Engine Springs Recall Resulting Noise

[DavidN]

My '07 GS350 was one of those subject to the most recent recall, this one for replacement of the "engine springs" which was done late last week. Every since I can hear the engine and/or transmission, has anyone else had this problem? I bought the car new and it only has 22k or so on the odometer, tires are the ones that came with the car. This is my umpteenth Lexus and I can't recall being able to hear the engine and/or transmission, perhaps I'm delusional.

Thanks for taking the time to respond.
