Review of Dexter Trailer Axles 35545E-ST-EZ-89

Today we're going to review Part #35545E-ST-EZ-89. This is the Dexter Trailer Axle with the straight EZ-Lube spindles, the electric brakes and the 5 on 4 and a 1/2 inch hub and drums. The axle itself is 89 inches long and has a 3500 pound weight capacity. This axle beam will act as part of your trailers suspension system. You can use this to replace an axle on your trailer or to fabricate a suspension to fit your application. It comes with the spindle nut, the D-ring washer and the nut retainer. It's made of a high strength steel construction. It does have the straight EZ-Lube spindles, there's no drop to it.

On an EZ-Lube spindle, it does have the built-in grease Zerk fitting on the very end. That's where you would lubricate your bearings so you don't have to remove the whole hub and drum. You can just lube it from right there. This part number does include everything shown here. It includes the electric brake assemblies, both the left side and the right side. It includes the hub and drums and the mounting hardware which are these washers and these nuts.

That is used to hold the brake assemblies to these mounting flanges. It also will include the bearings, the outer bearings, the inner bearings, the races will be included and they are actually pre-installed in the hub and drums. You can see right there, they're already installed. It will come with the grease seals. It comes with the EZ-Lube grease caps. The EZ-Lube grease caps, again, the reason they're EZ-Lube, it's nice, they have a rubber plug that you can pop out to access that Zerk fitting on an EZ-Lube spindle.

It will come with the ten 1/2 inch lug nuts. Also we include a 2 by 14 ounce tube of marine grade bearing grease that you would need to install with just a grease gun that would hold 14 ounce tubes. If you have one at home, you can use that, if you don't, we also sell that separately. We offer this one, it's a related part on the product page. It's Part #L30200, a grease gun. Basically on the axle itself, all axles will have a bend in the middle. They actually will bend upwards.

This will create a zero camber angle for even road to tread contact across the width of your trailers tires. Having the center riding a bit higher and the sides are lower allows this axle, when a load is put on it, it will compensate enough to give this straight across and have your tires road to tread contact all the way across the tire. This will give you excellent straight line acceleration and steady inline tracking. This axle, the spring seats which are right here, they're well lit underneath the underside of the axle. This is an underslung design and that means that they're well lit to the underside. This will give you a low ride height which makes it easier to load and unload your trailer. The spring seats and the spindles are all welded onto the axle. It also has the four bolt brake mounting flanges you can see that your electric brakes would bolt to. It also has a wiring loop there and one on that end. Basically, that's to hook up your electric brakes too. Comes with that in the axle itself. On the 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 your most accurate measurements. The hub face would be, once these assemblies are all installed on there, you would measure the hub face length. You would measure from, right here, which is the base of the wheel stud, once this is installed. From the base of the wheel stud on this side to the base of the wheel stud on the other side. After these hub assemblies are all installed, if you measured that on this axle it would give you a hub face to hub face length, since they're not on there, I'm just going to give you an idea, it's going to be right at 89 inches. That's why this is considered an 89 inch axle. The spring center to spring center would be right here where the spring mounts are. If you measured from the center of this one to the center of the one on the other end. We'll try to do that to give you an idea, center to center. It's going to be 74 inches spring center to spring center length. Basically, when you're going to replace your trailers axle, you should be able to figure out which axle you need by determining the trailers capacity, match it up to the correct axle capacity. The bolt pattern of your wheels, the brake type and then these lengths I mentioned, the hub face to hub face and spring center to spring center. Just to mention again, the weight capacity on this is 3500 pounds. The hub face to hub face length I measured was 89 inches. Spring center to spring center length was 74 inches. The hub bolt pattern on these hub and drums is 5 on 4 and a 1/2 inches. The diameter of the tubing here, the outer diameter is 2 and 3/8 inches. The spindle size diameter is 1 and 1/16 inches. The wheel stud diameter on the studs here is a 1/2 inch, that's why we include the 1/2 inch lug nuts. And this we'll use anywhere as a wheel size from 13 inches wheels all the way up to 17 and a 1/2 inch wheels. That should do it for the review on Part #35545E-ST-EZ-89, the Dexter Trailer Axle with the straight EZ-Lube spindles and the electric brakes. .

Is there a version of this with the mounting brackets on the top?

This axle is a 2-3/8 inch diameter axle and if you need to "flip the axle" it is recommended to use an over under kit like # K71-384-00 that is designed to work with this axle diameter. Unfortunately at this time we do not have a video that shows the installation of an over under kit, but I have linked you to the product page where there are additional images and information that will help you out.
