C4 vibration at 60mph - torque tube bearings?
I have vibration at 60mph. You can feel it at 40 and up to 90 but its worse at 60mph. I have tried two sets of wheels/tires without change. I have new axles and wheel bearings, shocks and shock mounts. New trans mount and the vibration remains. I have swapped my wheels/tires from my other car and the vibration remains and does not move to the other car. I'm running out of ideas on what else it could be.
Very frustrating. Wondering if the bearings in the torque tube are worn??? Has anyone had to change them? If so, what is involved in doing so?
