Good bet it is! Probably the A/C pulley bearing.

Something that you may also want to check is if the pullies are worn in a u shape, u don't fit v well.

It's an important belt to drive the water pump. Without that belt, the power steering belt is driving everything....PS, Alt., & Compressor.
I wouldn't drive mine without that belt installed.
There are several threads concerning the rear belt, size, and how to install.

Yes, they all come off. You'll find that many of us will remove the water pump pulley, put the belt on the crank, then the wp pulley and get it onto the wp studs.

Now that I have confused you have fun.
