After months of working on my jeep I finally was able to take her for a joy ride. Only problem I found was a clanking from the drive shaft. When I got back to the house I parked it, then about 5 minutes later I went to back up in the garage and it wouldn't move. Put it in drive and the same result. It does go into gear as you can feel it. I gave it some gas and still wouldn't move, it felt almost as if the parking brake was set. I put it in neutral and same result. Applied the parking brake and released it a few times. Still wouldn't budge. Then I got a little upset and gave er hell. The result was a nasty clank then it would move somewhat with easy.... any ideas??
