What I learned next is that the LCI manual X5s had large case rear diffs. The 4.4 rear diff is a medium case unit.

I found Green Dragon's old thread about doing the swap and he had mentioned he was successful in getting it done.

His inbox is full and I can't PM him so I'm asking out here, any one know what needs to be done to get the medium case diff to work in this situation?

Of if anyone can reach out to Green Dragon, I'll buy you beer lol

Also I can't access page 3 of that thread, anyone else with the same issue?
