Jerk/Jolts when releasing gas pedal

I've been driving around with this issue for quite a while, but no one, even the dealer, and some specialized shops, can get to the bottom of this. The problem that I am having is that the car jerks back, a bit violently even, whenever you let go of the gas pedal. If there's no music playing, but all windows are closed, you can evne hear the clunking sound coming from beneath the car. I've brought it to 2 dealers, and a specialized garage, and no one can figure out what's going on. These are the parts that have been replaced so far:

Gearbox Flywheel Gearbox support Front axes, left & right (I don't know if this is the correct term in English) - though this was related to another issue I'm having

I don't know where to look anymore, and it's ruined all of the fun in driving. Whenever I let go of the gas, it's a significant jolt. Also when I step on the gas again, but less so.

Does anyone have any idea whatsoever?
