Mysterious shuddering/vibration

Mysterious shuddering/vibration on a 2004 x3 with 130k miles awd.

Hi everyone, my x3 is shuddering under any acceleration. You could cruise 65 mph with no vibration at all but once you put gas on it the car violently shakes. It does it even at 5 mph. Both my shop and I are at a lost. Since this started I've replaced the ff:

-new shocks front and rear
-new wishbone and control arm bushings
-new motor mounts
-wheels are newly balanced and aligned

My shop basically checked off guibo (flex disc) and driveshaft saying that they're perfectly fine..

I'm at a lost ran out of ideas. Any thoughts on this?
