What is the name/manufacture of the sin bearing?

[epapp]

The reason for the dual row focus is because my car has a dual row

The solution to assessing the health of the bearing is so damn simple, and I can't believe I just thought of how to do it yesterday. Needless to say, after I brought it up to my PI (the phd engine guy), he too immediately said there is such a simple solution, and its the same idea I had. It requires math and stuff, but hey, thats why I'm in graduate school.

If you had that paper that would be most excellent. I could solve my problem if I could just pull my bearing out. (anybody got an old bearing to send to me?)
