“just pull the diff” ha!
Yes, my nephews pulled the rear differential, disassembled it, removed the broken pinion, reassembled and reinstalled the now “super” open diff in the sand alongside a trail in Moab.
My niece’s husband sealed up the front hole with the handyman’s secret weapon. Tossed some new oil in the diff and drove off the trail and then back home.
Awesome work. Trailside repair for the win.
