The best way to determine the correct replacement hub assemblies for your trailer is to retrieve the bearing numbers stamped into the metal of both the inner and outer bearings. With those numbers, we can find which hubs would be a correct fit. I am including a link to a video that will show you how to remove, inspect, and reinstall trailer bearings, races, and seals.

I have the Dexter Trailer Hub Assembly, part # 8-91-05UC1 which has a 4 on 4 bolt pattern. It uses the TruRyde Bearing, part # L44649 as an inner and outer bearing. This bearing has an inner diameter of 1.063 inches. 1-1/16 inches will translate to 1.062 inches. This hub is designed for Dexter 2,000-lb axles.

I went out to the warehouse and measured the hub journal length of the hub, which is the measurement from the back edge of the center hub casting to the front edge of the center hub casting and it measures 4-1/4 inches long.

I would also recommend to make sure and use the same size hubs on the same axle.
