Hi all
just replace my clutch with the Exedy NF04 Lightweight flywheel. But I noticed that it makes a strange annoying knocking sound. It occurs when the car is warmed up. Barely audible at idle but it goes wild when driving and revving at lower rpm range.

Under low rpm range I can hear in the cabin while accelerating AND the trans or engine rattles along with it.

When u rev the car at stand still it makes the noise too, but with just a tiny touch on the clutch pedal it goes away.

Did replace the pilot and throw out bearings.
