Idler/bearing type pullies

Quick question-

I put in a new AC idler pulley and I’m hearing a whirring sound that I think I’ve isolated to that pulley. My question is, do these kinds of pulleys need to be greased pre install?

no it just be a bad pulley or bearing i should say

Ah damn it lol

Thanks John

no problem kid

You have t-tops no need for AC… yank that shit

Exactly what I was gonna say!

T-tops off in traffic= 20+ degrees hotter inside.

I’m not going to front, I like my creature comforts haha
