What Chucky said. Still wondering on what you figured out.

 

What's the outcome psychosurfer?

 

He hasn’t been on the HAMB since 2017.

 

This is an old thread (with OP typically failing to post the resolution); but a good reminder to follow one of the first steps in practically any disc brake brake kits; the one that says: "replace the inner bearing race (cup) in the rotor with the one provided in the kit".

They sent the "extra" parts for a reason; don't throw them away. I actually had to have a buddy dig his new inner races out of a dumpster.

 

If you two don't mind you are both correct. If you buy one it's going to say cup on the box. Timken call them cups & cones. There are indeed places the cup running surface is called the race. To make it even more confusing, there are terms inner ring and outer ring. A cone would have an inner ring, a cage, & rollers. The running surface could be referred to as the inner race.

I'll give you one guess who my employer is.
