Compressor pulley was making a loud noise and the front plate came off

Welcome to 2CarPros.

I have to be honest, it isn't a five minute job. You don't have to remove the compressor, but it will be tight to complete.

I attached several pics below. Within the pics are the directions for both removal and replacement of the pulley. They aren't what I would consider specific enough, but this is what they offer us.
