Puzzling to me because it's usually at higher speeds at a higher throttle percentage. And it's almost like you feel it more in the dash and then you do in the steering wheel or the gas pedal. You do feel it in both of those things to a certain degree but man that dash feels like it's going to shake right out into your lap. I guess it could be the lower control arm bushings but I would have never guessed they can cause such a violent shake
