What to Do for a Noisy Flywheel

by Ben LeDoux

Noisy flywheels can become a nuisance to drivers during their everyday commute. It can become necessary to do something about the noise. However, finding the problem of what is wrong with your flywheel involves a great deal of work. Noisy flywheels are the beginning of telling you all you need to know about the inner workings of your vehicle.

Why the noise and grinding?

When your clutch engages into gear, it connects with the flywheel to begin motion of your vehicle. After several long miles and possibly a couple of bad gear shifts along the way, the contact points of your flywheel can become worn and cause the car not to shift as well as it used to. Continuing to drive on this will instead only cause more harm than good, as it will struggle into gear and continue to wear on itself and the clutch.

How do I fix it?

There are two ways to remedy this problem. If the flywheel simply looks worn and has no major cracks or damage, you can try to have it resurfaced. Flywheel resurfacing is a process where it is run through a machine to make the surface of the flywheel smooth and take out any indentations that could cause the noise. This is the cheaper option, although if there is damage on the flywheel and it is cracked, then replacement is the only other option.

To replace a flywheel, you will have to remove the transmission and open it in order to get to the flywheel assembly. This is a very complex task that should only be done by an experienced mechanic. While the flywheel itself doesn't cost an arm and a leg, the installation process is very involved, and this means spending a good amount of money for a mechanic to handle the replacement, which can cost anywhere from $800 to $1100.
