That’s exactly why it’s not a drive shaft issue ..
Im by far a car designer or master mechanic engineer..
For them to replace sub frame bushes etc etc it has to do with transferring vibration..
Vibrations can travel from the strangest places to the strangest place ..
As for other vibrations after my car has been fixed well nothing that I would say I payed 55k aud for a cheap arse rocket on 4 wheels. That I don’t really expect.
Apart from the major blown high voltage module  6 weeks ago and the vibration that is now fixed the car for the mist part has done good ..
Little story back on 1995 I was a apprentice mechanic guy bought his brand new Camry in complaining of wind noise Forman bent the door frame a little help a bit nothing spectacular
The guy kept coming back complaining of a wind noise in the end the Forman said look go buy a merc or bmw this is a cheap car so expect these sort of issues ..
Problems like the vibration is an obvious fault and should be fixed no question but little other things revolves around the price you paid
