To replace the hubs with the correct fit, you will need to pull one of your hubs. Then you can look at the inner and outer bearing which should have a number printed on them and also there is a number printed on the seal on the back of the hub. If you let me know those numbers, I can help you from there.

If you can't find the numbers printed on the bearing faces or if they are just not legible, you can measure the spindles with a digital caliper like # PTW80157 in the bearing and seal locations to give a precise measurement. I've attached a photo to assist with these measurement locations.

With the bearing numbers or spindle measurements, I can help you get the correct hubs for your trailer.
