If you have a single belt coming off the crankshaft pulley and it's obvious the pulley it's driving is going slower, then it is the harmonic balancer pulley. The two parts can still spin and not separate due to in being a "V"shape internally. You can check for slippage by using a bright gold or white marking pen and draw a straight line from the center big nut to the outer edge of the crank pulley face. Once this is done, run the engine for a minute and the check the line you have made. If the line separates, then you'll know it the harmonic pulley. Does your one belt also drive your alternator ? Believe me, those harmonic balancer will squeal when worn out. The rubber spacing just get old, stiff and cracking until it separates. Harborfreightools sells a mechanics stethoscope for under $5 and is the best tool for finding engine noises as the engine runs. Lets us know what you find.
