As you understand it, nothing. But tire balancing may resolve his problem.
That is because people are not always precise in their understanding and use of words. And since he used all three words, perhaps he does not understand the word "bucking" in the same way that you and I might. That'* one of the things that makes diagnosing real-world problems in a text-based environment difficult.
Let'* help by saying that bucking is generally understood as a sharp jerk that occurs in a random manner (irregular frequency) like the last kernels of popcorn popping, and differs from a vibration that occurs with a more regular frequency (like a massage chair). Shaking of the car can be produced by either vibration or bucking.
While bucking is often caused by an engine miss; vibration or shaking, especially as described, would be more likely a balancing issue, like a wheel, or bad drive axle.
