Gday, got a 9" diff , have removed the stuck brake drums etc, so now I can spin either axle by hand ( the other side then spins backwards - so its an open diff centre☹️ ), but the pinion doesn't rotate, and I cannot rotate the pinion by hand or with a long bar, I assume I will have to fully disassemble but thought id ask beforehand what might be the problem ?

was it in the rain(GABBED ) if the axles turn they are independent to the ring gear etc, so i can only expect the bearings on the carrier or pinion to be rusted or gears broken/rusted

unless someone welded it wrong for a locker

Oh that's a beauty... One for the wall of shame

I think those gears will be toast by the way. The case hardening will be gone from all the pitting
