Volvo s80 2004 T6 - shake and unsettled

[omri75]

Hi guys
My car:
Volvo s80 2004 T6
The issue:
Car vibrates at speed above 100km/h , the gas pedel vibrate , steering also vibrates . car feels unsettled and unstable on the road and pull a tiny bit to the left. espacily on uneven roads. the car also feels uncomfortable , every tiny bit on the road is felt hard.. the feeling is there in "N" and in "D" , in N its less, but still there.

and another new problem: there is a clunk when leaving the gas pedal , when in gear and driving.
What i have done to solve the problem so far (no joy)..
4 Continental ContiContact2 Premuim tyres.
Car aligned 3 times.
Tyres aligned twice
New LEFT CV Axle complete (from EMPI)
Rebuilt right axle from local dist
New front shocks from Monroe , with new ZF (SACHS) Strut mounts , and Strut bearings.
Upper Engine Mount (the one on top of the engine with the strut brace)
Lower right engine mount( where the Vibration damper is)
new brakes
new rotors (back only was needed)
New transmission filter + oil.
any more suggestions ?

Wheel hub bearings?

Hi, thanks osman for yor reply.
I am not sure, it is the wheel bearing issue - but i do have a lot of tyre noise while driving espacily at high speed ( above 100) does all volvo s80 make noise above 100km/h ? how can i diagnose a bad bearing, while turning right hard i do hear kachhhh kachhh noises. (sounds like the wheel hits the plastic inside) but i am not sure.
i tried moving the wheels left / right (by hand) and i cant . they are solid. i also tried 12-6 position but no movement is felt.
