Hey guys! It has been awhile since I've posted but have rediscovered you.
My 78 280SE is having an odd issue, while accelerating the car has a very dull low vibration I can feel thru the steering wheel but not the gas pedal or brake...it feels like the flexi disc went bad (replaced last one nearly 4 years ago...) that seems worst as the car is in top gear and pulling slightly. Has anybody else had a similar issue? The car is in overall great shape with apx. 140,000 u.s. miles and an auto trans.
