Expert Reply:

To find the right replacement hub for a trailer you will need the inner and outer bearing numbers stamped into the sides of the bearings or the measurements of the spindle to 3 decimal places. The measurements have to be as accurate as possible so I recommend using digital calipers # PTW80157. I included a picture that shows where to measure.

If the spindle diameter is 1 inch the whole length where the bearings ride then hub # AKIHUB-545-35-K will not fit. It takes 2 different bearing sizes with different diameters. There is a bearing that has exactly a 1 inch inner diameter, L44643.

If these are the bearings you have or the spindle is straight with a 1 inch diameter and you need the 5 on 4-1/2 bolt pattern then we have some options. Hub # AKIHUB-545-2-1K is designed for 8 to 12 inch wheels and # AKIHUB-545-2-LF-1K is for 13 to 15 inch wheels. I have linked videos of both hubs.
