As an update, Removed turtle from torque tube and it was frozen. Drive shaft still would not turn, nor could I remove drive shaft gear and thrust washer. Soaked it with kroil over night.. Removed torque tube to carrier bolts. Used a small pipe wrench and turned torque tube and it and the driveshaft turned together to rotate wheels.Soaked the speedo gear again over night. A few raps with a hammmer on the trailing arm lug and the torque tube slide out along with the speedo gear and thrust washer. The area below the seal on the driveshaft was oily from the rearend dope and no rust visible. Still more evaluation is needed but I belive with new gear lube, drive shaft bearing, seal and cleaned up speedo gear, I believe the banjo will be fine.
