My truck has a brutal an di mean brutal vibration coming from what i think is the front end. Seems to only happen when i accelerate, and i feel it vibrating right down the steering shaft to my steering wheel.

I know its not my tires, i know my truck and the feel of it with mud tires it never did this before. Seems to only be under acceleration which makes me want to believe its drivetrain related, just have no idea what it could be but its annoying as hell and dont want anything coming loose!

 

im wondering if it your new under drive crank pulley. the new one does not have any type of harmonic balance does it?

 

hmm im not sure?
