That’s a great suggestion CTH, that would tell me if it was motor mounts or transmission mount. I did check the outer wheel bearings awhile ago and they looked fine. If this test eliminates the mounts, I will go after the tie rod ends next. I would hope the person who did the front end alignment would have found any issues with the king pins, but I am not that knowledgeable regarding those parts.
