After a little looking around with no luck I decided to dig this old account up to see if any one might now what I'm talking about. I'm rolling a 91 rt4wd wagon and when I put it in reverse and back up it makes a clicking/clacking noise from the tranny. It has been doing it for about a year now, I don't believe it has gotten any louder or worse but I was wondering if any one has had this happen to their awd wagon and knows whats causing it or how to fix it?
