I’be rebuilt the central diff twice today and it didn’t last long each time. At this point I doubt that printed diff will work for me. I was considering putting bearings between axles and housing but I’m not sure if that’s worth the effort. For now I think I get metal diffs so I can at least drive it.
I’m sorry to hear that! I just came back from another testdrive…
Are you driving or are you just spinning the internal gears inside the differential?
