Jack the front wheels off the ground (support it securely w/ jackstands), and have someone shake the wheels while you lie under the car, and feel each of the four linkage arm ends, in turn. There are two bushings at the chassis end of the links, and ball joints at the wheel ends. Total 8, two bushings and two ball joints on each side. On my car, three of the four had noticeable play, on each side. Replaced them and the problem went away. Just got back from towing my motorcycle on a trailer from south Florida to Lake George, NY, 3000 miles total, NO PROBLEM! Forget about the balance - get under the car, and check the bushings and ball joints! (Insanity is defined as repeating the same actions, and expecting a different outcome.)

The problem is i did replace those parts all of them at once and still had issue. Now i know i bought the cheap kit off ebay so i replaced the LCA with brand name and still had same issues. The second step was the good year tires were actually out of round so after replacing them with michelins the problem was softened but still there. after alignment and rebalance things were good for like 3 weeks and its back so the only bushings left are the trust arms from the cheap asian/german company but i did as you said shake the wheel and there is no play in them non. However, i ordered 2 upper arms with bilstien and ball joints so thats it no other part is left thats from the cheap asian/german kit. I can say my steering rack those make a click but its definitly from the u joint in the column i can feel it tic toc when turning left to right etc. the left whole axle with CV joint was replaced also because it was very loose and the right is only 2yrs old dealer replaced it in the end of 09 and its still very tight and no play. i will see midweek i shall have the parts in and replaced. we will see I really hope this is it.
