I have a 2010 SES with 80,000 miles. A few months ago, it started making a howling noise. At first, I thought it was cupped tires, but now I am thinking wheel bearings, because it makes a noise at nearly all speeds, although when I am going less than 10 or 15 mph, it's more of a growling than a howling (lower pitch). I jacked up all 4 wheels and checked for play and found absolutely none. I also did the half shaft test where you crank the wheel hard and lightly accelerate while listening for noise and heard none. What does the brain trust here think? Front wheel bearings? Is this common on these at this mileage point? It seems like it's coming from the front... Any known issues with the rear? Thanks for the help!
