Is replacing a flywheel expensive?

Replacing a flywheel can be a relatively expensive repair, depending on the specific vehicle and the extent of the damage. Flywheels are an essential component in the drivetrain of a vehicle, and their replacement can involve significant labor and parts costs.


What is a Flywheel?


A flywheel is a heavy, rotating disk that is connected to the engine's crankshaft. Its primary function is to store and release energy, helping to smooth out the uneven power delivery from the engine's combustion cycles. Flywheels also play a crucial role in the operation of the clutch and transmission in manual-transmission vehicles.


Why Would a Flywheel Need Replacement?


Flywheels can wear down over time due to normal use, or they can become damaged due to issues with the clutch, transmission, or other drivetrain components. Some common reasons a flywheel may need to be replaced include:



  • Excessive wear and tear from normal use

  • Damage from a slipping or worn clutch

  • Damage from a failed or malfunctioning transmission

  • Damage from a sudden impact or collision


If a flywheel becomes excessively worn or damaged, it can cause issues with the vehicle's performance, fuel efficiency, and even the lifespan of other drivetrain components.


Cost of Flywheel Replacement


The cost of replacing a flywheel can vary widely depending on the make and model of the vehicle, as well as the specific parts and labor required. On average, the parts cost for a flywheel replacement can range from $200 to $500 or more, while the labor cost can range from $200 to $500 or more, depending on the complexity of the repair. In total, the cost of a flywheel replacement can range from $400 to $1,000 or more.


It's important to note that the cost of a flywheel replacement can be higher if additional components, such as the clutch or transmission, also need to be repaired or replaced as a result of the flywheel issue.

How many hours does it take to replace a flywheel?


Labor time is about 7.5 hours and this job can easily take a day to do. If you are doing it yourself in your driveway you are looking at a day and a half to two days depending on your tools and ability.



Is replacing a flywheel a big job?


Yes, ​flywheel replacement is an expensive job because it is a labour-intensive process. The flywheel is located at the back of the engine and is attached to the crankshaft. In order to replace the flywheel, the transmission must be removed from the vehicle and the entire process can take up to 10 hours!



What noise does a bad flywheel make?


VIBRATIONS AND METALLIC RATTLING SOUND AT IDLING SPEED
Another way to check is to depress the clutch pedal also at idle speed. If the metallic rattling disappears, the problem is most likely with the flywheel.



Will a car still start if the flywheel is broken?


PROBLEMS STARTING YOUR CAR
When you turn on your engine, the starter motor pushes a gear towards the flywheel. This gear meshes with the flywheel's teeth to make the engine turn over. If one or more of the flywheel's teeth are damaged or broken, then the wheel can't engage with the starter motor.



How long will a noisy flywheel last?


around 80,000 to 100,000 miles
How long will a noisy flywheel last? If your flywheel is making an unusual noise, this is a sign it has worn out and needs replacing. Flywheels usually last around 80,000 to 100,000 miles, sometimes more.



What does a bad flywheel feel like?


If you notice vibrations coming from your clutch pedal, or even worse, from the floor of your vehicle, it's a symptom of a failing flywheel. One of the flywheel's purposes is to absorb vibrations, so if it's not doing this, it will need to be replaced before it causes further damage.



What happens if you don't fix flywheel?


A burning smell
It comes from clutch plate wear and tear, which can be caused by a warped flywheel causing too much friction and heat. The clutch will likely stop working if you don't replace your flywheel.

Is it OK to drive with a bad flywheel?


Safety Risks: Driving with a compromised flywheel can pose safety risks, especially if it leads to sudden loss of power or control of the vehicle. If you suspect that your flywheel is warped, it's best to have it inspected and replaced by a qualified mechanic before continuing to drive the vehicle.



Is it worth replacing a flywheel?


You don't have to replace the flywheel if it's in good condition, but there's no way to tell without a direct physical inspection. If it's lightly glazed or scored it can be resurfaced, but if it's heavily scored, blued from heat, or cracked it's junk.
