The invention, which relates to the field of vehicles, provides a method and system for measuring the axial clearance of a crankshaft and a vehicle. According to the provided method, after a vehicle stops working, a first distance between a second crankshaft counterbalance and a side wall, away from the second crankshaft counterbalance, of a second thrust plate is measured when the second crankshaft counterbalance supports the second thrust plate; a second distance between the second crankshaft counterbalance and the side wall, away from the second crankshaft counterbalance, of the second thrust plate is measured when the first crankshaft counterbalance supports a first thrust plate; and the first distance is subtracted from the second distance to calculate an axial clearance of a crankshaft. According to the invention, after the vehicle stops working, the axial clearance of the crankshaft is measured to monitor the axial clearance of the crankshaft in real time, so that a phenomenon that the engine is damage
