One question I had was. Were you replacing gears into the same Diff cup? Or a Completely new diff each time? Only wondering if the cup itself is twisted...
So ReAssembled with stock parts or>???

Yes my arms are shimmed and everything else also to get rid of as much slop as possible. I used the same cups after inspecting them thoroughly. So I get your point there that it might have been part of the problem. This time, absolutely all the diff parts will be new. If this solves the problem, it will be a good example that cutting corners to save some money isn't always beneficial. The diffs will be reassembled with stock LST XXL parts.
I'm still waiting for the internal diff gears but yesterday I received the 5 mm Lunsford titanium steering turnbuckles I also ordered. I was still using the stock ones and they were often bending. Now instead of bending the turnbuckles, I'll probably break the steering uprights The ball ends had to be drilled to 4.2 mm in order to be able to screw them on those massive turnbuckles.
