the turbo noise is normal,
the vibration...start with a tire ballance, if its still there, the drivetrain needs to be looked into

Default vibration

ok....after further research and eval i have found that the vibration is better know as the "death wobble"! has anyone experienced this and if so what is the fix for it?

How about the harmonic balancer if there is one on a diesel?

if you have the death wobble, something is loose, check all steering, and knuckle ball joints, as well as the track bar
