while your testing the hubs grab the fron tires at the 9 and 3 o clock positions, then push and pull the wheel side to side, if it moves, you need tie rods.

take the wheels off, check the sway bar end links, and the sway bar end for cracks, and look at the rubber bushing in the sway bar cap on the frame, just follow the bar to it.

also take a look at the bushings for the lower control arms you'll see the one clearly with the tire off, if its all torn up, you need a new pair of lca's. they are cheap at 42 bucks a side on line. its a whole new lca, comes with 2 new bushing and the ball joint.
