So i replace the left front and the rear wheel bearing and its a lot quieter. But its still humming. The noise goes away when i make a right turn putting all the weight on the left side. What can it be BAD parts maybe?? Should i take it off and return the parts for a new one? I purchase them both at Oreilly Auto. This is on a 2002 Acura TL-S

 

Have a mechanic drive your car and tell you. There's no sense in trying to translate noises into text and playing the guessing game.
