Start with checking the motor mounts. Especially passenger side which has a known issue of the bolt breaking at times. If they have remove the passenger motor mount, they could have botched the bolt reinstall

Sound clip or Video may help instead of leaving it to my imagination.

Well..after 7....Yes friends..7 visits to the dealer, 2 advisors, 3 mechanics, one tensioner, 1 new serpentine belt 1 new AC compressor, Corporate intervention and finally the service manager involved, It turns out the culprit of the sound was the bracket that maintains the axle in place. The bracket had play, therefor making the stupid vibration. I mentioned that yhe axles and transmission was repaired by them and thats where i thought they should have started. The reason AC compressor was changed was that when it was turned on and off the vibration stopped and started....It was just the compressor changing the rate of vibration of the engine.

In any case: FORD FIESTA ST: NO RATTLES feels delicious on the road again.....

You'd think after they changed that and realized the sound is still there they would've kept looking on their own, right? Glad you had it resolved.
