AROUND 5TH AND 6TH GEAR GOING AROUND 50-60 MPH IT STOPPED. IF I KEPT THE RPM UNDER 200 IT SEEMED TO RUN OK, NO ISSUE, BUT IF I PRESSED THE ACCELERATOR HARD OR GUNNED IT, IT WENT HAYWIRE. IT WAS THE RESULT OF A WORN AND DAMAGED DAMPENER OR DIAPHRAGM LOCATED ON THE CENTER SUPPORT BEARING. THIS CONDITION WILL ALLOW FOR THE DRIVE SHAFT TO TRAVEL UP AND DOWN WITH VARIATIONS IN DRIVE LINE TORQUE. THIS MOVEMENT WILL PRODUCE A LOUD CLANKING OR CLUNKING SOUND AND MAKE FOR A VERY UNCOMFORTABLE RIDE.
