When the indigenous crankcase shaft is worn, the metal clatter of the deaf tone appears in the engine of the VAZ-2110. The sound of the crankshaft shaft was audible at the sudden opening of the throttle. At the time of motion, its frequency shall be increased with the increase in speed of the crankshaft. If in the crankshaft there is an exorcating pattern, there will be a more sharp knock, with irregular gaps. There will be such extraneous noise in light of a smooth increase or decrease in speed.
