Gasket between differential and rear axle housing, banjo
You have to pull out both drive shafts to then remove the diff block, if the drive shafts are firmly stuck, it is not because there is some locking on the drive shafts inside the diff block. The drive shafts are only attached with the 4 bolts inside the brake drum, then you may need e.g. a sliding hammer in case the bearing is rusted in the rear axle. Glue the diff gasket to the rear axle housing and it is easier to install, and of course you fill in new oil.
