I rotated two wheels and still have what I'm now going to call a drivers side front shake/wobble. Seems rather severe for such a quickly occurring event. It's so severe that I'm concerned about driving it 90 miles. While having the tire off, I find it very hard to feel wheel bearings or ball joints being a 3500 4x4. Having done these on smaller vehicles, I could "feel" and fix them. Thoughts? Thanks!
