2008 Hummer H3 Q&A

2008 Hummer H3 Question: What are some possibilities?

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. -
Answer 1
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. -
Answer 2
