Not trying to derail the thread, but how can you tell exactly what the culprit is? As I mentioned-- I had the tie-rods and control arms replaced and also replaced the front rotors and pads with stock rotors and Pagid. After this I noticed slight shimmy when braking lightly form 70mph to 35mph. I suspect the rotors, but also suspect front shocks (there are 200k miles on these). The shimmy is getting more noticeable--
