Power Steering Leak

[DarmahDan]

Hello All,  I'm hoping to tap into the combined wisdom here.  My 1998 2.6 V6  UK spec Cabriolet has had a catastrophic Power Steering fluid leak.  My initial thought was that it was the pump, but when I put fresh fluid into the reservoir it pours out from what appears to be the drive box (differential).  There is no obvious leak from the steering rack or pipes going to it.  Is there a take off that runs inside the gearbox/ diff area ?  Regards Dan
