High speed vibration
Hello I am hoping someone can give a second opinion/ suggestions for my issue I’ve been trying to figure out for some time. I’m experiencing aggressive vibration/shaking on the floor, seat, shifter and steering wheel when accelerating past 140km/h (87mph). I rechecked alignment, tire balancing and re torque suspension/mount bolts, no play in suspension components.
