The right axle shaft of my 1995 S320 (W140) recently sheared in half while pulling away from the lights.

How easy is it to replace the complete axle assembly? Is it simply a matter of removing the axle nut and unbolting the shaft assembly at the differential flange?

The old shaft should come out easy enough because it is broken in two but when installing the new shaft assembly does any of the suspension linkages have to be undone to allow clearance?

Finally does anyone know the size of the axle nut and the bolts holding the assembly onto the differential flange?
