I've been browsing this site and I must say you guys are awesome, I got some good ideas on what may be wrong with my jeep. The problem is I don't have the time to fix it myself and I didn't want to get screwed being that I'm a woman and all. So, I just wanted to say thanks for all the ideas. By the way, I believe that it's my front diff. Had a really bad snow fall and I've been putting the 4wd to good use, probably should have gotten it seviced first since I did buy it used. Thanks again.
