I just saw a thread about a week ago with part numbers for this bearing but I can't find it... if someone has the link or the part numbers I would greatly appreciate it... the noise is driving me crazy!

 

What pulley?

 

If you are talking about idler bearings, I recently changed some using Timken 203PP.

 

You can find the bearings at Grainger, I did an idler on my wife's Nissan Altima for $5 and an extra 5 mins of labor, versus the $50 that Nissan wanted.

Often on the old bearing, it will be labeled on the side. You can crossreference the part number with Google and find a good substitute.

 

Thanks guys for the responses... I used the info that jdonnell posted
