Road Noise/vibration Disapears With Left Turn?

[dichdoc]

2007 Chevy 2500 HD Duramax Crew Cab SB. Developed a road noise hum from 20 mph to 80 mph does not seem to change with speed. It completely goes away with a Left turn (curve in interstate, etc.) Doesn't seem to take a whole lot of pressure to get it to go away. It is constant while straight or turning right. Tires are BigO TA's have not had a problem with them in the 15,000 miles I've had the truck. The truck has just under 70,000 miles. I am going to try rotating tires tomorrow but I'm thinking bearing??? Which side would it be and would it be covered under the 100,000 mile warranty? Thanks Travis

is the tire wear even? i don't know if the warranty will cover the wearing if it is truely that but it never hurts to take it to the dealer, and see if they will warranty it anyway...

jacked the truck up to rotate tires and could wiggle the Passenger front wheel almost 1/2". Lug nuts were tight. Took it to dealer and new bearing was under warranty. Good as new and free. With the government owning gm using the warranty felt alittle like taking welfare...
