Hello all,

2003 AWD Astro Van hums very loud at all speeds, when I turn the wheel to the right just a little it goes away completely. I can keep turning the wheel all the way to the right and nothing (no vibration) but when going straight or left its there. It doesn't really vibrate but makes a loud humming sound. I changed the right wheel bearing and still no difference at all.

Thanks in advance,

 

Does the humming only happen when the vehicle is in motion? Where does it sound like the humming is coming from?

 

Did you check the other wheel bearing because that sounds exactly like a wheel bearing issue. Being that these bearings are like 3-400 bucks im sure you dont just want to go and change it for nothing but Ive had the same problem on 2 of my astro vans and it was wheel bearings. It wouldnt hurt checking the level in your front differential but I dont see why it would only make noise turning one way if it was that.
