Hey guys, 87 fc t2. I had a really bad vibration, the higher the rpms the worse it got. I did drive shaft, did nothing. Did motor mounts helped a lot but now only once and a while it gets really violent then goes away. Any ideas? Maybe transmounts?

Belt driven accessories can also cause vibrations. I had a bad water pump that would cause some series vibration around 4-5k RPM.

 

well i think i found out what it is, the motor just died today..sad day =(
