IVE GOT A 04 V70, HOW DO I CHECK TO SEE IF MY WHEEL BEARINGS ARE BAD. I AM HEARING A HUMMING OR NOISE WHEN I DRIVE, IT SEEMS TO BE COMING FROM THE WHEELS. I READ I FEW THREADS ABOUT THE WHEEL BEARINGS THAT GO BAD. HOW DO I MAKE SURE WITHOUT TAKING IT TO THE DEALER.

 

If it is humming then either it is the Bearing or a tire.
First swap front and rear tires and see if the noise changes.
