2008 Pontiac G6 GXP, 3.6L V6 sedan
I have a 08 Pontiac G6 GXP with a front end vibration issue. Replaced all 4 wheel hub assemblies, both front struts assemblies, entire cv axle including the intermediate shaft. Both front brake calipers, rotors, brakes, sway bar bushings, sway bar links. All brand new good year tires balanced and alignment. Motor mount was replaced as well and I am still getting a vibration coming from the car when accelerating and sometimes a bumpy ride at highway speeds on a smooth brand new road. Only 77,350 miles on the car and I replaced the Transmission fluid, spark plugs. Any ideas why this is happening or is there a fix. I think it could be the transmission gear differential part causing the vibration. Any ideas anyone.
