However I did also notice an odd feeling from the front right caliper when I had to get on the brakes hard once. I recently did the left front as it was sticking. I'm thinking the right front might be too. That could potentially be a contributing factor as well.

ive been through the same thing as you albeit with a much newer car and much lower miles. after tons of road force balances, new tires, etc., i swapped out my LCAs for dirt kings and all of my vibrations and steering shimmy instantly disappeared. lots of folks on here will tell you that its always the tires, and yes a perfect road force balance will really help if not cure everything for quite some time. that said, i'm of the opinion that the stock bushings are way too damn soft which is why tires must be PERFECTLY balanced. Ive never had this issue with any other car or truck. also keep in mind that if you go to poly bushings or dif LCAs, your ride quality is going to firm up some
