I have a 2006 500ss which has a loud squeaking when near idle. I think it is the drive pulley but am not sure what to do about it > I am going to change the belt to see what that does. If I need to take the drive pulley assembly off how complicated is this ? I do have decent amount of mech knowledge but do not want to get into some thing the average guy should stay away from. Any ideas of how I can check for what is making the sqeak?
