Please help, front end shimmy survey

[Decsr]

I have to make a correction to my last statement. I have had my tires balanced, a week or so back when I had to change my wheels to the factory style steel wheels, but I still didn't rotate them. I must be getting forgetful in my old age

i have a 2001 limited auto, it also has this feature

My 07 has this "feature" as well. It even has a ferocious growl when turning left which comes from the front right.. I even got the "64 Ford" package with the typical ford A arm bushing squeak when going in/out of driveways or over speed bumps.. real attention getter!
Going in for service to have this looked at on Wednesday.
Seems the shimmy is more exaggerated with the chrome smoothies on and not the stock rims. I read back a few posts about bevels or washers or something.. I will have to check that, maybe there is something I missed when putting on the summer smoothies/wide whites.. going to change them back before Wednesday so the dealer doesnt mess up my rims/tires.
