2007 classic 2500hd highway vibrations
 

I've searched the threads and was unsuccessful in finding a solution or similar symptoms that I am expirencing. I have a 2007 Chevy 2500hd classic ext cab 4x4 6.0 engine. Up until recently, the truck has been flawless. Now, while on the highway, I have a vibration anytime my foot is on the acclerator over 60 mph (maintaining speed and increasing speed). When I take my foot off the gas pedal, the vibration stops. No vibrations on braking, only on the gas pedal. I can feel the vibrations through the transfer case shifter when I put my hand on it on the highway (not shifting the transfer case, just feeling around for the vibrations). Since the vibration started, I have rotated the tires and replaced all the brake pads (just regular maintenance) and the vibration issue did not change.

Any information would be a great assistance.

Any other ideas?

your vibration could be caused by a bad universal joint, usually inexpensive fix.

Thats where I would start looking. And you cant be sure by looking or shaking,you need to remove the drive shaft.
