What are my options other than an exact swap? I'm unclear as to which X250 differentials have the 3.07 rear end and would be a match.

 

>What are my options other than an exact swap?
My recollection is that you can't and are in deep do-do.
A few years back there was a large discussion of this problem and my recollection was that finding a good replacement was the only alternative.
Search back through the postings, I believe that is what you will find.
Sorry

You want the exact match. Newer model years used different length half shafts.

 

What's the problem with your diff? I've just installed a Quaife ATB in mine, several threads about that on this forum, but that's not going to help you if you have a problem with the crownwheel, pinion or housing.

 

I'm looking for options for replacing it with possibly an earlier rear differential.
