Dual-Mass Flywheel Replacement in Sunbury-on-Thames
Many diesel and higher-torque petrol cars use a dual-mass flywheel to absorb engine vibration. As its internal springs and bearings wear, it can rattle, vibrate or knock.
We confirm flywheel wear before recommending replacement, often alongside a clutch.
Common signs
Symptoms worth checking
- Rattle at idle that changes when the clutch is pressed
- Vibration through the pedal or floor
- Clunk when pulling away or switching off
- Judder at low revs
What a dual-mass flywheel does
Two masses joined by springs smooth out engine pulses before they reach the gearbox. Short journeys, low-rev driving and high torque accelerate wear.
It doesn’t always need replacing with the clutch, but it’s checked every time.
