vibration?????
 

okay my buddie has a 01 ws6. its got a bad vibration that goes with the rpms. at idle you cant feel it but when you rev it up to about 2000 you start to feel it. has anyone experienced this problem before???

Most likely drivetrain if its going with rpms. Maybe bad u joints. Is it speed or can you have it in neutral and rev it to 2k and then it shakes?

yea its in neutral but does it in drive as well
