Default Idler bearing replacement input

(1971 LS5 with AC)
When I pulled my PS pump I noticed the idler bearing doesn’t sound 100% to me. It’s not got a lot of movement but sounds fairly dry. Kinda un decided on finding bearings or buying the bearings already pressed on the shaft and just re using the bracket and wheel. What is the best way to get this done?

I don't believe the bearing is serviced separately. 3952332 is the GM part number for the pulley assembly.

I replaced the bearing in mine many years ago and it basically is just a water pump bearing. The bearing that I installed was made by Everco out of St. Louis and the part number was A8632. I bought it at a local auto parts supplier.
It was made in Canada and has lasted many years. If you find one you can press the old one out and press the new in. Just make sure that you make measurements so that everything lines up correctly when you are finished.

I just looked online and Zip carries them along with several other suppliers. Price has gone up considerably (approx $90) since I bought mine, but they are available. Still cheaper than the whole assembly. Might want to check your local parts store first.

Excellent info!

It makes sense it was a commonly used bearing.

Great video.
SO.... if you can figure out which of those 2 "long" pulleys is the equivalent of that Everco a8632 then the video website has the bearings available for 58.95.
seems like GM, Ford, and AMC used that A8632...
I suspect it is one of these:
