If you could not find the bearing numbers when you took apart your hub assembly, you are going to need to know the inner diameter of your spindle where the grease seal and bearings ride in order to get the correct replacements.

Use a digital caliper to measure your spindle to the thousandths of an inch where the seal bearings ride. You can use the photo I've attached to see exactly where you need to measure.

I've also added a link to a help article on common bearing sizes, as well as a link to our available bearing kits.
