Vibration from drive train.

[2jackmans]

When driving I feel a vibration in the steering column and in the car body. When I come to a stop with my foot on the break and the transmission in gear I feel the vibration. When the car is in neutral at a full stop with the engine running the vibration goes away.
Here is what I've had checked and ruled out:
1. Tires alignment and balancing okay.
2. Transmission was bad and had it replaced, including the rubber vibration damper.
3. Universal joints were worn and had the driveshaft with "U" joints replaced.
4. Flywheel replaced.
5. Motor mounts and strut replaced.
6. CV axles checked okay.
7. 6 cylinder engine runs smooth and well.
The vehicle has 100K miles on the odometer and is still vibrating. WHAT CAN IT BE?

Well since it continues while stopped, that automatically rules out lots of things that arent moving, axles, wheels, drive line components like axles and drive shafts.

When was the last service? Plugs, wires, etc? When not under any load (neutral) they may perform better than when under any load.

Motor mounts or transmission mounts
