My 2000 Grand Marquis pulls to the right and has a front end shake/wobble which seems to be worse at lower speeds. I just got this car a couple weeks ago and the previous owner supposedly just did both front wheel bearings and had an alignment. The passenger side front tire has some wear on the inside edge but not enough to make me believe this could be the source of my wobble or the pulling to that side. What parts of the suspension should I check or should I rotate the tires and see if that helps?
