Recently put new set of tires on. Now I'm hearing a roaring sound coming from the rear, sounds like I have mudgrip tires. At first I thought the tires were the problem, but had them checked and discovered the noise was coming somewhere in the rear and not the tires.
What are some possibilities? on 2008 Hummer H3
A roaring noise that gets louder with speed (does not cause vibration though) is usually the wheel bearing that has failed and needs replaced. Also called hub bearings.
have rear hub bearings ck'd
