Under what driving conditions do it occur? Any changes when you put the trans into neutral while driving and let it roll?

I now have about 3,000 miles and it has been progressively worse. I am chiming in because I have not only found the cause of 3 different vibrations, but the cause of intermittent vibration. 1 cause is when the engine drops from v8 mode to 4cyl, you will feel an engine vibration like the engine is mis-firing. This is normal. The second vibration I have found is that if the tires do not get a true, full width balance, at high speed the whole truck will get a shake in which you can even see the side mirrors get blurry do to vibration. Even just a static balance will cause this. The third and most important vibration that I have found is because of the drive shaft. The drive shaft is built with a sound resonator inside of it that has been progressively breaking apart since day one, causing the vibration to progressively get worse as more of this resonator breaks apart. So now with pieces bouncing around in my drive shaft, every time the drive shaft spins up, they catch in a different spot, causing the balance to be different every time I stop and go. My truck is now at the dealer, who is ordering a new drive shaft for me, so hope fully this is the end of my problems. I hope this helps others out there.

I noticed a high-frequency vibration between 60 and 75 mph I immediately took it to the shop thinking a tire was out of balance
The shop balanced my tires and I still had this issue. There is also some sort of harmonics going on that simulates one window down while driving on the highway. Everything else about the truck is completely awesome. Is there a fix or do I need to go get my money back from GM.
