Well guys looks like I had quite the situation with the vibrator. I have a 2014 high country 6.2 and noticed the dreaded shake at 75 mph. I have 7500 miles on the truck. Brought it in to the dealer. They were more then willing to try to fix this. I let them know how much I've read up on the problem and that I wasn't confident. They first tried balancing the tires,,,no luck.. Then new tires,, no luck. New wheels and tires,,,no luck. Rotate the drive shaft,,no luck. Then they told me my drive shaft was way out of spec and that they had a new one on order. While waiting for it to come in, a delivery driver at the dealership ran INTO MY TRUCK!!! damaged the front right side pretty good. They replaced all damaged panels with oem replacements. No dent repair. After the fix they installed the new drive shaft and left me with the new wheels and tires and what do you know???!!!!! NO MORE VIBRATION!!!! Now rides like the dream I always hoped it would be. Couldn't be happier. Hopefully some of you guys have similar luck. Don't give up!
