wok 204 Posted April 22, 2020 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 ?

deankxf 20,231 Posted April 22, 2020 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 welded diff 1 gerg reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted April 24, 2020 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 pittingSent from my CPH1903 using Tapatalk Share this post Link to post Share on other sites
