Did all Crew Cabs have locking rear diffs?

My 96 is a limited slip, but is more slip than not

Mine has the C9 LSD Code, but like said earlier, 'limited slip' is used very loosely.

Its been my experience that the Dana 70 limited slips are MUCH better than the 10.25's. Any tips on making the 10.25 lock up a little better? Im sure mine could use new clutch packs. My old 70 limited slip worked awesome at 200k, this 10.25 is worthless.

If it's a track lock, they are non serviceable throw away junk. If it's a powerlock (don't know if Ford ever used them) it can be rebuilt. My Jeep has a track lock that is smoked, I'm fixin to weld the spiders.

I believe the axle in my brown truck is a Dana 70, as is the axle in my 83 Explorer with unknown gears in it. I also have another Dana 70 with a true locker in it that I built for my grandpas truck restoration.

I was told by the guy I have setup all the gears in my axles that he could rebuild the limited slip diff in a 10.25. Is he mistaken?

What I really want to do next with my brown truck is put an electric locking diff in the front axle. That would be so awesome!
