I just had another Duel mass flywheel and clutch installed....93+k miles.....1st was put in when truck was young because of a rear main leak....everything went fine with that one........this one not so much... a loud rubbing noise between 35- 43 mph in 4th gear(standard tranny 5 speed) rough idle at times that shakes the truck....didn't have before. Just need to know if I'm on the right track in telling the dealer that something is still wrong and how might I describe it to point to the flywheel and clutch? Rancher44
The vibrations could be an improperly balanced flywheel and it clutch assembly, causing movement an rubbing against the motor block off plate
flywheel It doesn't happen every time I come to an idle, but often enough to be a pain....would what you described cause it to happen every time or off and on??? Rancher
