all you can really do is jack it up and start checking out each part, use a pry bar to see if you can get movement form the ball joint area, and the lca bushings.
with the tire still bolted on, and the tire jacked up, grab the tire at the 9 and 3 o clock positions and push and pull the tire, if the tie rods are bad you will feel it move, maybe even feel a click, when normal it should move a small amount but feel tight when rocked back and fourth.
check the sway bar ends, and the links.
if you pop your hood, start the car, and rock the steering wheel left and right, and watch the tops of the struts, if the center bolt is moving you need new strut mounts. like the whole center part that is.
while your there take a good look at your brakes, if one caliper is hanging up, aka not un clamping the rotor, the brake will drag and cause a vibration as well. warped rotors would give you a good vibration while stopping. re greasing the caliper sliders bolts usually fixes this.
and then there is always a bad axle possibility, or real bad wheel hub/bearing.
