Check your diff action when using 93mm in the front. I tried it before but theres a notchy feeling when checking diff action it might wear your diff gears. Now im using 91mm with two shims inside, never pops out.

Was going to try the 777 outdrives but they are heavy, but I don't think they will be an issue with them breaking.
Also I had to switch to the 93mm front universals because the 91mm kept popping out.
