How to Determine Axle Weight Capacities on a Trailer  

Looks like you found the chart that Jeff D made that shows common axle capacities based on diameter: Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter -…

Square axle capacities are pretty hard to determine. Unlike round axles, they do not have set capacities based on their dimensions. But what you can do is give me some exact measurements of your spindle and we should be able to see if there is a hub…

I do have a few easier options for you to determine the weight capacity of an axle other than using the bolt pattern or the number of lug nuts. The problem with using the bolt pattern to tell the axle capacity is that an axle may have the a bolt…

After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the hub back…

Yes, 8 inch and 12 inch trailer wheels with 4 bolt holes, like parts #AM20011 and #AM20122 respectively, fit the same 4 on 4 bolt pattern. If you're asking because you're replacing hubs on your trailer then it's not quite as simple. The…

You can replace a 4.80-8 trailer tire with a 4.80-12 or a 5.30-12 trailer tire, but there are a few things to consider before making the change. First, 4.80-12 and 5.30-12 tires are going to have a larger overall diameter than a 4.80-8 tire, by about…

The Dexter Trailer Axle with Electric Brakes - 4" Drop #8327812-EB measures 89 inches hub face to hub face and about 92 inches if you are including the hub being on, or from spindle to spindle. That said, once the wheel and tire are on the…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

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…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

Even though I cannot comment specifically on the grease you used because I am not familiar with it, I can tell you the best grease for trailer bearings is a a grease with a rating of GC-LB, which just means it is made to withstand very high…
