Zacacc: You need to pull the axels, then the ring gear assembly. Don't forget to remove the three set screws, they hold in the torque tube. Then you can use a block of wood and hammer on the front end of the drive shaft it should pop right out. Check out the shop manual there is a pretty good discription on how to do this. If you don't have one I would suggest that you make the investment, it's a big help.
