The primary function of the crankshaft in your car or truck’s engine is to transfer power from the piston to the transmission, which then transfers it to the wheels so you can drive. Therefore, if you notice any of these signs that your car’s crankshaft is failing, it could indicate that your vehicle will soon break down completely, requiring repairs and potentially even replacement parts that could cost thousands of dollars. That’s why it’s essential to watch these signs and take action before you end up stranded on the side of the road.
What is a Crankshaft?
The crankshaft is located low in the engine near the oil pan. The function of the crankshaft is to transfer the up and down motion of pistons into a rotational motion that can be sent to the transmission. Pistons are attached to the crankshaft by connecting rods. The crankshaft allows these connecting rods to move in a circle that turns the crankshaft. The crankshaft is exceptionally sturdy and must be able to withstand tremendous forces that are produced by combustion inside the pistons.
Signs of a Failing Crankshaft
While crankshaft problems are rare, they can happen and are usually severe. Most crankshaft problems occur due to faulty manufacturing, or one or more of the bearings going bad. If your car’s crankshaft is failing, you will usually notice vibrations while the engine is running and even difficulty starting the engine. In addition, you may hear a loud knocking noise while the engine is running or see the oil pressure drop too low, triggering a warning light.
What Can be Done About a Failing Crankshaft
Unfortunately, crankshaft problems are significant mechanical problems that usually require expensive repairs. Initially, your mechanic will need to disassemble the engine to examine the crankshaft and related components. In some cases, repairing or replacing the crankshaft may be a good option depending on the vehicle and any damage that has been done. However, in some cases, a failed crankshaft will result in total engine failure, necessitating replacing the engine. Fortunately, these cases are rare as crankshafts typically last the life of your vehicle without any problems.
If you notice any signs of crankshaft failure, see your trusted mechanic immediately before severe damage is done to your car’s engine. While crankshaft problems are usually costly repairs, failing to take action immediately will be even more expensive.
