In order to find the correct wheel bearings, you can take apart your hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you would need to use a digital caliper such as # PTW80157 and measure your spindle to the thousandths of an inch where the 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.
