Help: 2002 AWD Rolls in Park

I have 2002 AWD V8 Mountaineer Auto Tranny. I removed the front drive shaft
because the joint is bad. Now the truck will roll in park if the parking
brake is not on hard. I know the transfer case has a viscous coupling that
can slip and I read on another bulletin board that roll is normal with the
front drive shaft removed. However, I thought that the rear output of the
transfer case is directly connected to the input from the transmission,
with the viscous coupling only driving the front output shaft. Am I right
and if so, does that mean that the parking prawl in the automatic trans is
not working correctly? If there is a problem with the parking prawl, can it
be repaired/adjusted without a trany overhaul? Apprecate any help as this
has become a safety issue as my wife tends not to press hard enough on the
parking brake and today it started to roll after she parked. I adjusted the
parking brake to work better and I'm in the process of getting a new front
shaft, but if I need to fix the parking prawl as well I need to know.
Thanks.

Wow... I have the exact same problem. '98 AWD 5.0, I removed the front
driveshaft and now sometimes my wife has trouble with it rolling in park.
And I've been unsuccessful for six months finding a new (used) driveshaft.
Like you, I assumed that there is a mechanical connection to the rear wheels
but now I'm not so sure. Seems like too much of a coincidence that we'd
both have a bad driveshaft joint *and* a bad parking pawl.
