Front Tire Noise

I have an 02' Yukon that has a very annoying tire howl in the front. The front end has been checked, and is OK, in term of being in alignment. My uncle has an 01' Tahoe and he has the same problem. You can actually see the unusual wear on the front tires. I believe the front suspension geometry is the culprit, but what can i do about it?

Do you have oversized tires or anything aftermarket down there? I'd take it to a 4WD specialty store and have them look it over. They'll be able to give you a better idea of whats really going on becasue they'll know more about the geometry and what works the best. You'll probably pay a little bit for the service, but usually not much more than the dealership - and you'll get the results you want.
