank you etrailer.com your pics and shipping saved me over $200 on a single axle. 182546
EZ Lube axle, why didn't I have this last year? With a slight modification (weld new spring seats) 2"wider track, new hubs and springs the pontoon was back to the lake the same day. Now I never have to worry about repacking bearings again. Thanks etrailer 255642
