Hi Guys, I have my 2009 Avalanche Front Wheel Howling Noise at high speed (from 60km/h to 120km/h). Mileage : 100,000Km

I've checked so many sites, but everyone is talking about Wheel bearing. So I changed it, but noise is even more now. Yesterday I see a truck with wheel bearing noise (now I got it), but definitely mine has no problem with wheel bearing.

It's only noticeable when I closed all windows, turn the a/c off, turn the radio off. Since I have noticed it, I feels it's getting noisier and even I think I feel some vibration.

Any idea or experience like me? I have camping coming tomorrow in the states, and need to pull 7200lbs RV for 10 days, think there will be no problem???

Just play the music louder, you will eventually figure it out.   :D

Are you sure it is coming from the front.  I could have swore I had a front brake grinding but when I pulled the wheels it ended up being a rear.
