It vibrates like it`s a resonant vibration. Very violent vibration. I will upload a video tonight. I have looked at Pulleys and belts, Balancer, New plugs and wires, The car is tuned perfectly. I`am at my wits end with this car! I even thought the steering box was loose, Nope! K Member is tight! The steering box is new! Hoses are new! I have covered every aspect. Odd how I disconnect the belt to the pump and all that vibration energy goes away. Was going to buy a new or reman pump, but they are like frogs fur at the auto parts store.
