Not trying to be a dick but if you know the answer to your problem then why post the question? I've heard of suspension components, drive line components, and wheel bearing causing front end vibrations, but not a torque converter that is new to me. Usually when your accelerating and there is a wobble then let off the gas and it goes away, the most common problems are u joints going out, RWD, or a cv joint going out, FWD.
