No, the crankshaft does not directly affect the steering of the vehicle. The crankshaft is responsible for converting the reciprocating motion of the engine piston into the rotating motion of the driving wheel. The steering system, on the other hand, is responsible for controlling the direction of the wheels and turning the vehicle. However, the crankshaft affects steering indirectly because it is responsible for providing power to the engine, which in turn provides power to the power steering pump.

Yes, the crankshaft is connected to the engine's transmission and helps drive the engine. The crankshaft is connected to a flywheel or flexplate, which is then connected to a torque converter or clutch assembly.

Vibrations: You may feel vibrations on the steering wheel or the floor. Loud noise: If the bearings on the crankshaft wear out, you may hear a tapping or crashing sound from the engine. Loss of power: A damaged crankshaft can also cause the engine to lose power. Difficulty starting: If the crcrshaft is severely damaged, the engine may have difficulty starting.

The main cause of crankshaft failure is excessive wear or damage of the bearing supporting the crankshaft. Other factors include overheating, excessive vibration, lack of lubrication, and manufacturing defects.

Surface finish: the surface of the crankshaft should be free from any cracks, scratches or other signs of wear. Beat: The beat of the crankshaft, or the degree to which it deviates from the true rotation, should be measured with a dial indicator. Any excessive beat may indicate bending or damage to the crankshaft. Journal Diameter: The diameter of the journal, or the area where the crampshaft bearings are located, should be measured to ensure that they are within the manufacturer's specifications. Bearing clearance: The clearance between the crankshaft and the bearing should be checked to ensure that it is within the manufacturer's recommended tolerance. Fillet radius: The fillet radius, or the curve where the crankshaft journal meets the web, should be examined for any signs of crack or damage. Straightness: The straightness of the crankshaft should be checked to ensure that it is not bent or twisted.
