If you do not need electric brakes on your axle, I recommend the Dexter Trailer Hub Assembly # 42865-KIT. This assembly includes the # 25580 inner bearing, the # 14125A outer bearing, and a grease seal with a 2-1/4 inch inner diameter needed for the spindle on your existing axle.

Also included with the assembly are the races, grease cap, wheel bolts, and lug nuts. The hub has a 8 on 6-1/2 wheel bolt pattern. One hub assembly is included for the part number. You would want 2 of the # 42865-KIT assemblies for your axle. I have attached a review video of this assembly for you.

If you would like a hub and drum in order to have brakes on the axle, I recommend the Dexter Axle Trailer Hub and Drum Assembly # 42866UC3. This assembly also includes the # 25580 and # 14125A bearings and 2-1/4 inch diameter grease seal, as well as the needed races, grease cap, wheel bolts, and lug nuts. This part number includes the components for one assembly. I have attached a review video for this hub and drum assembly as well.

The hub assemblies that use the size bearings you measured for are rated between 5,200 pounds - 7,000 pounds.

I do have a way to give you an idea as to what the axle capacity is for your trailer but I called Dexter Axle and they were not able to look up the number, "021362" that you provided due to its age. If you have a leaf spring axle then what…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

To find the load capacity for your axle you should look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that…

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

I have attached for you below some common torque values needed for a trailer suspension system but a lot of these will vary by bolt size and other factors. U-Bolts: Varies by Size - 1/2" bolts: 45 ft/lbs - 70 ft/lbs, 9/16" bolts: 65 ft/lbs…

Answer 11

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…

Answer 12

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
