Vibrating from 145km/h

Hello ! I’m an enthusiastic Volvo all-wheel driver (Freak) and I’ve never had any problems with Punto drive! The engines(Benzin) or gearbox(Automaton) have already been in their own way. Now with my current V70xc Bj98. switch M57. 160000km I have the following problem , from 145 km/h on the track the complete Fzg. starts to vibrate. The more speed the more annoying the Vibros. at 160 it gets to you the brain out. I myself am a little technically savvy and ha Be already Kardan and left front drive shaft replaced, without improvement of the Vibros. Wheels are to zero and have no height stroke, the brakes can not be either (no vibrations during braking). Please for help! Am currently kilometer eater , 500Km a week and does not want to be on the track with 130. Greetings to the Volvofreaks!
