Review of Dexter Trailer Axles 35545E-ST-89


Today we're going to review part number 35545E-ST-89. This is the Dexter Trailer Axle with the standard spindles, has the electric brakes, has the hubs of the 5 on 4 1/2 inch bolt pattern. The axle is 89 inches long and it has a 3,500 pound weight capacity. This part will include everything showing here on the table with the axle, the two hub in drums, the two brake assemblies both right and left, includes the inner and the outer bearings. Now the bearing races are included, they are already pre-installed into the hubs, has the grease seals included, the dust caps, the 1/2 inch lug nuts, comes with the mounting hardware to attach the brake assembly to the flange on the axle and it comes with a can of the marine gray wheel bearing grease. Now this axle beam right here will act as part of your trailer suspension system. This could be used to replace an axle on your trailer or you can use it to fabricate the suspension to fit your specific application.

It's made of a high strain steel construction. If you notice here there's a underslung design and by that, that means the spring seats are welded to the underside of the axle. This is where your mount release springs too, so this will give you a nice low ride high which makes it easier to load and unload your trailer. This axle does have the straight spindles, there's no drop to it. It is a standard grease application. This does ship with the included castle nut, the washer and the cotter pin.

Now, when we do ship it, we don't ship it just bare like that, basically, what they do as the machine surfaces they will put grease over to protect it and they'll wrap it with bubble wrap and use a very heavy-duty thick corrugated tube that would mount over it and then be wrapped around it. That will prevent any damage from shipping. Now the spring seats and the spindles are all welded onto the axle. On the axle itself, you might notice it's hard to see in this video but the very middle right here will actually raise up, has a nice bend to it. Basically, the reason that's in there is it creates a zero camber angle for even road-to-thread contact across the wheels of your trailer tires. This one ensure that angle of the wheels is correct for your towing needs, basically what happens is because it's raised in the center, then when your trailer is loaded up and loaded down that weight would push down on that axle which would even straighten that axle out and give your thread on your tires even where all the way across.

That's helps with the straight line acceleration and it gives you a steady controlled towing. Now the electric brakes here are easier to install than any drum brakes. There's no actuator or hydraulic lines necessary. A mounting hardware is all included, to mount these assemblies to the flange on the axle. A cast iron hubs right over here and the drums are sturdy and durable. The dimensions on the drum is 10 inches in diameter, 2 1/4 inches wide.

The bolt pattern is a 5 on 4 1/2 inch bolt pattern and the studs to use a wheel lug size of a 1/2 inch by 20. You can use this with wheel sizes anywhere from 13 inches to 17 1/2 inches. The weight capacity on this is 3,500 pound. The outer diameter on the tubing of the axle is 2 3/8 inches. The spindle diameter is 1 1/16 inches. Again, here's the brake flange configuration. You can see it's the 4-bolt design and also on each end, there's a loop here and a loop down there. This wiring runs through the axle, this is what you would use to connect to your wiring on your trailer to wire up your electric brakes too. Basically, on the axle there's multiple ways to measure the length of the axle beam, but the two most accurate ways are going to be the hub face to hub face and the spring center to spring center length. I'll show you both of those lines. The hub face to hub face length is actually measured from the base of one wheel stud, so another words, that would be measured. You have to have your hubs on your axles to get the correct measurement but you measure from the base of one wheel stud across the axle to the base of the wheel stud on the opposite hub on the opposite side. If you had these hubs installed on this axle, just give you an idea here, the hub face to hub face length to be roughly right at 89 inches. Now the other measurement would be the spring center to spring center length, this actually will give you the approximate width of your trailer and it's measured from the center of the spring seat here to the center of the spring seat on the other side. On this one, we can measure easily because they're already mounted on there. You can see this would be right at 74 inches. Basically, if you're replacing your trailer's axle you should be able to determine which type you need by the trailer's capacity, the bolt of the wheels that are on it, the brake type and then those two lengths, the hub face and spring center lengths. That should do it for the review on part number 35545E-St-89. The Dexter Trailer Axle with the Standard Spindles and the Electric Brakes with the 5 on 4 1/2 inch bolt pattern and a 3,500 pound weight capacity. .
