I just came back from my dealer. The bearing does not show up on the parts catalog ... I already knew that. You have to purchase the entire pulley. BUT, that bearing is available from Toyota. It has another application and it takes a rather knowledgeable Toyota guy to know this. Fortunately, Dan has been selling Toyota parts for something like 25 years.

So, he stocks the bearing. My price, with tax, was $5.73. I might have bought the bearing cheaper at NAPA, but I like my local dealer and give them my business when ever I can (which is most of the time).
