So I am rebuilding the 10 bolt to match my recently installed 14bFF. The question I have is is there a way to replace the inner seal without pulling the ring and pinion? If not how hard is it to remove and replace the ring and pinion on a 10 bolt? Or do I even need to replace this inner seal? How do I know if it is bad? I know I should replace it but how difficult is it? /forums/images/graemlins/thinking.gif
