dont forget about that fan clutch......it will cause a vibration. look at the shaft carefully and see if there is any evidence of it wobbling. you can also slip the belt off of it and see if the vibration goes away. thats right at the rpm where i noticed mine was going bad.

you did not state wether or not the vibration is in netural or not... also, with clutch ingauged or disinguaged. not at any speed, just parked in the driveway. does it vibrate same rpm with the above varables?
