Chef, problem is, Xterra found the problem with the M226 w/ e-locker rears...the side gear (I think he said on the passenger side) is very thin to make room for the locker. This seems to be what is failing in the rear diffs on the OR model.

This is my 2nd front diff (replaced the last one almost exactly a year ago).

There is obviously something wrong here and unless Nissan is going to keep replacing the diffs for us, we need a solution. I really hope what Xterra Racer is working on does the trick.
