2.7 diesel model have the cv in the rear drive shaft, on the transfer case end and a uni joint on the diff end.
And here is the fun part. European model 1999-2001 with 3.1td has cv in the rear and front of driveshaft
I don't know is there WJ 3.1td there in Australia? I am from Finland here we have those 1999-2001. Then came 2.7 diesel with MB engine.
3.1 td is same motor that XJ 2.5td but 3.1 have 5 cylinders.
