Update - I was able to finish installing the rear diff with 5.38 R&P. After giving the rear diff a run of testing, I found a gravel lot where I could test everything in 4wd. It works! So it appears the OBX diff is actually working without catching gears - no bad noises when turning hard in any direction!!! It actually seems smooth. And I did jump back and forth between 2wd and 4wd to make sure the front axle was actually engaging... <img src="/forums/images/graemlins/shiner.gif" alt="" /> So far, so good. I will post more after I have a chance to hit a trail...
