Still haven't gotten my Tj to the shop to check the Transfer Case. We have been getting hit with storms in the North East like crazy. I had to park on a pile of ice (no other option). The next day I got stuck. I said for the hell of it let me try and see if my 4WD will work. It shifted from 2WD to 4WD with little to no resistance. I shifted it back to 2Wd then back to 4WD. I felt resistance and it engauged for a brief time, enough to get mo off the ice. The it started kicking and grinding and I shifted back to 2WD. Still hoping its the linkage and hoping that this was a good sign.
