I'm not sure if this was brought up before or ever but I just replaced the rear tires because of flat spots, and I thought it was causing the louse truck like noise. After I replaced with new tires I'm still hearing this loud noise on the highway. I currently have 84K on a 2010. Any ideas?
One way to find out, is to (carefully) turn while rolling, and see if the noise goes away. For example: if rear driver hub is suspect, turning car a sharp left will temporarily take pressure off left side of the vehicle, and hub noise may go away.
Went to the dealer, I forgot when I bought the car certified used I had an extended warranty with a $50 deductible. So they will replace the left rear wheel hub when the parts come in next wednesday. Thank god!
