torque setting diff crown gear v/hall combo 2003?

you have not said what your original problem was but these usually require special tools to correctly set up the pre load on the bearings and backlash between the pinion and crown wheel which is why most people fit a replacement box and setting these up is usually a specialised procedure.If you are determined to press on then you could google g/box specialists in your area,ask nicely and they may help you out.
