First I would think the sway bar links are failing
Second, the upper strut mounts might be failing. Good thing you can buy quick struts or their equivalent for a Taurus
Third, the Taurus is prone to front lower ball joint failure. There might be no lateral ply, but there may be vertical play. Pry between the ball joint and steering knuckle to check.
Fourth, pry against your control arm bushings. You should really have to put some effort into making them move 1/4 of an inch. If they move easily, replace the control arm or the bushing.
Also, keep in mind that since I live where there is no road salt, there may be other parts that can be a problem that I am not aware of, because I rarely see cars exposed to that stuff.
