What Is a Dual-Mass Flywheel?
The dual-mass flywheel is why some clutch jobs cost more. A Cranbourne West specialist explains.
What it is & what it does
A dual-mass flywheel (DMF) sits between the engine and clutch and uses internal springs to absorb vibration, making modern manual and dual-clutch cars smoother and quieter than an old solid flywheel could.
The trade-off: it wears out, and it’s usually replaced at the same time as the clutch — which is why a clutch job on a modern car costs more than on an older one.
Signs of trouble & how we help
Signs of a worn DMF include a rattle at idle (especially with the clutch out), vibration, or a juddery take-off. It’s often worth replacing with the clutch to avoid paying the labour twice.
We assess the flywheel when doing a clutch and advise honestly whether it needs replacing — not an automatic upsell.
