Relatively new member with a first time question. I have a 93 F350 with a bale bed on it that has approx 280,000 mi. Just had a flywheel and clutch kit put in and now the truck makes a growling noise when idling along in most any gear. If you put power to the tranny the noise stops. Going down the road no noise. Any ideas as to what the problem could be? The new flywheel is solid instead of having the springs like the old one did. This is the first clutch repair to the truck.
