How many miles in the car?
Is this a recent problem or something that has been going on for some time?

typical problem with bad/poorly rebuilt half-axles in automatic trans soobs. Vibration when stopped in gear - shift to park or neutral and vibrations stops.
seems like the only cure is Subaru axles, new or properly rebuilt. new aftermarket 'sometimes' work OK. The first EMPI I installed did not vibrate, the second one did.

OK, seems this is a different problem than I first thought.
do you feel shaking in the steering wheel or 'seat-of-the-pants' ?
many things to look at - start by shifting the front tires with the back. Inspect the tires as you do this.
alignment could be a little off, worn tie rods/rack bushings could be in the mix.
check lugnuts/studs, check for draggng brake caliper, loose axle nut. bad engine/transmission mounts.
any work done immediately before this began?

If you feel it in the wheel focus on front suspension and axles.
After that I would suspect driveshaft u-joints (if you can duplicate the problem by accelerating quickly) or possibly a problem with the AWD transfer clutches.
Is the shake speed related? Shakes harder/faster if you're going fast than it does when going slow?
Does it change if you press lightly on the brake pedal? (Just enough to make the brakes start slowing you down) What about if you brake heavily?
