Serpentine belt idler pulley pn?
Hello all,
I've spent 2 hours looking for a part number for the idler pulley on the drive belt (serp belt, not timing belt) on a 96 LS400. Its the very top pulley of the bunch, not the tensioner pulley. (This is called the idler pulley, right?) I think its made by Dayco. Couple of places I called today have no details or info.
Anyone have a part number for either the pulley or its bearing?
Many thanks!

Actually all you need is to press the bearing out and replace with a fresh one.
Mine was was squealing and when I removed it, one of the internal bearings could be heard rattling inside. Since I was leaving on a trip and this came on a later Friday afternoon, I didn't have the leg time to call bearing shops. I just bought the whole unit.

Thanks for that! I want to write some notes here so that others may do this, but right now I am not sure if all the references are correct. I found a link from your part number to the bearing itself, which, as far as I can see, is sold in stock at autozone! Here is the link:

This points to Napa part # 6203:

There is a reply in there showing the bearing number is 203FF, which is sealed on both sides, according to:

Here is AutoZone's part:

I will pick one up tomorrow and attempt to replace my worn out one. More later.
Thanks!

The right bearing is the 6301 DWA (6301 sealed both sides). I can read it on the old bearing itself.
The 6203 bearing is for the tensioner bearing on the same belt. I replaced both - here is a link to the part numbers and more details:

And here is a pic of how the tensioner bearing came out - the idler bearing was still holding together (though a bit rough), but the tensioner bearing had disintegrated:
