Perhaps the difference in torque ratings between the FWD and AWD 01E's is due to the torque being shared between the front and rear differentials through a Thorsen (I don't recall the torque biasing of the Thorsen). As such, I suspect the weak link is the differential, so if one were to disable the rear output of an AWD trans, you'd probably end up with the same 262Nm rating. When time permits, I can look up the bearing part numbers, though I suspect they will be the same for both tran's.
