Default A wr on squealing!

im sure you guys understand, it just sucks. I had issues for a long time with alternator locking and squealing but I got a new one. it has been great for about a year. I just got a new serpentine about a year ago.

it recently began to squeal at idle or low rpms when the engine has warmed up. I sprayed the belt with treatment to help stop squaling and it didnt help.

could it be a bearing on one of my wheels under serpentine?

Does it squeal all the time or just when it warms up? It could be a bearing,look at the idler and ac pulley. Might try and poor a little water on the pulleys,if it is the belt it will stop the squealing for a short time and then start again.
