Vibration at highway speeds.

[Socalover1]

First time posting.
My 2009 Genesis 3.8 vibrates at highway speeds. It has 94000 miles and using Firestone tires. I had the wheels balanced twice and an alignment done. Someone mentioned that the driveshaft bushing is probably the cause. I tried getting the bushing from the dealer but they will only sell the complete driveshaft. Any help will be appreciated.

Long story short, besides getting an alignment, all 4 rims were bent and I got them fixed, followed by road force balancing. During balancing mechanic showed that driver front tire had a concave dip from possible improper inflation so rotated that out to the back. Saw a significant improvement overall. Just after a year I have gotten the tires rotated again, will check to see if that tire is causing issues again, now that is back in front.
