A few weeks ago I got out in my 94 Jeep Wrangler and played in the snow during a major snow storm we had in KY recently. I came upon a couple that was stuck in the snow and to help them out. I placed my Jeep against there little Ford Escape car and pushed them several miles to a gas station. I came home and the next morning got up and went out in the mnts and played some more in the deep snow. The following day I drove it again and the 4 wheel drive worked fine. We got another snow that evening and when leaving to come home I noticed my Jeep was handling funny. It was struggling to climb what should have been an easy incline. I stopped and made sure I had my 4 wheel drive engaged, I did. Only my rear wheels were turning. I kept pulling on the 4 wheel drive shifter back and forth and finally it engaged. Well now to make this story shorted, it will not engage. So I went over in the garage and jacked all 4 wheels off the floor and placed the Jeep in 4 low or high and my front wheels will not turn. My drive shaft coming out of the transfer case is not turning. After reading this does anyone have a clue what night be wrong with my 4 wheel drive and keeping it from engaging. Has this happened to anyone before? Thank you.
