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. - ChuckH3
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. - csubak30
have rear hub bearings ck'd - globalhelper
that's as clear as I can get, I don't know what at least 10 characters mean?
