well for the last two weeks my cars being making this loud hollow whistling sound from the back , at first i thought it was my back wheel tyres nearly being outta tread soo ti could be close to running on metal but then i changed them today and the noise is still their , i want to see if any of you guys know whats the problem first before i take it to the mechanics...

could be bearings all could be a range of whole other things, jack ur car up have a look around underneath see that everything is tight and running smoothly
