Thrust on a crankshaft is the distance (in thousandths of an inch usually) that the crankshaft can be moved forward and backward. Generally you can take a pry bar and try to push the crank pulley back and forth and it should not move noticeably. If it does then you have a problem. You can measure the travel with a feeler gauge if you drop the oil pan or use a dial indicator on the pulley.

I doubt the vibration is from crank thrust because that's not a symptom in most engines. Hard to say without knowing the make and model of the vehicle.

I think they meant Thrust bearing or Thrust bushing.
It will most likely need to be replaced.

Vibration have nothing to do with the trust.
Trust endplay is the distance the crank-shaft moves axial from going forward verses back before it catches its torque.
