When breaking down this problem you must look at the dynamics involved,
. Steering shakes, this indicates that there is a vibration setting in through the steering gear via the drive line, so the problem will be with the rotors, wheels, tyres, and to a lesser degree the drive shafts, faulty wheel bearings or loose suspension or steering components.
2. Body vibrations only under braking and not felt in the steering will be rear rotors.
3. Body vibration not felt in the steering under general driving will be generated in the wheels, tyres and rear drive line if a rear or constant 4 wheel drive.
Basically a vibration is something turning at speed that is unbalanced, so your mechanic can start to do a detailed diagnosis of this problem with this in mind.
Finally there is the issue of misalignment of drive line components, this is a lot more difficult to determine but it is something worth considering.
