Forgive my ignorance, but I really don't know much about suspensions, alignments, and various related things.
Anyhow I went in to get my tires rotated and balanced (god I hate those weights), anyways I had some shudder above say 75 mph (with my foot on and off of the gas). Now it seems to be worse then before.
Which makes me wonder if:
This only highlighted something else wrong, that requires more work
-or-
The balance was done incorrectly
BTW the car has just hit about 16k.
