I did a search using the part # for the front hubs in Alloro's post. They turned up on Amazon for $93. Seems to be manufactured by Precision Automotive. When I was a young-un I was told by my father-in-law (a machinist) that you couldn't do better than Timken and I've always had good luck with them (for serviceable bearings). I've found the Timken for a little under $200 on ebay and $162 on Amazon.
What's the popular opinion on this? Is Timken still a high quality part? Worth 2X the cost of the Prec Auto?
Inquiring minds and all that jazz.

 

I have 106,600 miles on my '04 EB. It just started making this sound too - almost reminded me of an old true lcking diff binding. Only seems to do it on sharp turns from a stop. Started about 2,000 miles after I had all the transmission and differential fluids changed.
