I've had the clutch/flywheel replaced in my 2007 Mazda BT-50 with a solid one; the previous was an anti-vibration one. Now when driving in any gear and if it's lagging a little bit the ute vibrates really badly in a certain rev-range. Would this be the new solid clutch doing this or something else?
Many owners have changed from a dual-mass flywheel when changing the clutch in their utes, and none have reported a major vibration problem after the change. I would doubt it is the flywheel that’s the problem, look elsewhere in the driveline.
