There's a few things you need to know that will tell you which hub fit your trailer's spindles.

The first is your bolt pattern. I've attached a help article on measuring your wheel studs or wheels to find the bolt pattern. You also need to determine the weight capacity of the trailer's axles and which bearings fit the spindles.

The axle likely has a tag on it somewhere telling you the capacity. The bearings are stamped with their numbers or you can measure the spindles where the bearings ride to find their inner diameter. You need to measure as exact as possible so use a caliper, like part # PTW80157. Once you have the inner diamter of the bearings you can use that measurement to find your bearing numbers on our site. I've linked our bearing selection to help.

Once you have the information go to our selection of hubs, I've attached this link as well, and use the filters to select your bolt pattern, axle capacity, and inner and outer bearing numbers. This will leave you with the hubs that are a fit for your trailer's spindles.

If you prefer, reply back with your bolt pattern, axle capacity, and bearing numbers and I can make a specific recommendation of hubs to fit.
