Todd,

I assume that you are asking about the one-way bearing ?

If you are, These a called roller clutch bearings( one way bearing ) and I replaced mine with one from a bearing parts house here in Pocatello.

The brand name was ' Torrington '
Part number...... RCB-061014

I used torch heat to get the bearing out and epoxy to secure the new one in. There is a snap ring on the back of the socket probe that comes off ---piece of cake......

hope this helps
