Jeep rolls on even surface... T-case is bad?

So, guys. Finally my jeep gets lots of love, I even drove that thing to junk yard to pickup misc stuff for it. It made it just fine (about 100mi that day)
And this is when I discovered that jeep rolls on uneven surface. It does it very slowly, almost invisible, but everytime I got back it was in different spot. I was like "I could swear I parked closer". And yes! I've used E-Brake. Living in Seattle and in SF gave me that unkillable habit (I use it even on flat surface).
So I've discovered, that E-Brakes don't work, will have to fix that. And... It rolls when in P position.Is it a transfer case? Or transmission? I promised here not to do anything with T-case while it is good, well, the swap/VC fix will have to be performed sooner than I thought

Never heard of a bad VC causing the Jeep to roll. If anything it would bind it up and cause it not to roll. 93-95 will roll in park with the front drive shaft removed.
I believe there is a recall on the parking lever too.
To test the VC do tight figure 8's lock to lock. If it takes a lot of gas to move it and feels like it's hopping and binding then the VC is bad.

In my 1997 Limited ZJ, after driving about 300 miles with a bad VC, I parked at a McDonalds to grab some wifi and while my Jeep was in park and turned off it would keep... lurching forward maybe a half an inch or so every few seconds. It only did it once, and I could never get it to do it again. Not sure if it and the bad VC were related though.
