Hammering on the yoke will guarantee you'll need to replace the rear pinion bearing. It Brinnels the bearing race, and you'll have a noise, and very rapid pinion bearing wear. Use a 2-jaw puller with the jackscrew pushing against the center of the pinion gear, where you just removed the nut. You'll be able to replace the front bearing cone, but not the cup, and replace the grease seal. Any further disassembly will require either removing the pinion carrier if there's a ring of bolts holding it into the main carrier housing, or removing the whole center section if the pinion does not have its own housing. Be sure to save the gasket and whatever shims are behind the pinion carrier- - - -that's how the pinion gear depth is set on some rear ends.
