A while ago after I got stuck pretty bad my truck started to make a horrible grinding noise for a while. I found out the place where my CV axle bolt to closest to the front diff was pretty loose, or had a lot of play in it. After a little while before anyone could give me a stright answer the noise stoped. Now just a while ago the noise started again because I'm assuming the mud i went thought. I had my wheel bearings repacked and spendial bushings replaces and now its just as bad. So I'm assuming soe other bushing or bearing must be bad. Maybe on the side of the diff? I'll try to post a picture
