i tought you broke the gear while bashing.
but you broke it due to modifying your differential, now i'm not woried about mine anymore.
and about the oil, with 50k there is not much resistance turning the wheels opposite deriction. so i might go even thicker in the future.
as serum say use atleast 30k.
the rear can be thinner oil (10k or 15k, 20k) as you want some traction.
i personally run 50k F/R as i like to slide.

byby and good luck with your diffs.
