So…. whining and tapping… Look on you tube and it is an alternator decoupler pulley part.Whic has ball bearings in it and is probably shredded. So.. the part is $40,and to put it in cost $600! LMAO…. no thanks. I will do it myself…. it will take like 6 hrs the vid said due to a very stubborn screw on the compressor that has to be taken off. Gee looking forward to it! Have to replace belt while I am at it.
