its a '92 240, ka engine, originally a manual, installed a stage 1 clutch from exedy and fidanza flywheel. have a vibration in every gear, but its only noticeable in decel around 2500 down to 2000 rpm in 3rd and really bad in 4th/ it sounds like its coming from the diff but i think its just traveling through the whole powertrain. the driveshaft is in phase, i measured runout. i had the car up on a lift doing 10 mph and the tail shaft of the trans was wagging around so i thought it was the trans mount. i stuck a pole jack underneath it to take the weight of the trans off the mount and i could feel the vibration coming down the pole jack. i have a feeling that its the flywheel, maybe for some reason it wasnt balanced right or something else. Is anyone else having this problem and actually fixed it? i saw a few with no conclusion.
